Reasonable size and ratio of steel ball. because the steel ball in the ball mill is in contact with the ore, and the ball diameter is too large, the crushing force is also large, which leads to the fracture of the ore along the direction of penetration force, rather than along the interface of different mineral crystals with weak bonding force.

Special design to ball mill which will be selected on the basis of hardness, grindability index of material to be ground, feed size, particle size and hourly capacity, customized to the liner. selection of grinding ball and rod can improve grinding efficiency farthest and reduce the energy.
The apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example: a 5 x 5 ball mill has a working diameter of 5 inside the liners and has 20 per cent more capacity than all other.
The cylinder length-diameter ratio of rod mill is generally 1.5-2.0, while the cylinder length-diameter ratio of ball mill is smaller, only slightly greater than 1. in addition, the cylinder speed of the rod mill is lower than that of the ball mill, so the grinding medium works in the cascading state. 2. discharging way of ball mill and rod.
The design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material (feeders), and the system for discharging the output product. the size of a mill is usually characterized by the ratio “length to diameter” and this ratio most frequently varies from 0.5 to 3.5..
