The energy-saving ball mill is the key equipment for crushing the material after it has been crushed. It is widely used in cement, silicate products, new building materials, refractory materials, fertilizer, black and non-ferrous metals and other metals and glass ceramics production industry, a variety of ores and other materials can be dry grinding or wet grinding . The six major reasons for the heat of the ball mill motor bearing The temperature of the energy-saving ball mill and the motor bearing rises. If it exceeds the regulations, it will seriously damage the energy-saving ball mill and affect the service life of the ball mill. Energy-saving ball mill motor bearing temperature is too high, there are six aspects. 1. Check the lubrication points of all parts of the energy-saving ball mill. The lubricating oil grades used are consistent with the factory specifications. 2. Check whether the energy-saving ball mill lubricant and grease are deteriorated. 3. Check if the lubrication pipeline of the energy-saving ball mill is blocked, or the lubricant does not directly enter the lubrication point, and the oil quantity is insufficient to cause heat. 4. The side clearance of the energy-saving ball mill bush is too small, the gap between the bush and the shaft is too large, and the contact points are too much to form a uniform oil film on the bearing bush. 5. The energy-saving ball mill rolling bearing has too much or too little grease. Excessive formation of rolling elements stirs the grease to generate heat, and the heat is not easy to dissipate. Too little lubrication, the amount of oil should be increased according to the regulations, generally 1/3 to 1/2 of the bearing clearance is more appropriate. 6. The sealing device of the hollow shaft at both ends of the energy-saving ball mill body is too tight, or the sealing body iron piece is directly in contact with the shaft. Vacuum forming machine is a simplified version of thermoforming, where a sheet of plastic is heated to a forming temperature, stretched onto a single-surface mold, and forced against the mold by a vacuum. This process can be used to form plastic into permanent objects such as turnpike signs and protective covers. Normally draft angles are present in the design of the mold (a recommended minimum of 3°) to ease removal of the formed plastic part from the mold.
