Intermittent ball mill Brief Introduction:

Intermittent ball mill ,also called batch ball mill.can be used to grind feldspar, quartz, clay, silica and other hard brittle materials. It is widely applied in industrial production of high fine grinding materials. Intermittent ball mill grinding has dry and wet ways, of which the dry grinding can produce ultra-fine powder with the fineness of 1000-16000 mesh.

 Intermittent ball mill Working Principle:

Intermittent ball mill grinding operation is finished in the cylinder body. When the cylinder rotates, materials ascend to a certain height and then fall along a certain path due to the balls’ gravity. Two forces are generated on the balls inside. One is the force on balls through tangent direction; the other is a opposite force in the contrast to the diameter of balls, as a result of the force generated when the balls slide down. These two forces will constitute a couple for the steel balls. The balls are squeezed between the cylinder and the adjacent steel balls, so the couple can make unequal-sized friction force. The balls will orbit along with the cylinder axis and then fall down, which can produce a strong impact force on the ores in the cylinder body and, as a result, the ores will be crushed. In conclusion, the ores in the cylinder body are mainly crushed by composite effect of peeling force, impact force and extrusion force.

Intermittent ball mill features:

1. Low price and energy consumption.

2. Simple structure and convenient maintenance.

3. Easy installation and adjustment.

4. Various models of liners and types of medium for selection according to specific gravity and hardness of materials.
