Since we’ve acquired the FT-4 (the first one in Brazil by the way) many companies have contacted us showing their problems in handling solids materials and asking for solutions. This has showed us how bulk solids handling is misunderstood in our country. Very basic Scientific works were developed at FEI to help our collaborators that consisted only in well characterised powders. In this task the FT-4 was fabulous because it offers the best possible measurement capability. It was evident to us that a free flowing powder hasn’t necessarily got better permeability, a test till now unknown by so many companies that becomes indispensable.
I experienced the highest level of service and support from Freeman Tech. The Freeman Technology FT4 is an excellent instrument for powder flow characterization and is extremely well supported by knowledgeable technical resources. I have experience with this instrument and company when working as a Senior Engineer at a previous employer and I would recommend it without reservation
Very happy with the excellent service provided by Freeman Technology. The MTC includes a world-class Powder Analysis centre and the Freeman FT4 is an integral piece of equipment within our Laboratory. The technical support and help given with regards to data analysis and interpretation is very much appreciated. (The MTC undertakes industrially driven research, working with world-class research partners, transferring cutting edge technologies into manufacturing processes in industry)
We have used the Freeman Technology FT4 for over 4 years. The range of characterization provided by the FT4 has proven to be a great asset to our ongoing research of powder behavior and dynamics. In addition, the members of the Freeman Technology team are available for discussions regarding everything from routine maintenance to data analysis assistance to theoretical topics.
Excellent software, easy to use.
FT4 is a great piece of equipment. We use it to characterize field crop and vegetable seeds and powders of various nature. The instructions, the initial training and the follow up training is outstanding. The Freeman Applications team is very prompt in getting back to us and answering our questions
At AEL Mining Services we have used the FT4 to identify the best binder for spray drying pyrotechnic delay compositions. The FT4 also allowed us to optimise the binder content in the pyrotechnic formulation and minimise breaking of the spray dried particles during processing. The FT4 was also used to identify the most suitable flow agent for PETN (pentaerythritoltetranitrate) which is used as the base charge in detonators manufactured on automated detonator manufacturing plant. The FT4 enabled us to optimise the quantity of flow additive added as well as the mixing time. We were also able to identify differences in PETN batches produced at AEL Mining Services w.r.t. conditioned bulk density, specific energy, basic flow energy and stability. Personally I have found after sales service excellent w.r.t. training done at Freeman Technology in the UK, servicing and updating of our instrument in South Africa and assistance from Freeman Technology experts in developing specific tests for the explosives industry.
We have found the Freeman FT4 Powder Rheometer helps our clients identify differences in flow properties between formulations, suppliers and products. The FT4 provides a comprehensive set of analyses for distinguishing bulk property differences which are impacted by the micro-scale properties our inhouse particle characterization techniques provide. This, in combination with Freeman's knowledgeable and helpful technical experts, allow us to provide additional added value to our clients.
