Powder Handling: Size Up Size Reduction | Chemical Processing
Ball mills, tube mills and ring-ball mills. A ball mill consists of a horizontal revolving cylinder containing a charge of tumbling or cascading balls, pebbles or rods. As a very rough indication, ball/rod charge may occupy 25–50% of the total internal volume of the mill.

Why use Different Size Balls in a Mill
The fine particle sizes are likely to be weighted too much; when the ball size for crushing 10-mesh sizes through 14-mesh is sought, the very fine sizes should be weighted with caution. A casual examination of each series for minimum of cumulative weights in the coarse sizes of the screen analyses probably would be a fair guide to the best ball size.

Ball Mills
Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.

Ball Mill
Ball mill is a type of grinder machine which uses steel ball as grinding medium, can crush and grind the materials to 35 mesh or finer, adopted in open or close circuit. . The feed materials can be dry or wet, they are broken by the force of impact and attrition that created by the different sized ba

SIZE REDUCTION
Thus, in the ball mill, impact or attrition or both are responsible for the size reduction. Advantages: It can produce very fine powder. Ball mill is used for both wet and dry grinding processes. Toxic substances can be ground, as the cylinder is closed system. installation, operation and labour costs are low.
