[0002] During the production and processing of coal mines, a large amount of solid waste will be generated with the mining and processing of coal mines, including mainly coal gangue. Coal gangue is a kind of black-gray rock with low carbon content and harder than coal that accompanies coal seams during the coal formation process. The processing of coal gangue often involves crushing the coal gangue.

[0004] Although the above invention patent document can crush the coal gangue, a large amount of coal powder will be attached to the surface of the coal gangue. During the crushing process, the flying coal powder will increase the dust volume and also cause the waste of coal powder. Therefore, we propose a coal mine solid waste treatment device to solve the above mentioned problems. Utility Model Content
