All-radial-direction discharging ball mill

Abstract

An all-radial-direction discharging ball mill is composed of a main motor, a speed adjusting transmission device of the main motor, a feeding motor, a speed adjusting transmission device of the feeding motor, a feeding and spiral pushing device, a rotary barrel, a screen covered outside the rotary barrel, a lining plate assembly in the barrel, a grinding steel ball in the barrel, a ball mill supporting component and a discharging box. When the ball mill works, materials enter the barrel from a feeding port and are distributed in the barrel along the axial direction fast and evenly under the rotation effect. The materials rotate with the grinding steel ball, are ground and flow in reciprocating mode in a gap among a grinding chamber, a lining plate and the barrel ceaselessly till the materials are ground to be thin enough to penetrate through the steel screen to enter the discharging box. The ball mill works in a radial reciprocating moving mode, the radial discharging motion exists on a barrel wall along all the axial directions of the barrel, namely the ball mill discharges the materials in an all-radial-direction mode. Compared with a traditional ball mill, materials of the ball mill flow to a discharging end from a feeding end slowly, and the ball mill has the advantages of being high in grinding efficiency and material recovery rate.

Description

technical field [0001] The invention relates to a ball mill, in particular to a ball mill with full radial discharge as the discharge method. Background technique [0002] Ball mill is the key equipment for crushing bulk materials after primary crushing. It is widely used in cement, new building materials, refractory materials, ferrous non-ferrous metal beneficiation and glass ceramics and other production industries. Materials are subjected to dry or wet grinding. [0003] The main working part of the ball mill is a rotating cylinder mounted on two large bearings and placed horizontally, and a grinding body of a certain shape and size is installed in the cylinder. When the ball mill rotates, the grinding body rotates together with the cylinder, is brought to a certain height, falls freely under the action of gravity, and hits the material at the bottom to crush the material. In addition, during the rotation of the mill, the grinding body also slides and rolls, so there is...

AI Technical Summary

Problems solved by technology

[0006] The invention aims at the disadvantages of low grinding efficiency and low material recovery rate in the existing ball mill due to the material flowing along the axial direction, and provides a material that flows in axially from the inlet, and is screened and discharged from the rotary cylinder of the ball mill. The flow direction of the material in this ball mill is radial flow, which can be called a full radial discharge ball mill.
