Effect of ball and feed particle size distribution on the

01/06/2018· This approach has the added advantage in that different particle sizes can be effectively milled in a ball mill because each media size can effectively break a particular particle size during the size reduction process ensuring that the product fineness is optimized. The same policy is employed for the make-up charge where adding different ball sizes is done in order to optimize the mill

Particle Size Reduction Services Catalent

Catalent’s particle size reduction services are accomplished through the use of fluid energy jet mills. This type of mill operates on the principles of impact and attrition, generating high velocity collisions between particles that are suspended in a nitrogen gas or compressed air stream. The resulting impact causes the particles to break down into smaller fragments. Centrifugal forces in
