Large-grain-diameter coal coal washery

Abstract

The invention provides a large-grain-diameter coal coal washery. The large-grain-diameter coal coal washery comprises a coal screening device, coal smashing equipment and coal washing equipment. The coal screening device is connected with the coal smashing equipment, and the coal smashing equipment is connected with the coal washing equipment. The coal screening device comprises a screening box, amovable box, a transmission structure, a screening motor, a screening structure, two U-shaped blocks and multiple U-shaped frames. The bottom of the movable box is fixed to the top of the screening box, and the transmission structure is arranged in the movable box. According to the large-grain-diameter coal coal washery, the requirements of screening of coal with different grain diameters are metby adjusting the diameters of screening holes, the comprehensive performance of the screening equipment is improved, screening plates of different types do not need to be prepared for backup, the manufacturing cost of the equipment is reduced, the types of products are increased, the value of the products is improved, and economic benefits are increased.

Description

technical field [0001] The invention relates to the field of coal processing, in particular to a large-diameter coal washing plant. Background technique [0002] Coal is a solid combustible mineral gradually formed by ancient plants buried in the ground through complex biochemical and physical chemical changes. Coal is known as black gold and industrial food. It has been the main energy source used by the human world since the eighteenth century One, since the beginning of the 21st century, although the value of coal is not as good as before, after all, coal is still one of the indispensable energy sources for our human production and life for a long time to come. [0003] In real life, after coal mining, coal needs to be processed in a series, such as crushing, screening and washing, etc. However, there are a lot of shortcomings in the existing crushing and screening equipment, such as the existing coal crushing and screening equipment It cannot meet the screening of coal ...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a coal washing plant with large particle size coal, which solves the problem that the screening of coal with different particle sizes cannot be satisfied, and does not have the function of quantitative crushing, which seriously reduces the effect of coal crushing, and the coal washing is slow, and the washing process is difficult. The problem of poor performance
