Grinding process conditions and requirements of ball mill

The particle size of the material crushed by a ball mill When using the sieve ball mill to crush the material, the feed size should not be too large. If the material block is too large, the material will stay in the ball mill for a long time, which is easy to produce over-crushing and increase the micro powder

Using Micronization to Reduce API Particle Size

Jan 16, 2013The desired particle size depends on the solid-dosage requirements, notes Brian List, sales and marketing manager at the Jet Pulverizer Company, with typical API particle sizes in the 25 micrometer range. The minimum particle size that can be obtained using a jet mill depends on the inner friability of the material, explains List.

A NOVEL APPROACH TO OPTIMIZE GRINDING CIRCUITS

This approach can be easily employed in the monitoring of data and on-line control, to size reduction and manual flotation recovery. Sometimes there is not enough time to change the size reduction parameters (e.g. ball mill) to optimize the output size distribution. This means that the behaviours of size reduction equipment are a function of time.
