Important role of ball mill in beneficiation plant

The following machine technicians of Henan Zhengzhou Mining Machinery Co.,Ltd. will clearly introduce the important role of ball mill in beneficiation plant. The beneficiation production process is as follows: The mined ore is coarsely crushed, mediumly crushed, finely crushed and sieved to achieve the specified grain size. Then, through the grinding equipment and the grading equipment, the obtained ore powder is separated by ore separation equipment such as flotation and magnetic separation. Finally, the selected concentrate powder is dewatered through a thickener and a filter to meet the transportation and smelting requirements. From the above, it can be seen that the beneficiation ball mill is the main equipment for mine beneficiation, and the position in the beneficiation process is relatively fixed. It is generally located after the crushing equipment, before the magnetic separator or flotation machine, and plays a turning point in the entire beneficiation process. It can separate and screen different minerals in the mineral and separate the tailings. It is crucial to improve the quality of the selected ore material. It can process a variety of materials that can be ground, non-ferrous metals, and new building materials. Next, Henan Zhengzhou Mining Machinery Co.,Ltd. will explain in detail the specific structure, working principle, and specific classification of the beneficiation ball mill. The beneficiation ball mill is composed of cylinder body, feeding part, discharge part, transmission part (reducer, small transmission gear, motor, electronic control) and other main parts. Its working principle: the raw material enters the rotary mill of the ball mill through the hollow shaft journal of the feeding device for grinding, and the rotating body is equipped with various diameter steel ball grinding bodies. When the rotating body rotates around the horizontal axis at a certain rotation speed, the grinding bodies and raw materials of the steel balls installed in the rotating body will reach a certain height along with the cylinder under the action of centrifugal force and friction force. When their own gravity is greater than the centrifugal force, they fall off or roll off the inner wall of the revolver, and crush the raw materials due to the impact force. At the same time, during the grinding and turning process, the sliding movement of the grinding bodies with each other also produces a grinding effect on the raw materials. As the raw material is continuously fed, its pressure causes the feed material in the rotary body to move toward the discharge end. After the raw material reaches the rough grinding in the first position, it enters the second position via a single-layered partition board. The leveling insert inserts a flat lining plate with steel balls inside and grinds the material further. The pulverized stream exits through the hollow neck of the discharge end. The beneficiation ball mill equipment also has different classifications depending on the production line, such as fly ash ball mills for fly ash production lines, wet ball mills for most beneficiation production lines, and so on. The types of beneficiation ball mills currently produced by the company include wet ball mills, dry ball mills, conical ball mills, fly ash ball mills, ceramic ball mills, energy-saving ball mills, cement ball mills and many other types of ball mills. Therefore, when selecting the beneficiation ball mill equipment, it is necessary to select a suitable ball mill according to the specific production line, so that the beneficiation production line can be produced at low cost, with high yield and with high efficiency.
