Dust is formed as a by-product of various processes, which include the transport of dry and powdered material, crushing and screening of solids, filling and storage of granular materials in tanks and reservoirs [1,2,3].Wood and wood-based wastes are also subject to the processes of reducing the size of the wood, e.g., chipping, etc.
Difference between crushing and grinding- Crushing ( dry) - Size reduction occurs preferentially on large fragments. Grinding (wet) - Size reduction is less selective- all pieces get ground to fine particles. 10. 12 S. No Process Size reduction 1. Explosive shattering Infinite size to 1 m 2.

grinding and crushing (Dean, 1995). Decreases in water content are sometimes observed while grinding solids containing essential water in the form of hydrates, likely as a result of localized heating. (See Section 12.3.1.2 for a discussion of the types of moisture present in solid samples.)
Before froth flotation can work, the ore to be treated is A thermodynamic approach was investigated to model the reduced to fine particles by crushing and grinding (a process removal of cupric ion using different surfactant types and ion known as comminution) so that the various minerals exist as flotation systems by liu et al., 2001.

crushing steps and different kind of crushers have been developed for different purposes. The size reduction ration is commonly between 5 and 10 in crushing stages, i.e. if the starting size is 1 meter in two-three stages the material can be crushed down to 1 mm particle size. Crushing is followed by grinding and it is quite common to use ...
