Description

Cement ball mill welt quick replacement device

Technical Field

The utility model relates to a quick replacement device field, in particular to cement ball mill welt quick replacement device.

Background

The cement ball mill is mainly used for grinding finished products and raw materials of cement plants, and is also suitable for grinding various ores and other grindable materials in industrial and mining enterprises of metallurgy, chemical industry, electric power and the like. The material is fed into the first bin of the ball mill by a feeding device through a hollow shaft, and the bin is internally provided with a stepped lining plate or a corrugated lining plate which is internally provided with steel balls with different specifications. After the material reaches rough grinding in the first bin, the material enters the second bin through the single-layer bin partition plate, the flat lining plate is inlaid in the bin, the steel ball is arranged in the bin, and the material is further ground. The powder is discharged through the discharging grate plate to finish the grinding operation. The liner plate needs to be replaced after a period of use. The bolt stretcher is a hydraulic stretcher for short, and the hydraulic stretcher determines the stretching force according to the tensile strength, yield coefficient and elongation of the material by means of a hydraulic source provided by a hydraulic booster pump, utilizes the stretching force generated by an ultrahigh pressure oil pump to stretch a bolt with force in an elastic deformation area, and slightly deforms the diameter of the bolt, so that a nut is easy to loosen. The stretcher has the greatest advantage that a plurality of bolts can be simultaneously fastened and dismounted in a fixed value, the force distribution is uniform, and the stretcher is a safe, efficient and quick tool which is the best way for fastening and dismounting bolts with various specifications. The method is applied to the fields of petrochemical industry, aerospace, mining, heavy machinery and the like.
