If n= equation (2) becomes Rittinger's theory. 24. Rittinger's theory According to this theory energy E required for size reduction of unit mass is directly proportional to the new surface area produced. E=KR (Sn Si) .. (3) Where Si = initial surface area Sn = new specific surface area KR = Rittinger's constant.

6. HAMMER MILL MECHANISM Hammer mills reduce the particle size of materials by impacting a slow moving target, such as a cereal grain, with a rapidly moving transfer of energy resulting from the collision fractures the grain into many pieces. Since impact is the primary force used in a Hammer mill to reduce the size of the particles, so, whatever increases the chance of a collision ...
