Description
[0001] This application is a divisional application whose application number is 2016102382813 and the title of the invention is a high-efficiency special crushing device for coal mines. technical field [0002] The invention relates to the technical field of coal mine equipment, in particular to a high-efficiency special crushing device for coal mines. Background technique [0003] The coal sample must be crushed to the specified small particle size before the full water, precision measurement and bias test can be carried out. However, the crushing efficiency of existing crushing devices for coal mines is low, and it is difficult to clean coal samples sticking to them, which cannot meet the demand well. [0004] Therefore, it is necessary to provide a new technical solution to solve the above technical problems. Contents of the invention [0005] The object of the present invention is to provide a high-efficiency special crushing device for coal mines that can effectively...
