Grinding body blocking preventing grid plate

Abstract

The invention discloses a grinding body blocking preventing grid plate. The grinding body blocking preventing grid plate comprises a combined plate; a plurality of grid seams are arranged on the surface of the combined plate, and a plurality of mounting holes are distributed in the upper part of the combined plate; the grate seams comprise material channels, one sides of the material channels areprovided with material outlets, and the other sides of the material channels are provided with material inlets; asymmetric chamfering structures are arranged on one side walls of the material inlets,and first port side wall rolling ball sets are arranged at the vertical side walls of ports of the material inlets; port middle rolling ball sets are arranged in the middles of the front walls and therear walls of the ports of the material inlets, and second port side wall rolling ball sets are arranged at the inner walls of the chamfering structures of the material inlets; and the first port side wall rolling ball sets, the port middle rolling ball sets and the second port side wall rolling ball sets are correspondingly provided with a plurality of rolling balls. According to the grinding body blocking preventing grid plate, through the operation of a tube mill, so that a grinding body clamped in the gap of the grid plate can be smoothly separated out of the grid seams under the impact action of the material.

Description

Technical field [0001] The invention relates to the field of parts of a tube mill, in particular to an anti-grinding body to block a grate plate. Background technique [0002] At present, in the production process of cement and other building materials industry, the tube mill is the main equipment for cement grinding and is used in many production lines. After years of use and improvement, the technology of the tube mill itself has been relatively mature, but in the actual use process Inevitably, you will encounter some problems. During the operation of the tube mill, due to the influence of wear and thermal expansion, many grinding bodies will get stuck in the grate. When entering the tube mill for inspection, it was found that many balls, forgings and their broken bodies blocked the grate seams of the partition plate grate and the discharge grate, which greatly affected the pass rate and ventilation effect of the mill. This will affect the production capacity of the mill. [0...

AI Technical Summary

Problems solved by technology

When entering the tube mill for inspection, it was found that many balls, forgings and their broken bodies blocked the grate gaps of the compartment plate and the discharge grate plate, which greatly affected the passing rate and ventilation effect of the mill. Then affect the production capacity of the mill

[0003] Aiming at the above problems, the Chinese patent No. CN201721092146.9 proposes an anti-blocking grate plate that basically solves the problem, but in practice, there are still some deficiencies in this solution: although one side of the feed port is set as an asymmetrical chamfering structure , but the grinding body stuck in the gap of the grate plate is not smooth out of the gap under the impact of the material, and it is often stuck in it
