Ultra fine grinding mill lining board is often said that we can be divided into fixed liner and movable liner, belonging to the ultra fine grinding mill vulnerable parts, the wear of the lining plate is the type of abrasive wear. The wear of the lining material of superfine grinding equipment is different.
General superfine grinding equipment lining plate is made of steel and steel, and in some circumstances is made by steel. If the ultra fine grinding mill is used to grind the soft ore, the liner can be made of chilled steel. Because the liner is easy to wear, so that it can be quickly replaced with a new, so the lining plate can be replaced. The liner turns 180 degrees, in fact doubling its use. The lining plate is divided into several sections according to the width and the length in the large ultra fine grinding equipment, and the lining plate can also be exchanged with each other. The service life of the lining plate depends on the characteristics of the ore and the material quality of the lining board.
When ultra fine grinding mill grinding quartz ore, made of manganese steel liner, with an average of 3-6 months. Its general use period of 1-2 months to 2-3 years. Manganese steel consumption of 1 tons of ore per grinding is from 0.0045 to 0.028 kg. The consumption of each cast iron liner is 0.01 to 0.1 kg, with an average of about 0.05 kg.
The working lining is of various shapes: the grinding of fine and fragile rocks, the use of plain surface lining is reasonable. The protruding part of the lining plate is matched with the concave part of the corresponding lining plate
