Impact or attrition or both are responsible for size reduction. Ball mill at low speed is used to produce fine powders, such as food colourants, pigments insecticides. It has a slowly rotating, horizontal steel cylinder which is half filled with steel balls cm in diameter

Ball milling is another popular size reduction technique used for the production of microparticles, especially in research laboratories. Fundamentally, a ball mill comprises a vessel or vial filled with balls, or rods, constructed from a variety of materials such as ceramic, agate, silicon nitride, sintered corundum, zirconia, chrome steel, Cr–Ni steel, tungsten carbide or plastic polyamide ( Fig. 2 ).

Impact, attrition, hammer mills, ball mills, colloid mills, sieves, sedimentation. Size reduction is the process of reducing the particle size of a substance to a finer state of subdivision to smaller pieces to coarse particles or to powder. Size reduction process is also referred to as comminution and grinding.

Our combined experience in ball mill design and process equipment development totals more than 60 years and allows us to put a unique spin on steel and lined mills. Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800's. The basic construction of a ball mill is a cylindrical container with journals at its axis.

frequently used interchangeably. Usually, however, a ball mill is referred to as one that uses steel balls as grinding media, while a pebble mill is one that uses flint pebbles or manufactured ceramic shapes. Fundamentally, milling is a process for reducing the particle size of solids to some required degree of subdivision. It is also a method for dispersion or
