There are two types of common high wear-resistant coal bunker linings: one is that the wet pulverized coal is first bonded on the silo wall, layer by layer, and finally the shape of the rat hole is formed in the silo, and then the coal is loaded. It will cause blockage; the other is due to the large internal frictional resistance between the wet coal powder blocks, and the external frictional resistance between it and the wall is also large. When the coal bunk is filled with coal, the lower taper section of the coal outlet It forms an arched shape similar to stuck and rust (commonly known as bridge). Only a small part of the coal can be placed when the brakes are opened, and the upper coal is blocked by the arching.
In coal mining enterprises in the cold regions of the north, if the cold-proof measures are limited in winter, it is prone to blockage caused by the freezing of water-containing materials and warehouse walls.
High wear-resistant coal bunker liner blocking the consequences:
In order to solve the problem of bonded jamming for many years, people also think of many methods: such as tiling on the wall of the warehouse, laying steel plates, hitting with air cannons or electric hammers, they have not been completely solved, and the artificial coal bunker is often Causing personal injury or death.
