Abstract

The invention relates to a crushing device for coal gangue separation. The crushing device comprises an outer cover, a material separating device, a plurality of guide plates, a material throwing tray and a bracket, wherein the outer cover is fixed on the bracket; a feeding hole is formed in the top of the outer cover; the bottom of the outer cover is provided with a discharge hole; a vortex bin is arranged in the middle of the outer cover; the material separating device is arranged in the feeding hole and the vortex bin; the upper part of the material separating device has an umbrella-shaped structure; a feed opening is formed in the top of the material separating device; a coal gangue storage bin is arranged in the middle of the material separating device; the material throwing tray is arranged under the material separating device; the plurality of guide plates are respectively arranged under the umbrella-shaped structure of the material separating device and fixed on the outer cover. The crushing device can be used for selectively crushing coal components in the coal gangue while maintaining the integrity of the gangue component, thus meeting the requirement of separation.

Description

technical field [0001] The invention belongs to the field of solid waste treatment and resource utilization equipment, and in particular relates to a crushing device for sorting coal gangue, in particular to sorting out components with higher coal content in coal gangue after crushing, so as to realize Resource utilization of coal gangue. Background technique [0002] There are more than 1,500 gangue dumps in state-owned coal mines across the country, with an accumulation volume of more than 3 billion tons. A large number of piles of coal gangue will not only occupy the land and affect the ecological environment, but the gangue leaching water will pollute the surrounding soil and groundwater, and the coal gangue contains certain combustibles, which will spontaneously combust under suitable conditions and emit sulfur dioxide and nitrogen oxides. Harmful gases such as carbon oxides and smoke pollute the atmospheric environment and affect the health of residents in mining area...
