Mill (grinding) - Wikipedia

In materials processing a grinder is a machine for producing fine particle size reduction through attrition and compressive forces at the grain size level. See also crusher for mechanisms producing larger particles. In general, grinding processes require a relatively large amount of energy; for this reason, an experimental method to measure the energy used locally during milling with different machines was recently proposed.

The miscanthus pellets showed very low K values in all mills (−0.9 in the ring-roller mill to 3.7 in the knife mill), indicating that none of the mills significantly reduced its particle size. The steam exploded pellets showed very high K values in the planetary ball mill (37.3), but negative values in the knife mill (−2.8), as the mill broke the pellets into chunks rather than particles.
