Milling is the machining process in which the removal of metal takes place due to the cutting action of a rotating milling cutter.In a milling machine, the cutter is rotating due to workpiece is fed against it.This machine can hold more than one tool at a time. The cutter rotates at high speed, and because of the many cutting edges, it removes metal at a very fast rate.

3.2 Shaft speed. The 2nd key design and operational aspect for a hammer mill is the rotation speed. As the milling principle is based on the energy of the impact, the higher the speed, the finer the product can be expected as the particles will hit the hammer at high speed, but also be sent against each other or against the screen at high speed.

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.

Wood that has been received at a pulp mill can be in different forms. It depends on the pulping process and the origin of the raw material. It may be received as bolts (short logs) of round-wood with the bark still attached, as chips about the size of a half-dollar that may have been produced from sawmill from debarked round wood elsewhere.
