Mill maintenance

Time: 2019-12-18

Mill equipment generally includes Raymond mill, high pressure suspension roller mill, high pressure micro powder mill, superfine mill, European version mill, etc., because their principles are roughly the same, maintenance is basically the same.

Through our detailed explanations of equipment maintenance, we must develop good maintenance habits and achieve regular and regular maintenance of the mill to increase the life of the machine and create higher benefits for the enterprise.

First of all, the transmission part of the mill mainly uses rolling bearings. The maintenance here is to adhere to lubrication, ensure timing, and ensure the service life of the bearings.

For small mills, the feeding is basically manual. Remember not to add more or less. Just like people eat, if you eat more, you can support it. If you eat less, you will be hungry. Too much feed will cause the mill to block, which will affect the normal operation and reduce the output. Many customers often ask, why is the mill output low? That is why.

It must be noted that the work of the mill is that the grinding roller and the grinding ring are in close contact, and the powder is squeezed and ground to make powder. Because it is metal-to-metal contact, there must be no metal objects in the machine body, otherwise the grinding roller and the mill will be damaged Rings and other components. Why does the grinding roller break down in just a few days? That’s the reason, especially the screws cannot be dropped.

The milling machine of the JOYAL miner can adjust the fineness. The fineness of the finished product must be adjusted by the analysis machine according to the size, hardness and moisture of the material. Correspondingly, the fineness is increased, and the output will be reduced. When the rated requirements are not met, the fan speed can be adjusted.

When it comes to fan adjustment, we all know that it is to adjust the air volume of the fan of the mill. So where is the adjustment? There is an air volume control valve in the fan intake pipe, which is generally opened to the maximum. The control valve at the waste outlet exhaust pipe should also be slowly adjusted. It can be adjusted to ensure that no dust is ejected from the feed port. It must be an idea.

What is the replacement cycle of the grinding rollers and rings? In general, two sets of grinding rollers and one grinding ring, because the hardness of the material being milled is different, and the running time of the mill is different, so the replacement of the grinding roller and the grinding ring must be based on the actual situation. Here is a suggestion, that is, The scrapping period of the grinding roller and the grinding ring, the remaining minimum wall thickness must not be less than 10mm, and the components of the grinding machine must be replaced when this limit is reached.
