Ball Mill
Grinding Equipment
Ball Mill
Ball Mill is ore and material grinding equipment produced by DMTC Mining, a Chinese manufacturer of mining and mineral processing equipment based in Dalian, exporting to 100+ countries.
A ball mill is equipment that is used for grinding ores and other materials, so that it can obtain the desired product particle size.
The ball mill is mainly composed of the feed section, feed inlet, main bearing section, shell section, rotating section, discharge section, and the main motor, among other parts.
The motor drives the mill shell to rotate at an appropriate speed through the rotation and speed reduction of the gear pair. The grinding media inside the shell, under the combined action of centrifugal force, friction, and gravity, are lifted to a certain height and then fall in a throwing or dropping manner. The materials in the shell are crushed by the impact of the media. Meanwhile, due to the rolling or sliding of the media, the materials are ground by attrition. The ground materials are then discharged through the discharge opening.
