Cement is widely used in the construction industry, typically stored in large hoppers before being dispensed and conveyed into equipment for filling bags, IBCs or other containers.
This study looks at the performance variation between three batches of Ordinary Portland Cement during hopper discharge and subsequent aerated conveyance. A selection of samples, which exhibited varying in-process performance, were selected, included one which had undergone surface treatment to improve flowability.
Surface treatment offers the opportunity to alter the flow properties of a powder in order to optimise process performance. The ability to control the flow properties of a cement, without significantly changing other physical properties, helps ensure consistent delivery.
The three samples were analysed using an FT4 Powder Rheometer® to identify the effect of the surface treatment, to identify whether flow properties had been optimised, without compromising other aspects of performance.
