A motor-built-in gangue double-roll crusher

Abstract

A coal gangue roller crusher in the type of a built-in motor includes a box body and two groups of crushing rollers which are arranged in the box body symmetrically. Each crushing roller is mainly composed of a teeth roller, a support wheel, a boat-shaped motor bracket, a supporting rod, a motor, a spring trough, an idle wheel, a driving wheel, a driving axle, a spring, a motor gear, a supporting axle, an idle axle, and a rolling wheel. The coal gangue roller crusher employs double-output explosion-proof motors, wherein two output terminals of the motor are both transmitted to the teeth rollers through gears; meanwhile, the other ends of the crushing rollers are matched with the teeth rollers through the support wheels; finally, the supporting rods, extension rods, the supporting axles and the like and the motor gears, the idle wheels, the driving wheels and the like are all installed on the boat-shaped motor brackets, the boat-shaped motor brackets are then fixed onto the box body. The coal gangue roller crusher saves space, simplifies power transmission during rolling processes, reduces cost of exploitation and transportation, provides low-cost raw materials for underground filling, and has strong innovativeness and wide practicability.

Description

technical field [0001] The invention relates to a coal gangue selective crushing equipment, especially a motor-built-in coal gangue double-roll crusher, which is especially suitable for the selective crushing process of materials in coal and gangue separation processes in coal mines or in narrow space areas. It is suitable for the selective crushing process of two materials with large differences in hardness. Background technique [0002] Waste rock is an accompaniment to coal mining. The traditional waste rock treatment method is to transport it from underground to the ground and accumulate it to form gangue hills. The existence of these waste rock hills has brought many adverse effects to the environment of the mining area and polluted the surrounding environment. To effectively solve the accumulation and pollution problems of gangue, we should start from the source of gangue production and process gangue underground. The key is to separate coal and gangue. [0003] The t...

Problems solved by technology

[0004] However, the existing double-roll crushers still have problems such as large volume, large space occupied by motors, racks and other equipment, and complicated power transmission of the crushing rollers. Moreover, the driving devices of the existing double-roll crushers all use external motors. , driven by a belt, not only increases the size of the equipment, but also has poor transmission effect, so it is not suitable for coal gangue separation in coal mines with narrow space
