Description

(1) Technical field

[0001] The invention relates to a coarse coal slime separation process in a coal preparation plant, in particular to a coarse coal slime separation device and a process thereof. (2) Background technology

[0002] Coal is the main energy source in my country, and currently accounts for about 70% of primary energy in my country's energy structure. Coal's dominant position in my country's energy structure will not change for a long time to come. With the improvement of coal mining mechanization and automation, the content of coal slime in my country's coal is increasing, especially the 1-0.25mm particle size coarse particle separation technology has become a new challenge for the coal preparation industry.

[0003] The main characteristics of coarse-grained coal slime are large content and poor selectivity. Conventional coarse coal slime separation process includes TBS separation, spiral separator separation, coal slime dense medium separation, etc. Among ...
