Working principle of overflow ball mill

Author:


Overflow type ball mill is a common ore grinding equipment, mainly composed of horizontal rotary cylinder, feeding device, discharge equipment, grinding block and so on. In the working process, the feed is input into the rotating cylinder through the feeding device, and the ore and the grinding block are tumbled, impacted and ground together in the cylinder to form the crushing and grinding of the ore. The function of the grinding block is similar to the "medium" of grinding, which can effectively beat and mill the ore, so that the ore particles gradually become smaller.
The overflow type ball mill is characterized by its internal screen and discharge device. In the ore grinding process, the ore particles will enter the mill with water or other media, and pass through the screen, the finer ore particles overflow through the screen to form ore slurry, and the larger ore particles will stay on the screen until they enter the cylinder again to continue grinding.
In general, the overflow-type ball mill crushes and pulverizes the ore through the movement of the grinding block, and then realizes the grinding process of the ore. Its working principle is simple and clear, easy to operate, is one of the indispensable important equipment in mining production.
