Composite grate plate for automatic mill

Abstract

The present invention discloses composite grate plate for automatic mill. The composite grate plate includes grate plate with conic discharge holes for sieving ground material, and netted support covered with elastic antiwear layer. The present invention has no waste of worn expensive material, no iron dust caused by wearing steel material, and high quality of ground quartzite.

Description

Technical field [0001] The invention relates to the technical field of a self-grinding machine, in particular to a composite grating board for a self-grinding machine. Background technique [0002] As a non-medium grinding equipment that relies on the mutual impact, grinding and crushing of materials, the self-grinding machine has the advantages of no medium, large feeding size range (up to 600mm), high output, uniform discharge, etc., in the ore processing industry , Such as quartz sand processing has been very widely used. However, the self-grinding machines currently used by people are mostly made of expensive special steel materials, such as manganese steel grid plates. The grid plates using this material are used for quartz sand. During processing, the self-grinding machine not only has a higher dead weight, but also increases the working strength of the self-grinding machine drive device. Also, when frequent collisions with quartz sand ore cause wear, the manganese steel sc...

Problems solved by technology

However, most of the autogenous grinding machines used by people are made of expensive special steel materials, such as manganese steel grid plates, which are used in the grinding of quartz sand. During processing, not only the self-weight of the autogenous mill is relatively large, which increases the working strength of the driving device of the autogenous mill, but also when it frequently collides with quartz sand ore and causes wear, the manganese steel chips produced by the wear of the grid plate will be mixed with Into the processed quartz sand products, it will pollute the product and affect the quality of the product, and most of these mixed manganese iron and steel shavings cannot be removed by the subsequent magnetic separator, so that the iron in the product The quantity is greatly increased and the quality of the product is reduced

Quartz sand products have relatively high requirements on iron content, which requires other processes and methods to remove these manganese iron and steel shavings, which increases the production cost of the product to a certain extent and reduces the production efficiency.
