the parameters of the mill. In another approach, the energy efficiency of milling may be improved by adjusting the parameters of the comminuted material with the use of chemical additives or water. Chemical additives may, however, have a negative environmental impact [22]. Energy savings may also be found in the ball mill drive systems.

Working of Fluid Energy Mill. The feed introduced into the fluid energy mill is pretreated to reduce the particles size to the order of 100 meshes. This enables the process to yield a product as small as 5 micrometers or less. Despite this, mills capable of output up to 40 kg/h are also available.
A better understanding of equipment and operation parameters can minimize the overall input energy. The popular size reduction equipments for agricultural produce, viz., hammer mill, ball mill, burr mill, jaw crusher, gyratory crusher, crushing roll, cutter mill, Reitz mill, and colloid mills, are explained using schematic diagrams.

12. If the rate of feed increased, coarser product will be obtained and if speed of rotation is increased the fineness for a given capacity is increases. During grinding, the balls themselves wear and are continuously replaced by new ones so that mill contains balls of various ages. Ball mill produces 1 to 50 ton/hr of powder and energy requirement of the ball mill is about 16 kwh/ton.

1. Hammer mills: In a hammer mill, swinging hammerheads are attached to a rotor that rotates at high speed inside a hardened casing. The hammer mill consists of a steel casing in which a central shaft is enclosed to which a number of swinging hammers are attached. When the shaft is rotated the hammers swing out to a radial position.
