Coal processing equipment for coal mines

Abstract

The invention discloses coal processing equipment for coal mines, and belongs to the technical field of coal processing equipment. The coal processing equipment comprises a coal crushing and screeningmechanism, a screening cabinet, a grinding table, a conveyor belt and a coal grinding mechanism; the coal crushing and screening mechanism comprises a coal crushing assembly, a secondary crushing assembly, a reciprocating vibration assembly, an upper separation net and a lower separation net; the screening cabinet is internally provided with a dust removal assembly, and a feeding channel communicating with the interior of the screening cabinet is formed in the top of the screening cabinet; and two discharging channels are formed in the left side of the screening cabinet, and the discharging channels communicate with the interior of the screening cabinet. The coal processing equipment has the beneficial effects that coal can be automatically crushed at multiple stages through the coal crushing and screening mechanism, the upper separation net and the lower separation net can vibrate intermittently under the effect of the reciprocating vibration assembly, the situation that the upper separation net and the lower separation net are blocked is avoided, and generated dust can automatically fall through the dust removal assembly.

Description

technical field [0001] The invention relates to the technical field of coal processing equipment, in particular to coal processing equipment for coal mines. Background technique [0002] Coal is hailed as black gold and the food of industry. It has been one of the main energy sources used by the human world since the eighteenth century. Since the beginning of the 21st century, although the value of coal has dropped significantly, after all, the present and the future are very long. For a period of time, coal is still one of the indispensable energy sources for our human production and life. The supply of coal is also related to the stability of the development of my country's industry and even the entire society. The issue of coal supply security is also the most important aspect of my country's energy security. important part. Coal needs to be crushed after excavation and before use, and then further crushed into coal particles of suitable size according to needs; currently,...
