Raw Material Preparation Wood received at a pulp mill may be in several different forms, depending on the pulping process and the origin of the raw material. It maybe received as bolts (short logs) of roundwood with the bark still attached, as chips about the size of a half-dollar that may have been produced from sawmill or veneer

Pin mill work by similar principle as hammer mills (impacts and shearing) but with typically faster tip speed rotor-stator configuration of intermeshing pins which impact the particles as solids are directed through the intermesh pins. The mill product leaves by centrifugal forces to the periphery and is then collected or further processed.

Principle of hammer mill. The hammer mill's functioning principle is straightforward. Fig. 2.2 illustrates the principle (a). All that is required is the selection of a suitable engine, crushing hammers/knives, and the material to be crushed. It works on the basis of impact between the rotor's fast-moving hammers and the stationary powder bed.
