The main component of quartz stone is silica, which has good oxidation resistance, high temperature resistance, corrosion resistance, and stable physical and chemical properties. It is a commonly used industrial mineral raw material and has a wide range of applications. Quartz stone is generally processed into powder and used more, and quartz stone ultrafine vertical mill needs to be used.
With the development of industry, the demand for ultra-fine powder is getting higher and… Continue

The vertical roller mill
is mainly composed of feeding part, discharging part, rotating part, transmission part (reducer, small transmission gear, motor, electric control) and so on. Its main working part is a low-speed rotating cylinder mounted horizontally on the bearing, and the cylinder is equipped with a grinding body. The supporting device of the vertical roller mill should bear the rotating part of the whole mill, the grinding… Continue

The radial clearance of the bearing is too small, and the radial clearance of the ultrafine mill
bearing is too small, which will cause the bearing to over-grind and heat up, mainly because the bearing has a large bearing capacity, a high frequency, and the load keeps changing.
Solution: It is recommended that the bearing adopts a large clearance. If it is a bearing with… Continue

When the grinding mill
leaves the factory, the head shaft of the scraper mechanism and the reducer are often installed together. When installing on site, the head shaft and the reducer mesher should be disassembled first, reconnected to the scraper shaft of each slot, and the scraper shaft should be checked.
If the rotation is not flexible, you can add an adjustment pad between the scraper bearing seat… Continue

The partition board or grate seam is blocked by some sundries or debris. In severe cases, it is completely blocked, and the grate hole becomes smaller, which causes the vertical roller mill to be "full grinding". If the vertical roller mill
is not maintained regularly or is in disrepair for a long time, the partition plate may be partially broken off or perforated, causing the steel balls to pass through the warehouse and reducing the… Continue

The water content of the grinding material is too high (usually 2.0%), and the ventilation in the cylinder is poor, so that the water vapor and fine materials generated during the grinding process cannot be taken out of the vertical roller mill
It is too large and adheres to the surface of the steel ball and the lining plate of the vertical roller mill, which slows down the flow rate, makes the discharge of the… Continue
