The basis of size reduction can be by splitting or shearing with sharp knives in which the geometry of particles are almost the same or by crushing or shredding with blunt impacting tools in which the particles are damaged due to compression. In the case that the grinding mechanism is a cutting device it is called a chipper.

trical energy per annum in size-reduction operations. More than one-half of this energy is consumed in the crushing and grinding of minerals, one-quarter in the production of cement, one-eighth in coal, and one-eighth in agricultural products. THEORETICAL BACKGROUND Introduction The theoretical background for size reduction is

grinding machines perform the dressing task automatically. The application of coolants to the grinding process is important. Coolants reduce grinding machine power requirements, maintain work quality, stabilize part dimensions, and insure longer wheel life. Coolants are either emulsions, synthetic lubricants or special grinding oils.

Roll crushers have a theoretical MAXIMUM reduction ratio of 4:1. If a 2 inch particle is fed to the roll crusher the absolute smallest size is 1/2 inch. Roll crushers will only crush material down to a minimum particle size of about 10 Mesh (2 mm).

Clarification: Crushing efficiency is defined as the ratio of surface energy created by crushing during crushing to the energy absorbed by the solid. Single layer particle crushing was taken to be 100% efficient. 6. Which of the following law determine energy requirement in size reduction? a) Kick's law, Bond's law b) Rittinger's law

Powerpoints On Grinding In Mineral Processing Ppt Size Reduction Crushing Grinding.
