Coal gangue single section crusher
Coal gangue is a kind of solid waste discharged in the process of coal mining and coal washing, which is a mixture of carbonaceous, muddy and sandy shale, with the color of black and gray. The composition of gangue is mainly silicon, aluminum, calcium, magnesium, iron oxide and some rare metals. It is suitable for building materials, chemical industry, energy, electric power and other industrial sectors. Crushing gangue can choose single-section crusher.
1. Composition and structure
Single-section crusher is mainly composed of rotor, grate bar, striking plate, rolling bearing, hammer head, flywheel, driving part, casing and other components.
2.Working principle
The gangue material enters into the crushing chamber from the feeding equipment, the hammer head runs in the gap of the intermediate bracket and crushes the material continuously, which is the preliminary crushing of the material. The material moves downward and crushes again between the rotor and the bearing plate, and then it is shunted by the bearing plate and enters the discharge area, and finally crushes in the lower crushing cavity formed by the grate and rotor, and discharges the material after the grate plate equalizes the compartments and completes the crushing operation.
3.Operation Advantages
(1) The machine has a reasonable structure, simplified and upgraded process, changed the three-stage crushing to one-stage crushing, and improved the production efficiency.
(2) The machine allows large feeding size, adjustable discharge size range, large crushing ratio, excellent and complete particle size.
(3) The hammer head and grate plate of the machine are made of composite materials with high level, which saves maintenance cost and ensures smooth and stable discharging, and prolongs the service life of the machine.
(4) The machine adopts the crushing cavity modification, which can effectively reduce the wear and tear of wearing parts, and the equipment operation and maintenance costs are low.
(5) The overall power of the machine is small, low power consumption, production costs are greatly reduced.
(6) The machine combination is compact, the overall body is small, covers an area of small, easy to move the site, convenient operation.
