Influence of excessive stone particles on ultrafine mill

What effect does the stone particles have on the ultrafine mill?

In the grinding production process, the whole machine structure of the milling production line consists of the main machine, analysis machine, pipeline device, blower, jaw crusher, bucket elevator, silo, electromagnetic vibrating feeder, power distribution cabinet, etc. . The process is that the raw ore of the stone is firstly subjected to manual beneficiation, and the selected stone is selected, and then the hammer is broken (or broken) according to the size of the material, and then ground to a desired fineness by a grinding mill and collected. As the main grinding equipment, the ultra-fine grinding machine has no need to say much about its importance. However, the existence of the crusher in the production line process has caused many people to ignore it. Why configure a crusher? In fact, this is to prevent the material particles of the feed from being too large. Then why should we prevent the particles of the feed material from being too large, what effect does this have on the ultrafine mill?

Influence of excessive stone particles on ultrafine mill

When a large piece of material enters the grinding chamber, the material handling capacity of the machine is in a certain situation. With the continuous input of the material, the processing capacity of the machine cannot keep up with the output of the material, so that these materials accumulate in the grinding chamber, resulting in the product. The powder passage is blocked, causing serious production failure. Therefore, if the material is too large, it may cause the machine to block the material, thus hindering production.

In addition, if the feed particle size is too large, it may cause an increase in fineness of the powder. The fineness of the powder in this case refers to an increase in the proportion of the fine-grained material of the collected powder material, because the size of the discharge size of the ultra-fine mill is a relatively small range in the production of the flour. Within this range, as the feed particle size increases, the proportion of the treated larger powder material that can be blown away by the wind increases, so that the proportion of the larger particle size powder material passing through the classifier increases.

In addition, in the production process of ultra-fine mill, if the feed size increases, the failure rate of the machine will increase, which is undoubted, because the force of the bulk material on the accessories of the mill will also increase. Among these accessories, there are three main types of wearer parts: the roller sleeve, the grinding ring and the blade. Because these parts are in direct contact with the material, their wear will exceed expectations and the service life of the user parts will be made. reduce.

Excessive feed particle size is not only detrimental to the normal operation and fineness of the ultrafine mill on the surface, but also affects the service life of the mill accessories and the service life of the mill in the long run. Therefore, here our company recommends that the majority of users can configure a crusher when processing large ores, and crush the larger ore material with a crusher and then grind it, which not only reduces the ultrafine mill. The grinding burden, material fineness is guaranteed, and the life of the mill can be extended.
