Discharge plate of automatic mill

Abstract

The present invention discloses discharge plate for automatic mill. The discharge dustpan plate includes dustpan plate body comprising casing of carbon steel and in the shape of dustpan, and protective antiwear layer of rubber material covering the inner surface of casing. The present invention has no wear of quartzite on the carbon steel casing, no iron dust contamination of product, high quality of ground quartzite and reduced dustpan plate weight.

Description

technical field [0001] The invention relates to the technical field of an autogenous mill, in particular to an autogenous mill discharge dustpan plate for discharging materials on the autogenous mill. Background technique [0002] As a kind of medium-free grinding equipment relying on the mutual impact, grinding and crushing of quartz sand itself, autogenous grinding machine has the advantages of no medium, large feeding particle size range (up to 600mm), high output, and uniform discharge. Industries, such as the processing of quartz sand, have been widely used. However, in the self-grinding machines currently used by people, the materials used for the parts on it are mostly some steel materials, such as the discharge dustpan board made of ductile iron, not only uses more materials, but also because of its work The characteristics of the board wall are also thicker, resulting in a larger weight of the dustpan board, which is very inconvenient in use and disassembly, and wh...

Problems solved by technology

However, most of the autogenous mills used by people are made of some steel materials, such as the discharge dustpan board made of ductile iron, which not only uses more materials, but also because of its work The characteristics of the board wall are also thicker, resulting in a larger weight of the dustpan board, which is very inconvenient in use and disassembly, and when using this discharge dustpan board to process quartz sand, the dustpan board will be separated from the Quartz sand particles frequently collide and cause wear and tear, resulting in waste, and the iron filings produced by the wear of the dustpan board will be mixed into the processed quartz sand products, which will greatly increase the iron content in the product and affect the product. Cause pollution and affect the quality of the product, and quartz sand is a product that requires a relatively high iron content, so it is necessary to use additional processes and methods to remove these iron filings, which increases the quality of the product to a certain extent. Production costs, reduced production efficiency
