Surface treatment offers the opportunity to alter the flow properties of a powder in order to optimise process performance. However, a method of quantifying the influence of the treatment is required, to ensure that flow properties have been optimised without compromising other aspects of performance.
Cement is widely used in the construction industry. It is typically stored in large hoppers before being dispensed and conveyed into equipment for filling bags, IBCs or other containers. The ability to control the flow properties of a cement, without significantly changing the particle size, helps ensure consistent delivery to subsequent operations in the process chain, delivering commercial benefits in terms of higher productivity and reduced waste.
This study uses the FT4 Powder Rheometer® to ensure that flow properties have been optimised without compromising other aspects of performance.
