Abstract

The invention relates to a ball mill sliding shoe abrasion repairing method, and belongs to the technical field of ball mill maintenance. According to the ball mill sliding shoe abrasion repairing method, a sliding shoe (8) arranged on the end of a grinding barrel of a ball mill is included, and lining plates are fixed to the inner wall of the grinding barrel and the inner wall of a web (3) at theend of the grinding barrel through lining plate fixing bolts (2). The method is characterized by including the following steps of a, polishing the sliding shoe (8); b, repairing the thickness defectof the sliding shoe (8); c, conducting anti-seepage treatment on the sliding shoe (8); d, conducting structural adhesive reinforcing on the sliding shoe (8); e, installing reinforcing plates (4); andf, installing new lining plates. By means of the ball mill sliding shoe abrasion repairing method, the defects of huge cost and the long working period caused when the sliding shoe is repaired by using a traditional hot melt welding technology are overcome, and the economical loss caused by the abnormality of the ball mill due to repairing is greatly reduced.

Description

technical field [0001] The invention discloses a method for repairing sliding shoe wear of a ball mill, which belongs to the technical field of ball mill maintenance. Background technique [0002] The ball mill is the core equipment of the whole cement grinding system, which is related to the operation efficiency of the whole powder system. The ball mill is composed of a horizontal cylinder, a hollow shaft for feeding and discharging materials, and a grinding head. The cylinder is a long grinding cylinder with grinding bodies inside. The cylinder of the grinding cylinder is made of steel plate. , A liner is generally fixed on the inner wall of the grinding cylinder. [0003] During the working process of the ball mill, although the lining plate in the grinding cylinder has high wear resistance, it will also cause wear. Once the liner is worn, the grinding body will contact the inner wall of the sliding shoe along with the gap formed by the wearing of the liner and wear the...
