Three Elements of Ball Mill Production and Processing

The operation of the ball mill is very important, involving a lot of factors, including: ball mill grinding method, feed ore speed, add so on. Therefore, develop a reasonable operating system to improve the operation of the ball mill operator level, and timely adjustment of the ball mill mine operating parameters, which are good basis for obtaining good ball mill grinding and beneficiation indicators. The following is a detailed explanation of the three elements:

1.The ball mill feed the ore speed: after the adjustment of the working parameters, the grinding machine to the ore should be kept constant, or in a very narrow range of changes, the general situation, in the case of wet ball mill, in order to control water, to ensure that the ball mill the appropriate grinding concentration and fineness. Ball mill grinding machine must be evenly fed. With the increase of the ore feeding speed, the content of the qualified grain size in the ball mill is reduced, and the absolute quantity of the qualified grain size of the ball mill is increased, the power consumption is reduced and the grinding efficiency of the ball mill is improved remarkably. When the nature of the ore changes, should be timely adjustment of the working conditions of the ball mill to make a balance.
2. The ball mill pulp concentration: the appropriate ball mill grinding concentration should be able to make the solid material evenly along the surface of the grinding media movement, while the material from the ball mill feed to the end of the discharge side of the flow. The pulp is too thick, the viscosity increases, the grinding media is also affected by the buoyancy is also larger, the effective density of the ball mill becomes smaller, the impact weakened, and even steel ball should be brought out of the ball mill, or block the ball mill lattice board, ball mill production efficiency dropped sharply.

When the slurry is thin when the fine ore sink, if the use of overflow ball mill. At this time the product will be thinner, and easy to produce smash, generally when the ore to a larger particle size, high cycle load, the grinding mill concentration is close to 80% is appropriate; when the ore contains more slime, lower grinding concentration, so that the pulp concentration is generally about 70%. When the ball mill contains more mud, the viscosity and concentration of the pulp will increase. In order to improve the fluidity and stability of the pulp, the dispersant and the coagulant can be added without affecting the milling operation of the ball mill.

3. When the slurry is thin when the fine ore sink, if the use of overflow ball mill. At this time the product will be thinner, and easy to produce smash, generally when the ore to a larger particle size, high cycle load, the grinding mill concentration is close to 80% is appropriate; when the ore contains more slime, lower grinding concentration, so that the pulp concentration is generally about 70%. When the ball mill contains more mud, the viscosity and concentration of the pulp will increase. In order to improve the fluidity and stability of the pulp, the dispersant and the coagulant can be added without affecting the milling operation of the ball mill.

Therefore, if you want to control the ball mill well, you must start from these three areas, so as to achieve better work efficiency.
