Mine crusher

Abstract

The invention discloses a mine crusher. The mine crusher comprises a box body. A water storage tank is arranged at the upper side of the box body. Drain pipes are arranged at the lower ends of the left side and the right side of the water storage tank. A water storage plate is arranged at the lower sides of the drain pipes. A plurality of spray heads are arranged at the lower side of the water storage plate. Charging pipes are arranged at the left end and the right end of the lower side of the spray heads. A flow guide plate is arranged at the upper end of the inside of the box body. Three crushing rollers are arranged at the lower side of the flow guide plate. A tilted filter screen is arranged at the lower side of one crushing roller. First connecting pipes are arranged at the outer side of the tilted filter screen. The outer side of each first connecting pipe is provided with a conveying cavity. The inner side of each conveying cavity is provided with a second connecting pipe. A discharging cavity is formed in the lower side of the tilted filter screen, and discharging pipes are arranged at the left side and the right side of the lower end of the discharging cavity. Grinding cavities are formed in the lower ends of the outer sides of the discharging pipes, and material outlet pipes are arranged at the lower sides of the grinding cavities. An electric cabinet is arranged at the lower end of the right side of the box body. A vibration attenuation supporting device is arranged at the lower side of the box body. A base is arranged at the lower side of the vibration attenuation supporting device. By the adoption of the mine crusher, coal can be effectively crushed, screened and ground, and crushing quality of the coal is guaranteed.

Description

technical field [0001] The invention relates to a mine equipment, in particular to a mine crusher. Background technique [0002] Mining crushers are also called stone crushers, which refer to crushing machines in which the particle size of the discharge is greater than 3 mm and accounts for more than 50% of the total discharge. Invented by the British Hengan. Crushing operations are often divided into coarse crushing, medium crushing and fine crushing according to the size of the feeding and discharging particles. Commonly used gravel equipment includes jaw crusher, impact crusher, impact crusher, compound crusher, single-stage hammer crusher, vertical crusher, gyratory crusher, cone crusher, and roll crusher. Crusher, double roll crusher, two-in-one crusher, one-time forming crusher, etc. [0003] At present, the mining industry usually adopts a single-stage crushing method to produce stones.

Problems solved by technology

[0003] At present, the mining industry usually adopts a single-stage crushing method to produce stones. Not only is it easy to miss the stones in one-time crushing, but also the crushing is uneven. The missed stones need to be put into the crusher again, which wastes human resources and leads to low work efficiency. Low, it is difficult to meet the production needs of the enterprise, and the equipment often or generates a lot of vibration during the working process, which seriously affects the service life of the equipment. In addition, the equipment will generate a lot of dust during the crushing process. will seriously affect the surrounding environment
