Thickening ball mill, ball milling method and thickening ball milling device

Abstract

The invention discloses a thickened ball mill. The thickened ball mill comprises a cylinder and a thickened ball mill body arranged in the cylinder, and the cylinder comprises a water inlet and a water outlet. When used, a raw material to be ground is put in the cylinder, wall and ball stones are added, the ball stones are once added and are supplemented when the ball stones are worn to a certain degree, the thickened ball mill is started, the raw material is ground through utilizing a ball milling principle, the raw material to be ground is momentarily added as needed in the working process of the thickened ball mill, water continuously enters from the water inlet and flows out from the water outlet, the small ground raw material suspends on the water surface or at the upper portion, the slight large ground raw material suspends at the middle portion, the large ground raw material suspends at the lower portion or the bottom, there is a granularity normal distribution of the whole ground raw material, and the ground raw material suspending on the water surface or at the upper portion will flows out with the water flow. The thickened ball mill can continuously grind, so the work efficiency is improved. The invention also discloses a thickened ball milling apparatus and a ball milling method.

Description

[0001] This application claims the priority of the Chinese patent application filed on November 29, 2012 with the application number 201220644773.X and the invention titled "a thickening ball mill and a thickening ball milling device", the entire contents of which are Incorporated herein by reference. technical field [0002] The invention relates to the technical field of ball mills, in particular to a thickening ball mill, a ball milling method and a thickening ball milling device. Background technique [0003] The ball mill is the key equipment for grinding after the material is crushed. It is widely used in cement, silicate products, new building materials, refractory materials, fertilizers, ferrous and non-ferrous metal beneficiation and glass ceramics and other production industries, dry or wet grinding of various ores and other grindable materials. Ball mills are suitable for grinding various ores and other materials, and are widely used in beneficiation, building ma...

AI Technical Summary

Problems solved by technology

[0004] When the existing thickened ball mill is in use, raw materials and water are added to the barrel of the thickened ball mill and ground, and when the raw material is ground to a qualified level, the machine is stopped for discharge, and the machine needs to be shut down to add water and take samples to check the materials in the middle of the grinding process Whether it meets the requirements, then discharge the ground raw materials, then add water and materials to the cylinder and then start the machine. This grinding method belongs to intermittent grinding, and the work efficiency is low.
