Vertical lifting device of roller mill used for processing steel slag

Abstract

The invention relates to steel slag processing equipment, in particular to a vertical lifting device of a roller mill used for processing steel slag. The vertical lifting device comprises a housing, wherein a feeding hole is formed in the lower part of the housing; a first discharge hole is formed in the upper part of the housing; a motor is arranged outside the housing; a transmission roller and a turning roller are arranged in the housing; the transmission roller is connected with the motor; a first conveyor belt which is vertically arranged is arranged on the transmission roller and the turning roller; a plurality of conveying hoppers are arranged on the first conveyor belt; second discharge holes are formed in the lower par, close to the side wall of the first conveyor belt, of the conveying hoppers; a group of rotary shafts is arranged in the conveying hoppers; chain wheels are arranged on the rotary shafts; a second conveyor belt is arranged on the chain wheels; the second conveyor belt is positioned on the upper parts of the conveying hoppers; a sieve hole is formed in the second conveyor belt; gears are further arranged on the rotary shafts; a rack matched with the gears is arranged on the housing; and a collecting slot is formed inside the first conveyor belt. The vertical lifting device has the beneficial effect of improving the steel slag grinding efficiency of the roller mill.

Description

technical field [0001] The invention relates to processing equipment for steel slag, in particular to a vertical lifting device for a roller mill used for processing steel slag. Background technique [0002] In the grinding process of steel slag, roller mills are generally used for grinding. The existing operation is generally to directly put the steel slag particles formed by primary crushing into the roller mill, and the roller mill needs to grind the steel slag particles several times before the steel slag reaches the required particle diameter. However, when the steel slag particles are circulating, the steel slag particles that have been ground by the roller mill are directly put back into the roller mill, so that the finer particles in the steel slag are repeatedly ground, which hinders the grinding of larger particles by the roller mill , so that the grinding efficiency of the roller mill is low.
