Attention to the repair and maintenance of superfine mill


The ultra-fine mill is mainly suitable for crushing equipment of mineral products such as metallurgy, building materials, chemical industry, mining and so on. The crushing range is: quartz, feldspar, china clay, pottery clay, bentonite, calcite, talc, barite, fluorite, clay, white clay, gypsum, etc., with a hardness below Mohs seven and a humidity below 6%. Flammable and explosive mineral materials. The superfine pulverizer has been used for a period of time to carry out regular maintenance and replace some worn or broken parts. In fact, we have to do the maintenance work in normal time. Don’t wait for the specified deadline or superfine The pulverizer was repaired only if there was a problem.

Pay attention to the quality when repairing the superfine mill. The following aspects are summarized:
1. The positioning pin used for positioning should meet the requirements of the contact surface with the surface of the two part holes in its working length to ensure positioning.
2. The main components should be fastened and reliable under the premise of ensuring the correct position; the fixed joint surface should be in close contact, and the 0.04mm feeler gauge cannot enter under normal circumstances.
3. The moving parts should be able to move flexibly and freely, no skew or jamming, and no overheating or abnormal noise in all parts.
4. When the ultra-fine mill equipment is working, all handles must not shake or move by themselves, or the phenomenon of dislocation stagnation.
5. All safety protection measures should be in place and in good technical condition.
Maintenance measures of superfine mill:
1. Replace the wearing parts in time. Because the ultra-fine mill is a high-energy-consuming product and equipment, it consumes a lot of power during the production process and easily damages the accessories, so it should be replaced in time.
2. Timely replacement of lubricating oil effectively reduces energy consumption and prolongs service life.
3. The machinery and equipment are all cast from steel and steel plates, which are easy to rust, so we should put them in a dry and ventilated place as much as possible.
