Ball mills need to be cleaned between shafts and tiles during operation

　　The ball mill is a key device for crushing the material after crushing. This type of grinding machine is equipped with a number of steel balls as a grinding medium in its cylinders. It is widely used in cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metal dressings and glass ceramics production, dry mill or wet milling of various ore and other coarable materials. The ball mill is suitable for grinding various ore and other materials. It is widely used in mineral processing, building materials and chemical industries. It can be divided into dry mill and wet milling method. According to different mining methods, it can be divided into two types: grid and overflow type.

　　The ball mill requires a clean environment between the shaft and tiles during operation. There is no gap between them. Once there is a gap, friction will increase heat generation and affect productivity and product quality. Lubricants are easily broken, and the invasion of various impurities will damage the lubricant to affect the work of the ball mill. Let's analyze the following three situations.

　　1. Air intrusion oil: it will make the oil and degrade, vibrate the hydraulic system and generate noise; the hydraulic component is unstable, the moving parts crawled, and the reversed shock. The method of solving this problem is to replace poor seals, check the joints of the pipe joint and hydraulic components, and tighten the loose bolts in time. 2. Water and water mixing: oil becomes milky white, causing hydraulic components to rust and accelerate wear. The solution is to allow oil to leave some oil water mixture from the bottom of the tank and replace the new oil in a serious condition. 3. Impurities in oil: degradation of oil, causing the moving parts of the pump, valve and other components, and the gap of the small hole is blocked, and the working performance of the pressure transfer system is severe. It also accelerates the wear of the component and reduces the components. Life. Our method is: Cleaning the tank before refueling, add a filter, and clean the filter in time, regularly replace the new oil.
