AISI steel grinding balls for ball mill applications typically have a tolerance of ±0.05/±0.10 and a density of 7.70 to 7.95. Exceptions include Al series 1XXX and Al 6061 which have the same tolerance but a density of 2.71 and 2.70 respectively and TCK 20/TCK 30 balls with a higher density of 14.85. Grinding balls data


Ball mill is a high-energy mill process especially used for an energy-intensive process like mechanical alloying, mechanochemistry, or mechanical activation. Planetary ball mill is used to determine the dependence of process efficiency using milling parameters such as ball size and number, mill geometry, and velocity of the rotating parts.

A material's susceptibility to wear depends on its physical and mechanical properties as well as on environmental factors, i.e., the conditions to which the material is exposed .In other words, the wear is a function of the tribosystem (), which is made up of four elements: body, counterbody, interfacial element and environment.The action of each one of …


mills can have correspondingly smaller sizes than usual. The material is dried in the ball mill. This system allows for the incorporation of several ball mills and permits separate pri-mary grinding of different components. The defined size of the feed material allows for optimum grading of the ball charge.

Ball mills consist of a hollow cylinder mounted such that it can be rotated on its horizontal longitudinal axis. Cylinder diameters can be greater than 3 m, although much smaller sizes are used pharmaceutically. The cylinder contains balls that occupy 30-50% of the total volume, ball size being dependent on feed and mill size.

The time has come to re-think the approach to mill drive motors because of the growth in size of newer ball mills, the starting torque restrictions of some of the newer mill drive configurations, and the softness of some utility services. This paper looks at the serviceability and economics of five different mill motor options to meet these restraints. Some approaches are …


Ball mill: Ball mills are the most widely used one. Rod mill: The rod mill has the highest efficiency when the feed size is <30mm and the discharge size is about 3mm with uniform particle size and light overcrushing phenomenon.

Ball Size as Initial Charge. Commercial ball sizes 10 – 150 mm; Number, size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge. For the initial chargin of a mill, Coghill and DeVaney (1937) defined the ball size as a function of the top size of the feed, i.e., dâ†"V = 0.40 ...
