A paper by Reg Freeman, managing director of Freeman Technology (Welland, UK), presented at the French National Symposium on Powder Science and Technology (23rd - 25th May 2007; Ecole des Mines d’Albi, France), examines the measurement of shear properties for consolidated and non-consolidated powders.
The paper is entitled ‘Measuring shear properties and normal stresses generated within a rotational shear cell for consolidated and non-consolidated powders’ and reports work carried out using the company’s FT4 powder rheometer. This universal powder tester characterizes powders using dynamic methodology complemented by shear testing and the measurement of bulk properties. Of particular interest in the paper is the relatively new area of study investigating very lightly stressed powders using shear cells.
The French National Symposium on Powder Science and Technology brings together scientists, process engineers and material scientists working in all the domains involving the industrial use of powders and finely divided solids. These include the chemical, pharmaceutical, and food industries as well as ceramics, powder metallurgy, cement etc. as well as the fundamental physics of granular media.

Freeman Technology will exhibit the FT4 Powder Rheometer at European Coatings Show (Exhibition: 8-10 May 2007 and the Nürnberg Congress: 7-9 May 2007; Nürnberg, Germany), highlighting to visitors its relevance for QC and process optimisation within the coatings industry. In a product presentation session, Reg Freeman will demonstrate operation of the FT4, emphasising the unique features that give the instrument unsurpassed reproducibility and repeatability.
A state-of-the-art system combining a patented dynamic testing methodology with shear and bulk property measurement, the FT4 is a universal powder tester with a proven track record within the coatings sector. It measures samples in a consolidated, conditioned, aerated and/or fluidised state, generating data that correlate directly with processing performance. It is therefore ideal for optimising the flow properties of powder formulations, predicting how powders will behave during processing and developing relevant QC specifications.
The FT4 uses a conditioning process and automated test programmes to deliver repeatable, reliable measurement. A typical test cycle takes only 5 minutes to complete, and results interpretation and analysis is rapid thanks to the very latest software. By comparing flow energy measurements made under different conditions with a baseline measure, basic flowability energy (BFE), the FT4 allows quantification of the impact on powder flow behaviour of important factors such as moisture and air content, attrition and segregation.
The Freeman team will be available throughout the show to discuss specific powder characterisation issues.

Freeman Technology will exhibit the FT4 Powder Rheometer at Interphex 2007 (24 -26 April 2007; New York, USA). The FT4, a state-of-the-art universal powder tester, is a valuable tool for the pharmaceutical industry offering automated bulk, shear and dynamic property measurement. The data generated correlate directly with various aspects of processing behaviour making the instrument ideal for formulation and process optimisation, and effective QC.
The efficiency of key unit operations such as tabletting and dosing depends on the optimal matching of powder properties and processing equipment. With the FT4 powders are tested in a consolidated, conditioned and aerated state to fully characterise behaviour and the factors influencing it. This facilitates the rapid identification of properties with a critical impact on performance. Recent studies, for example, have highlighted the importance of compressibility, shear strength and both unconsolidated and consolidated flow energy, for dosing operations.
The FT4’s patented dynamic methodology and unique conditioning step, coupled with automated test programmes that eliminate operator-to-operator variability, deliver unsurpassed precision, repeatability and reproducibility. As a result the instrument is highly differentiating. Testing is fast, a test programme is typically complete in around 5 minutes, while the latest software delivers rapid data analysis, remote from the laboratory where necessary.

At ACHEMA 2006 (15-19 May 2006; Frankfurt, Germany) Freeman Technology will demonstrate a new capability for the FT4 Powder Rheometer – ‘real time’ bulk density measurement. New software developments for the FT4 now make it possible to measure bulk density during the course of a test program. No additional hardware or instrumentation is needed. Subtle changes in bulk density that occur during repeat testing as the sample stabilizes are monitored precisely. This variable can now be measured easily as a function of, for example, degree of aeration/air flow rate.
These new software elements are easily incorporated into an existing user’s test program making this a valuable extension of the FT4’s capability. For new users, bulk density measurement will be provided as an integral part of the software package delivered with the instrument. As with all other FT4 test programs, bulk density measurement is fully automated.
Because the FT4 methodology is based on repeatable conditioning and consolidation processes it can be used to generate highly accurate and reproducible bulk density measurements. Dynamic studies of bulk density, under different test conditions, afford additional insight into powder behaviour and give processors more information about this critical parameter. Changes in bulk density resulting from consolidation, which have been widely linked with powder flowability, and from aeration, are expected to be of particular interest.

