Description

Technical Field

[0001] The utility model relates to the technical field of gangue screening, and more specifically, to a new type of smash-resistant screen plate for gangue de-mediating screen. Background Art

[0002] The sieve plate of the gangue de-mediating screen in the lump coal workshop is a 610mm*610mm*2.0mm polyurethane-edged stainless steel flat sieve plate. All the 200-13mm gangue blocks sorted by the shallow trough sorter are transported away after the medium on the surface of the gangue is recovered by the de-mediating screen. In production, due to the large amount of gangue and the high hardness of the gangue in the 3-5 coal seams, the wear and impact on the screen plate are also large. Once the screen plate breaks on a large scale, gangue larger than 2mm will enter the medium barrel or block the magnetic separator pipeline, affecting normal production. In particular, the screen plate at the feed end is hit the hardest and is easily damaged, resulting in frequent replacement and high work intensity for charter maintenance personnel. Based on this, the utility model designs a new type of smash-resistant screen plate for gangue de-mediating screen to solve the above problems. Utility Model Content
