MODELING OF THE PROCESS OF COAL GRINDING
The effect of the grinding process depends on a very large number of parameters. These include quantities related to the material being comminuted, the grinding equipment, the method of supplying energy, etc. More-over, these quantities are very often characterized by randomness. Thus, the unique deterministic description

Cryomill - the perfect mill for cryogenic grinding - RETSCH
Usually, grinding only takes a few minutes so that the sample does not get warm during the process. If, however, longer grinding times are required, it is also possible to pre-select periods of intermediate cooling and the number of cryogenic cycles. All instrument parameters are retained during standby operation for subsequent processes.

Equipment Selection for Surface Mining: A Review
The process for creating a borrow-pit is sequential: rst explosives loosen the earth; then, exca-vating equipment removes small vertical layers (or benches) of material, as illustrated in Figure 1. Over time, these benches themselves are blasted, excavated and removed, making the borrow-pit wider and deeper.