At the 5th World Congress on Particle Technology (April 23-27, 2006; Orlando, Florida), Freeman Technology will exhibit the FT4 Powder Rheometer – its fully automated universal powder tester for comprehensive and discriminating characterization of powder flowability. The company’s Managing Director, Reg Freeman, will present a paper at the conference discussing the use of the FT4 to determine the effect of flow additives on two types of starch.
In addition to determining the optimum level of additive for each powder in a variety of flow regimes, Freeman’s paper reviews the impact that differing optimum levels may have as a powder transfers from one stage of a process to another, and discusses the compromise between, for example, optimising for storage in a bin and the discharge from it.
Information on powder flow properties provides a firm basis for informed decision making at every stage of powder processing – from material formulation, through specifying plant and processing conditions, to storage and transport of the finished product. The FT4 with its wide range of fully automated options allows simulation of complex process conditions and full investigation of the flow characteristics of a powder under a variety of conditions.

Assessment of minimal amounts of sample useful for pharmaceutical actives and early stage formulations
Booth Number: 165
The 2005 AAPS Annual Meeting & Exposition (November 6-10, 2005; Nashville, TN), will see the US launch of new accessories for Freeman Technology’s FT4 Powder Rheometer. Leading these is the fully automated, small volume shear cell which can be used to measure volumes down to 3 ml or less, depending on the characteristics of the powder. This completely new module enables users to extend the range of shear testing applications on the FT4 to include those for which only very small amounts of sample are available. This encompasses many pharmaceutical actives, and materials, such as early stage formulations, where a wide range of tests must be carried out on limited supplies.
The FT4 is a universal powder rheometer that is used to conduct an array of powder flowability tests. These provide a means to characterize the flow properties of powder materials and relate them to performance in process. Where shear testing is required to complement flowability data, both the new small volume shear cell and the existing standard shear cell accessory offer significant advantages over conventional methods.
Shear testing using the FT4 is fully automated, minimizing operator involvement for greater repeatability and reproducibility of results. And it is fast, with tests completed in around 40 minutes. Measurements can be made at low levels of material consolidation, thanks to the system’s high sensitivity, and over a wide range of stresses up to 100 kPa, allowing simulation of many different packing conditions. Conditioning of material before testing ensures homogeneity and a high degree of repeatability.

The new Aeration Control Unit for Freeman Technology’s FT4 Powder Rheometer allows fine control of air flow through a powder under test and enables the automated measurement of the powder’s flow properties as a function of increasing levels of aeration. At maximum aeration - or for some powders, fluidisation - the energy required to make a powder flow is reduced by a measurable factor, known as the Aeration Ratio (AR). This varies from around 5 for cohesive powders to in excess of 1000 for fluidisable powders. It is therefore an important flow performance indicator.
The bulk properties of powders can be greatly affected by even small amounts of entrained air. The aeration control unit allows evaluation at very low air velocities down to 2mm/min. Aeration at higher velocities up to 2000 mm/min can examine the fluidisation behaviour that has important practical processing implications in many industries. These include toner production, powder coatings and pharmaceutical manufacturing.
The FT4 with the new aeration control unit can be used to determine the flow properties specification needed to optimise production and achieve the required product quality. In addition, the system can be used on a day-to-day basis to verify that powder flow properties meet the necessary specifications, for predictable and consistent processing performance.
Powders always contain air and the amount significantly alters the flowability of the powder bulk. Consolidation removes air and increases the friction between powder particles causing high resistance to flow. Aeration reduces flow resistance and can result in fluid-like behaviour. The rate of release of entrained air from a powder bulk is another important characteristic that can be determined using the FT4 with aeration control unit.
Full automation of the AR measurement on the FT4 Powder Rheometer enables its accurate and reproducible determination. The elimination of user variability allows confident discrimination of even small differences between powders, with data reproducibility typically better than 1%. Furthermore, unattended operation frees analyst time for other tasks.
In addition to its use in the laboratory, the FT4 Powder Rheometer with Aeration Control Unit can easily be set up close to a production line for routine QC measurements.
The Aeration Control Unit is one of a series of automated accessories for the FT4 Powder Rheometer, designed to fully automate powder testing procedures.

Organised by the Particle Characterisation Interest Group (PCIG) of the Royal Society of Chemistry, PSA 2005 focuses on particle characterisation and powder systems analysis.
On Wednesday 22nd September, as part of the sessions covering Bulk Powder Characterisation, Reg Freeman will present a paper entitled 'Measuring powder flow properties - a comparison of empirical dynamic measurements with single plane shear data'. This comparative study of powder flowability examines two techniques. One, the most recently introduced, is an empirical method that measures the energy needed to establish three-dimensional flow patterns at closely controlled packing conditions (FT4 Powder Rheometer). The other is the shear cell in which the powder sample is sheared across a single plane in order to determine its shear strength, cohesion and angle of internal friction.
A number of different powder types were evaluated. Key flowability parameters as determined by the FT4 Powder Rheometer are compared with shear test data to determine correlation.

