Cement Kilns: Size Reduction and Grinding

The development of all-steel media allowed maximum grinding effect in these mills, but the rate of wear of these media was very high, often around 1 kg per tonne of material ground. Although hard alloys were available, they tended to be brittle, and hard media would break into irregular pieces, causing a rapid reduction in grinding efficiency.

Particle Size Reduction

Particle size reduction, or grinding, is a process to produce a polymer powder necessary for a particular industry or technology. This can be accomplished by starting with resin pellets or a powder that is ground to a finer powder. At Ancos, we can achieve a range of desired size distributions to meet specifications, from coarse to fine.
