Ball mills tumble iron or steel balls with the ore. The balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.% ore and 25% steel. The ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclones. More

The overflow ball mill is mainly used for the wet grinding various ores. In the grinding process, while continuously feeding materials to the mill, a certain amount of water is also continuously fed, so that the finely ground materials and water form a mixed fluid. The ore pulp is discharged from the mill in a selfflowing manner to complete ...

There is a large gap between the tip speed and power intensity of the lowspeed vertical mills and the highspeed horizontal mills. The VXP mill bridges the gap between highspeed and lowspeed mills. The VXPmills are designed for fine and ultra fine grinding applications. In practice, the mill performs best when the feed has a normal distribution.

This option comprises an open circuit SAG mill followed by a closedcircuit ball mill. Due to the high throughputs associated with this circuit, the ball mill is most often closed with a hydrocyclone classifier. The course material is returned to the ball mill feed and the fine overflow product reports to the downstream process.

Mill Type Overview. Three types of mill design are common. The Overflow Discharge mill is best suited for fine grinding to 75 106 microns.; The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 250 microns.; The CenterPeriphery Discharge mill has feed reporting from both ends and the product discharges ...

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.