Freeman Technology recently introduced a fully automated shear cell accessory for use on its FT4 Powder Rheometer. Now, work performed by an independent laboratory using BCR reference material CRM-116 (Community Bureau of Reference: BCR, Belgium), has confirmed the new shear cell’s ability to perform verifiable and highly repeatable shear tests. This reference material has been developed to allow verification of shear tests and experimental technique. As part of their overall evaluation of the FT4 Powder Rheometer, researchers at the LGPSD-CNRS laboratory at the École des Mines d’Albi in France have been working in conjunction with Freeman Technology’s Powder Applications Laboratory in the UK. Results from the work at the École des Mines d’Albi showed that measurements made on CRM-116 using the FT4 shear cell gave excellent agreement with the shear parameters specified for the standard.
The FT4 is a universal powder rheometer that is used to conduct an array of powder flowability tests that provide a means to characterise the flow properties of powder materials and relate these to performance in process. Where shear testing is required to complement flowability data, the new automated shear cell accessory offers significant advantages over conventional methods.
Shear testing using the FT4 is fully automated, minimizing operator involvement for greater repeatability and reproducibility of results. And it is fast, with tests completed in around 40 minutes. Measurements can be made at low levels of material compaction, thanks to the systems high sensitivity, and over a wide range of stresses up to 23 kPa, allowing simulation of many different packing conditions. Conditioning of material before testing ensures homogeneity and a high degree of repeatability. As little as 35ml of material is needed to perform the measurement.
The shear test involves simply selecting a test programme, preparing the sample, then starting the fully automated test sequence. The shear cell utilizes the FT4 powder rheometer’s inherent ability to control force, the rate of application of force and strain rate as part of the automated shear test.

Freeman Technology presents paper at RSC Meeting Particle Sizing / Characterisation for Foods and Pharmaceuticals |
|
 |
Venue: The Royal Society of Chemistry, Thomas Graham House, Science Park, Milton Road, Cambridge, CB4 0WF |
This one-day meeting will address issues in characterising and understanding complex systems in the food and pharmaceutical industries. It is hoped that the presentations will promote an exchange of views on the common issues that arise.
Reg Freeman will make a presentation entitled 'An Investigation into the Friability of Particles and how this affects the Flow Properties of Bulk Powder'. In this study, two phenomena associated with friable materials are considered. The first is how powder flowability is affected by attrition by examining how the flow energy of a microcrystalline cellulose material varies as a function of the shear stress it is subjected to in a mixing process. Attrition of friable materials results in the presence of fine material in the powder bulk which can also affect its flowability. In the second part of the investigation, samples of aluminium oxide trihydrate powders with varying proportions of fines were studied and variations in flow energies observed.

Freeman Technology exhibits powder rheometer at Pittcon 2003
Freeman Technology Booth No: 2800
At
Pittcon 2003, Freeman Technology will be exhibiting its latest instruments
for the measurement of powder flowability.
Freeman's patented powder rheometer provides comprehensive data on powder flow properties. This is in contrast to traditional methods that give a single number result. It allows databases of information to be constructed, delivering information that offers real benefits to industry in relation to formulation, manufacturing and quality control.
The Freeman Technology powder
rheometer works on a patented helical blade principle, where the blade
displaces powder as it moves along a helical path through the sample.
It is the only instrument on the market that measures both the axial force
and the rotational force (or torque) as the powder is displaced. These
measurements allow the flow properties to be described in terms of the
total energy required to produce flow.
This approach recognises the complex nature of powders and the need to evaluate flow properties in relation to the many key variables such as flow rate, aeration, consolidation and moisture content.

Freeman Technology provides instruments that measure and classify the flow properties of powders. The company's patented FT Powder Rheometer aids formulation of new materials, helps to optimise handling and processing, and can provide quality control standards that lead to real productivity and quality gains.
Reg Freeman said: 'We have worked hard to develop our unique concept for powder testing and, of course, have had ups and downs along the way. Overcoming the natural resistance to a new approach is always challenging but now, with FT Powder Rheometer systems installed at many major pharmaceutical and chemical companies around the world, the market is realising the real benefits that a comprehensive insight into the characteristics and properties of powders brings.'

