Ball mill principle work on Impact and Attrition. Both are responsible for size reduction, rapidly moving balls are used for reducing the size of brittle materials. Impact: Impact mean pressure exerted by two heavy objects. Attrition: Reduced the size of the materials when they colloid by heavy weight (Ball).

2. Introduction • The size reduction of solids is an energy intensive and highly inefficient process • 5% of all electricity generated is used in size reduction • Based on energy required for the creation of new surfaces, the industrial scale processes is generally less than 1% efficient. 3. Introduction Raw materials often occur in sizes ...
Fluid energy mill: PrincipleIt works on the principle of impact and attrition. It consists of a loop of a pipe, which has a diameter of 20 to 200 mm, depending on ...

Larger particles are fed through an opening of the cylinder. The opening is closed. The cylinder is rotated at the critical speed of ball mill. The optimum size reduction in a ball mill depends o the following factors: Feed quantity: Too much feed will produce cushioning effect and too little feed will produce loss of efficiency of the mill.

ROD/TUBE MILL BALL MILL •A tube mill is a continuous mill with a long cylindrical shell. •The product obtained is 2to 5 times shorter than that obtained from ball mill. •The working of tube mill is like ball mill. •The half of the volume of the mill is filled with balls or tubes and void fraction in the mass of balls or tubes at rest ...
Unlike the ball mill, there is no grinding medium is used in the fluid energy mill for the size reduction of the materials. Due to the expansion of the gas in the chamber, temperature in the mill decreases which enables the use of the fluid energy mill for the milling of thermolabile substances (Lachman et al., 1987) (Fig. ).
