Ball mill is the most important raw material preparation of aerated concrete equipment ball mill, used for grinding of lime, gypsum, sand, slag and other materials. Materials only after grinding to the required fineness fully mixed interactions, in order to make the products meet the strength, the grinding is an important process in the production of aerated concrete, power-intensive process of grinding, ball mill is generally aerated concrete factory in the motor maximum capacity equipment. The ball mill is simplified by the level of expected out of the hollow shaft and the grinding head parts, simplified as a long cylindrical tube equipped with a grinding body cylinder of steel manufacturing, steel liner and Simplified fixed, usually steel grinding body system ball, in accordance with different diameter and a certain percentage of the loaded barrel of steel grinding body segment. Be selected according to the granularity of the abrasive material, the material from the mill feed end of the hollow shaft into the cylinder body, when the rotation of the ball mill Simplified grinding body due to inertia and centrifugal force, the friction force, it posts near the cylinder liner cylinder away, was taken to a certain height when being thrown, due to its own gravity, the whereabouts of the grinding body like a projectile to the cylinder body materials crushed. Material from the feed device into the compound empty shaft spiral evenly into the mill first warehouse, the warehouse there are ladder liner or corrugated liner, built with different specifications steel ball, rotating cylinder produces centrifugal force to the ball a certain height After the fall, the thump and grind the material. The material in the first warehouse, coarse grinding by monolayer partition panel into the second position, the warehouse lined with flat lining with steel balls, the material further grinding. Powder discharged through the discharge grate plate to complete the grinding operation. Cylinder in the process of turning, grinding body slipping phenomenon, to the material to the grinding action in the slipping process, in order to effectively use the abrasive material granularity teach general 20 mesh pulverized when the mill body cylinder with compartment plate separated Sec dual positions become material into the first positions when they were crushed by the steel ball, the material into the second position when the steel end materials grinding finely ground material from the discharge end of the hollow qualified shaft discharge small particles of feed material pulverized when, as sand II slag, coarse fly ash, mill shell may from time to set up partitions, a single silo mill grinding volume of the steel segment .
