Coal gangue impact 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 impact crusher.

1. Composition and structure

Impact crusher mainly consists of body, inlet, liner, tie rod, impact plate, rotor frame, plate hammer, discharge port.

2.Working Principle

The impact crusher utilizes the impact energy to crush the gangue material, the motor drives the rotor to rotate at high speed, the gangue material enters the plate hammer area and crushes with the plate hammers on the rotor, and then it is thrown to the counter-attack device to be crushed again, and finally returns to the plate hammer area to be crushed again, through the cycle of continuous impact and crushing, the gangue material is crushed until it reaches the required granularity, and then it will be discharged from the discharge port.

3.Operation Advantages

(1) The machine has novel structure, compact combination, large production capacity, large impact force and high compressive strength.

(2) The discharge size of the machine is small, the finished material is cubic granular, complete shape, good particle size.

(3) The machine can control and adjust the gap between the counterattack frame and the rotor in the process of operation, which is easy to adjust and can change the granularity and shape of the material.

(4) The machine has a large feed opening and high crushing cavity, which makes the machine highly efficient and energy-saving.

(5) The wearing parts of the machine are all made of high-end materials, and the plate hammer is made of high chromium, which is resistant to impact and abrasion, and has a longer service life.

(6) The machine produces less stone powder during operation, no environmental pollution, and low noise.

(7) The overall size of the machine is small, small footprint, easy to install and move.
