Get Price#### The working principle of ball mill

· The ball mill consists of a metal cylinder and a ball. The working principle is that when the cylinder is rotated, the grinding body (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force. At a certain height, it will automatically fall and impact and grind the material in the cylinder to grind ...

Principle of overflow ball mill: the main component is a cylinder with diameter and length at a reasonable proportion. Driven by the transmission device, the cylinder rotates with the materials fed from the cylinder inlet and crushed by the falling impacts and autogenous grinding of the steel balls and ores in the cylinder. Due to the continuously feeding materials, the pressure pushes ...

· Also the open circuit distribution more closely follows the gradient of the cyclone overflow. If a ball mill circuit were to be fed two distributions, each with same P 80 but with the open and closed circuit gradients in Fig. 1, the closed circuit distribution would require more energy to grind to the final P 80. How much more energy is required is difficult to determine. However, for the ...

· There is a small gradient of higher hydraulic head, at the feed end, which produces a slurry current, starting at the feed end, and which picks up viscosity (fines) as it passes through the mill full of balls to the overflow exit at the opposite end. There is also a difference in ball sizes (segregation) between feed and overflow exit that aids flow. There is a ball screw separator which keeps ...

· The mill discharge from these mills consists of slurry, which goes to the ball mills for further grinding, and coarse pebbles/rocks, which are crushed and sent back to the mill. To maximize the capacity of these circuits, the general practice is to use grates with pebble ports (reaching 100 mm) instead of normal grate openings to increase the pebble removal. In addition, operating mills at ...
