ceramic ball mill Working principle
when ball mill working,steel balls inside drum will rotate with the drum to some height,and then steel balls fall down with materials to reach the point of grinding.
Working Principle of Ceramic ball mill
ceramic ball mill ,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.
Ceramic ball mill also named Intermittent ball mill which adopts the wet intermittent operation, is used for fine grinding and mixing the material such as feldspar, quartz, clay ceramic raw materials. The discharging and the mud size can through through 1000 sieve pore. This machine is high milling machinery, materials should be Broken in the fineness of the state into the grinding mill to get the highest efficiency and economic benefits.

Working Principle of Cement Mill
The cylinder will rotate by the transmission device. Due to the inertial centrifugal force, the steel balls will stick on the liner plate and rotate with the cylinder together. When the steel balls come to a certain height, it will fall down by gravity and impact the raw material. And the repeated going-up, falling down, slide and roll of the steel balls can grind the raw material together with the liner plates.
