A kind of lining plate of ball mill barrel

Abstract

The invention discloses a ball mill cylinder body interior lining plate, solves the problem of relatively high replacement frequency in a conventional device, and is characterized in that the cylinder body lining plate is formed by head-to-tail combination of a plurality of rubber lining plates, and is mounted on a ball mill cylinder body steel plate (9) through T-shaped bolts (10); each rubber lining plate is a whole, is prepared by composite vulcanization of high-performance rubber and a reinforcing fabric skeleton, is P-shaped, and includes a tightly-pressing convex step, the fabric skeleton, a semicircular block, a circular through hole, a T-shaped bolt mounting groove, a flat lining plate, and a tightly-pressing concave step; each two adjacent rubber lining plates are successively laminated together through the tightly-pressing convex step and the tightly-pressing concave step, and the plurality of rubber lining plates form a circumference; a groove is formed between each two adjacent semicircular blocks. The ball mill cylinder body interior lining plate can be widely used in exploitation, ore dressing, metallurgy, cement, coal mines, steel, wharfs, electric power and other enterprises having heavy impact transferring points, can bear larger impact load, and has the advantages of impact resistance, high wear resistance, convenient installation, maintenance and replacement, stable product quality and long service life.

Description

technical field [0001] The invention relates to a mine and wharf material crushing equipment, and more precisely relates to a ball mill cylinder inner liner. Background technique [0002] The ball mill is the key equipment for crushing the material after it is crushed. It is widely used in cement, silicate products, new building materials 52555, refractory materials, chemical fertilizers, ferrous and non-ferrous metal beneficiation and glass ceramics and other production industries, for dry or wet grinding of various ores and other grindable materials . [0003] Ball mill cylinder liner is used to protect the steel plate of ball mill cylinder. The chute at the transfer point of small particle size and powdery materials generally uses high molecular polyethylene liner to achieve the purpose of protecting the body. In the case of a certain impact load, many companies at home and abroad now use 16Mn manganese steel linings, high wear-resistant ceramic linings, vermiculite li...

AI Technical Summary

Problems solved by technology

Due to its superior wear resistance than steel, manganese steel liners are widely used, but they are relatively heavy, inconvenient to replace, and their lifespan is only longer than steel, causing a lot of metal waste during use, so they should be replaced; high wear resistance Ceramic and vermiculite liners are light in weight, good in wear resistance, and easy to replace, but they are expensive and not resistant to impact. They work well at the transfer points of general impact loads, and are prone to cracking and serious damage at some points of greater impact loads. , the frequency of replacement is too high, etc. At present, some domestic and foreign polymer material companies have produced and designed rubber and polyurethane wear-resistant linings. Because of their light weight, easy replacement, good elasticity and impact resistance, they are very popular among mine and wharf maintenance workers. However, due to the defects in formula, structure and design, at the impact resistance points of some ball mills (especially the coarse grinding feed end of mines), under the impact of larger-sized ore and steel balls, there are still low service life and replacement frequency. High phenomenon not only delays production but also brings a lot of waste
