The operation of a planetary ball mill under wet or dry state is another decisive factor that must be considered to make the grinding process successful. Pretreatment of lignocellulosic biomass in the wet or dry state produces different results. This is due to the difference in mechanism between dry and wet modes .

Molybdenum Processing - IMOA

Ball or rod mills crush and grind the mined ore to fine particles that may be only microns (10-3 mm) in diameter, releasing molybdenite from the gangue (worthless rock). The grinding mills on the right reduce rocks the size of soccer balls to the size of gravel. Further ball milling reduces the material to the consistency of face powder.

Fig 2, Heat Migration in Cold Mill Work rolls (Hotter regions shown in red) This localized heat input / output process results in a non-uniform distribution of heat, circumferentially around the roll and transversely across the roll body. Additionally the roll is subjected to Thermal and Mechanical Fatigue during rolling:

Micronization in the pharmaceutical industry

A jet mill cools the temperature of the air leaving the jets to about -200°F due to the Joule-Thomson effect, and the product leaves the mill no warmer than the air used for the grinding. The heat generated by the friction from particle-to-particle and particle-to-wall collisions is offset by the cooling effect of the expanding air.

Cement Grinding - Mineral Processing & Metallurgy

A typical raw mix consists of 75-85% limestone, 12-25% shale, the balance consisting of silica or quartzite and iron oxide. Exact proportioning is dependent upon their chemical properties before and after calcining to cement clinker. For good kiln practice the grind required is 88-92% – 200 mesh for standard cement, 99%-200 mesh for high early.
