(1) Types on the Basis of Cylinder. 1. Short Cylinder Ball Mill: The ball mill with the cylinder length (L) less than 2 times of the cylinder diameter, i.e. the ball mill with L ≤ 2D is short cylinder ball mill, which is usually of single bin structure, mainly used for rough grinding or primary grinding operation, and can realize the wide use of 2-3 ball mills in series.
80 of the limestone that was fed into the mill are 650 microns, 1950 microns, 47.5 microns and 85 microns respectively. The fabricated ball mill is efficient in its performance as the value of P 80 of the products from the mill (85 microns) is less than P 80 (100 microns) used in the design of the ball mill.

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

method for differentiating between the two minerals. In each test, I kg of 4 x 8 mesh material was ground at 60 per cent solids by weight(7) for short ... size in microns) is 0.61 and 0.63 for limestone ground in the ball mill and rod mill. respectively, and 0.87 for quartz ground in the ball mill and rod mill.
Ball mill with one camera. Lining of the inner drum: steel plates of type "wave". Dry grinding method. Shredding material is a mixture of limestone in which dolomite is heavily present. The material size in the feed of the ball mill is 0-20mm. Grinding requirement is the residue on a sieve 007 not more than 15%.
The method is based on the observation that the breakage of the top size in a ball mill follows a simple kinetic law. where p1 is the fraction of materials in size class 1 in the ball mill. k1 is the specific rate of breakage for materials in size class 1. Integration of this equation gives the logarithmic law
The ball milling method consists of balls and a mill chamber. A ball mill contains a stainless steel container and many small ball made up of iron, hardness ...
