Since the material feeding amount of the grinding machine exceeds the maximum passing capacity and the discharge amount of the grinding machine volume, the phenomenon that the grinding machine gradually pushes the grinding ability is called the phenomenon of "swelling belly" of the grinding machine. The swelling of the wet grinding machine is divided into two types: "dry expansion" and "wet expansion". The grinding machine "swells up", on the one hand, the grinding machine loses the ability to grind the ore, on the other hand, the serious swelling of the belly will cause damage to the grinding machine. When the stomach is severely inflated, the inlet and discharge ports of the overflow ball mill will spit out a large ore and ball, and the lattice ball mill will spit and spit from the feed port. In the case of closed-circuit grinding, the above situation will cause a large amount of materials and balls to enter the returning sandbox, causing the mining device to collide with the material and the ball, crushing the feeder and the returning bin, causing the scoop head to fall off or the ore feeder. The connecting bolts of the various parts of the body are deformed or sheared, and the concentricity of the ore feeder and the hollow journal is broken. In severe cases, the mill may vibrate or jump, causing impact loads on the bearings and gears, thereby damaging the shaft and damaging the gears. Therefore, to prevent swelling, especially to prevent serious swelling. Serious swelling will be treated as an accident.
