Ultrafine mill introduction

The ultrafine mill is a key equipment for grinding materials, widely used in powder-making production line such as cement, silicate sand, new-type building material, refractory material, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc. Ball mill can grind various ores and materials with dry type or wet type. There are two kinds of ultrafine mills, grate type and overfull type due to different ways of discharging material.

Usage (dry or wet): Ball mill is the key equipment for grinding after the crushing process, which is widely used in the manufacture industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics and can be used for the dry and wet grinding for all kinds of ores and other grind-able materials. This study has higher practicality value and can provide the same products with use for reference.

The reasons are as follows: 1 There isn’t much difference between the diameter and barrel length, so it doesn’t accord with the assumption of simplified supporting beam ( the beam length can be over five times the maximum size of the cross section ).2 The cylinder body is a kind of plate shell structure, and the deformation under stress is much complex. 3 The cylinder body contains a feed port, a discharge port and lining plate, which may cause stress concentration. So only fine calculation can make nearby stress distribution clear.
