The General Function of Ball Mills. A ball mill is a grinder used for grinding and blending materials for mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. Appearance. Ball mills have various designs and functions, ranging from laboratory-scale versions to large industrial models.

Critical Speed: Critical speed is the hypothetical speed at which the centrifugal force is equal to the gravitational force, and the grinding media starts sticking to the inner shell of the equipment instead of falling freely.Grinding at or close to critical speed of the mill yields a poorer grinding efficiency. The ball mills are mostly operated at 65 …

from Mexico; ground the baryte in a roller mill at its Brownsville, Texas, plant, then sent the mineral to con-tract grinders throughout the US for size reduction to the 2- to 5-micron mean particle size (6-to 7-Hegman range) required by many of its customers. The contract grinders used air mills or stirred ball mills to grind the baryte.

Afterward, cement material was processed within the dry stirred mill and samples were collected from feed and product ends when the steady-state conditions were established. The results of the grinding tests on cement material together with its breakage results obtained from 2 cm and 4 cm diameter beds were used in the model fitting of the …
