Ball Mill Operation. Ball mills ride on steel tires or supported on both ends by trunnions. Girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive. The prime movers are usually synchronized motors. During rotation, a portion of the charge is lifted along the inside perimeter.

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.

The cost of grinding with Hardinge Mills is remarkably low. It has been found, by comparing the operation of Conical Mills with cylindrical tube mills in the grinding of ore and limestone, that with the same ball load in both types of mills, the cylindrical mill will consume about 60 per cent, more power for the same work as will the Conical Mill.

The working principle of a ball mill is that as the cylindrical shell rotates, grinding elements in ball mills travel at different velocities. That process makes collision force, direction, and kinetic energy between elements vary with the ball charge, and creates friction and rubbing forces, collision energy to grind material into particles.

The mill has begun processing the material and anticipates a first pour of gold-silver doré bars within two weeks. Initially, Rodeo material will be processed at a rate of about 200 tonnes per day ("tpd"), running through the currently operational 10.5' by 13' ball mill.

Processing at the Velardeña oxide mill is expected to begin as soon as sufficient material containing greater than 3.0 grams per tonne gold has been hauled to the mill site to allow for continuous operation. Initial processing will be at a rate of about 200 tonnes per day ("tpd") through the currently operational 10.5' by 13' ball mill.

The disadvantages of ball mills include their considerable metal consumption and deterioration grinding media, as well as a lot of noise. Most of the energy useless lost during ball mill operation, leading to low it efficiency. But even a significant specific energy consumption for grinding material compensates beneficial effect by using mill.

Locking Out The Electrical Power – Once the ball mill operation is completed, the operator should disconnect the high-voltage electrical power. Operators should also test the circuit, once they are done with the task. Clean Up The Machine After Use – A ball mill should be cleaned up after every operation or at the end of the working day.
