The function of the partition plate of the cone ball mill

The ball mill is a device that grinds the material after crushing it. In detail, the ball mill performs two operations, crushing and grinding. There is a big difference in the nature of these two operations, so the ball mill must have a special structure to separate the division of labor of these two operations. This special structure is called a partition plate on the ball mill. The partition plate is crucial to the ball mill. Its function runs through the entire production process of the ball mill. Generally speaking, there are several points that we think are important:

1. Separate different types of grinding bodies. The different types of grinding bodies determine the role they play in the grinding process of the ball mill. The larger grinding body is mainly used for material crushing, while the fine grinding is performed by the smaller grinding body. This details the division of labor and ensures the quality of the product and the operating efficiency of the ball mill.

2. Avoid blockage. Blockage is a major operating obstacle of the ball mill. The establishment of the partition plate has a selection effect on the material, so that blockage is unlikely to occur at the discharge port.

3. Limit the flow rate of the material. If the material flows too fast, it cannot be fully ground. The partition plate slows down the flow of the material in the ball mill, controls the material grinding process, and increases manual operability.

Through these effects, we can see that the effect of the partition plate of the ball mill is very important, so let's make a brief introduction to the partition plate.

The material of the partition plate of the cone ball mill is usually high manganese steel or high carbon steel. This material ensures that the partition plate has sufficient hardness and can withstand the impact of the grinding body and materials for a long time. The partition plates of the ball mills used by a large number of our users are generally one or two layers. For the question of how many layers of partition plates to use, we have given a calculation standard: L/D=2.0, use a single layer; L/D=2.0-3.0, double layers; L/D=3.0, you can consider using three or four layers. In addition to the need to solve the problem of how many layers, the detailed design of the partition plate is also a certain consideration. We summarize it as follows:

1. The demand for the grate holes of the partition plate. The more grate holes, the better, and the smoother, the better, so that the ball mill can increase the material passing area.

2. Requirements for the partition plate itself. In addition to the hardness we mentioned, the partition plate is still as thin as possible.

If you have a better grasp of these, the effect of the partition plate can be more fully exerted. In addition to what we have said, we also need to learn a series of ball mill knowledge such as the manufacturing technology of the partition plate, so that our production activities will become more efficient and reasonable.
