Crushing work index Calculation Crushing, Screening

As Alex told you: The crushing work index you calculated appears mostly correct. The only correction factor that might affect the calculation is to correct for the efficiency of the motor -- the work index is based on motor output (pinion) power, whereas the measurement of motor power is usually based on motor input power.

Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue.

Mill (grinding) Wikipedia

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
