•It’s the process that reduces large solid particles to smaller particles by mechanical means.
Factors affecting size reduction
1.Hardness .
2.Toughness.
3.Stickiness.
4.Abrasiveness.
5.Temperature.
6.Material Structure .
7.Moisture Content .
8.Physiological Effect .
9.Purity Required .
10.Ratio of Feed Size to Product Size
SIZE REDUCTION METHODS
There are many different types of size reduction method employed.
1.Cutting methods
•The material is cut by means of a sharp blade or blades.
2. Compression methods:
•The material is crushed by application of pressure.
3. Impact methods:
•Occurs when the material is stationary and is hit by an object moving at high speed or when the moving particles strikes a stationary surface. The materials shatter to smaller pieces.
4.Attrition methods: The material is subjected to pressure as in compression but the surfaces are moving relative to each other, resulting in shear forces which break the particles. 5. Combined impact and attrition methods
•A ball mill , fluid energy mills and pin mills are examples of a comminuting method which produces size reduction by both impact and attrition of particles.
Equipments
•All milling or Comminution equipment have three basic components:
1. A structure for feeding material to the mill.
2. The milling chamber and its working parts.
3. A receiver or collector in which the milled product is deposited.
