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 product

Example Embodiment

[0017] Refer to Figure 4 In the figure, the grating plate 7 currently used is installed at the discharge end of the grinding cylinder 3 of the self-milling machine. The grating plate 7 is arranged in the circumferential direction of the grinding cylinder 3 to divide the grinding cylinder 3 into a material self-grinding space and row. In the discharging space, there are several dustpan plates 4 arranged along the circumference of the grinding cylinder 3 that can transport the quartz sand particles screened by the grating plate 7 to the discharge cylinder 5, because the grating plates currently used by people Most of the discharge holes are strip-shaped holes. There are some larger quartz sand particles in the quartz sand screened by the grid plate with strip-shaped discharge holes, so there is a self-returning screen in the discharge barrel 5. 6. The self-returning sieve 6 can transport the larger quartz sand particles back to the grinding cylinder 3 for self-grinding, while the s...

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...