Patented Powder Flow Rheometer on show at Powtech
Freeman Technology Stand No: 11-313
Freeman Technology provides instruments that measure and classify the flow properties of powders. On show at Powtech 2002 (8 - 10 October; Nürnberg, Germany www.powtech.de) will be the patented FT4 Powder Rheometer, a unique system that aids formulation of new materials, helps optimize handling and processing and can provide quality control standards that lead to real productivity and quality gains. The FT4 Powder Rheometer is an indispensable tool across many industries, and has been adopted by six of the top ten major pharmaceutical companies.
The traditional unreliability of flowability measurements arising from the unknown packing condition of test samples is overcome using the FT4, with its novel pre-conditioning procedure that makes the data exceptionally reproducible. Most of the factors that affect powder flow properties may now 
be assessed independently. For the first time information databases on powders can stand alongside those on solids and fluids.
The FT4 uses a patented helical blade principle, where the blade displaces powder as it moves along a helical path through the sample. Gentle to aggressive flow patterns and flow rates can be achieved depending on the direction and speed of movement. All forces acting on the blade are measured and used to calculate the work done to make the powder flow. These energy measurements form the basis of all flowability assessments.

Reg Freeman (CEO, Freeman Technology) will speak about powder rheology in relation to air and water content as part of the first day's programme at the Fluid Particle Interactions conference to be held in Barga, Italy from 25 - 30 August 2002 (www.engfnd.org/2ab.html).
The conference, which is organised by the United Engineering Foundation and co-sponsored by the American Institute of Chemical Engineers, is the sixth in a series on fluid particle interactions.
Conference sessions will focus on state-of-the art methodologies for measuring interactions between fluids and small particles; new or improved theories for better understanding of interactions; modelling or simulation describing local interactions and those manifested in industrial processes; emerging and current industrial applications where interactions between fluids and particles play a critical role; identifying research needs and defining technical problems for further research.

Following extensive trials over a three month rental period, technologists at the Rohm and Haas plant in Jarrow (UK) have purchased a Freeman Technology FT4 Powder Rheometer. The FT4 provides a novel and straightforward means of determining the flow properties of powders. It is now being used routinely at Rohm and Haas for the characterisation and quality control of raw materials.
Ms Philippa Clarke, Area Chemist at Rohm and Haas explained the importance of reliable powder characterisation: "We saw immediately the benefits of using the FT4 as it allows us to confirm that raw materials meet the stringent criteria necessary for efficient operation of our processes."
Reg Freeman, CEO Freeman Technology, emphasised the value of understanding powder behaviour, commenting: "Our experience has shown that in QC applications such as this, we can provide an almost immediate payback. In other areas, it is possible to derive substantial productivity benefits by designing in flow performance at the formulation stage, and through optimising the match between processing plant and powder characteristics."

The Harold Hayward Award for Innovation in Small Businesses is organised by the Institution of Electrical Engineers (IEE). The award committee usually recognises just one company annually. This year, however, because there was only the narrowest of margins between the strongest two entrants, the panel of judges decided to acknowledge both. Just missing out on the main award, Freeman Technology received a rare 'Highly Commended' certificate. The company's founder Reg Freeman, winner of the BT sponsored Entrepreneur of the Year Award in 2000, said: 'I am delighted that our achievements as a small business and the success of our FT4 Powder Rheometer have been recognised by this prestigious award panel.' |

Visit us on Booth# 16034 to discuss your powder flow problems.
Powder & Bulk Solids will be Freeman Technology's first appearance at a US exhibition and reflects the rapid development of the business over the past 18 months. During this time, the patented FT4 Powder Rheometer has proved its value in a diverse range of processing industries and has been adopted by six of the world's top ten pharmaceutical companies.
The ability to optimise powder handling and processing, and to develop sensitive, reliable QC criteria, opens the way to real productivity and quality gains, whether in pharmaceuticals, polymers, bulk chemicals, coal or a whole range of other powders and granulation processes.
The FT4 Powder Rheometer makes possible for the first time the direct comparison of powder flowability data from different samples, and opens the way to create information databases for use by formulators, developers and manufacturers. A novel pre-conditioning procedure ensures that measurements are repeatable and comparable, and most of the multitude of variables that affect powder flowability can be assessed independently.
The FT4 uses a patented helical blade principle, where the blade displaces powder as it moves along a helical path through the sample. A wide range of flow patterns and flow rates can be achieved depending on the direction and speed of movement. All forces acting on the blade when causing powder to flow are measured, and these data form the basis of a flowability assessment. Force measurements are converted into energy to determine the total energy or work done during the traverse.

Freeman Technology, manufacturer of the FT4 Powder Rheometer, has concluded discussions with Stable Micro Systems Ltd over patent rights for the technology involved in each company's product. By mutual agreement, Stable Micro Systems has ceased the manufacture and sale of its Manumit Powder Rheometer.
Reg Freeman, inventor of the technology, said: "Naturally we are pleased with the outcome. The FT4 offers a means of generating uniquely reproducible data on powder flowability, something that has been a great problem in the past. For the first time, there is the possibility of developing a database of information on powder characteristics, which will allow proper comparison and forecasting of powder behaviour under different conditions."
