The coal gangue crusher can be used to crush gangue, coal slag, shale, slag, slag, ore, coal slurry, sludge, construction waste and other products. The fineness can be below 70% to 2mm, and 90% of the finished products are below 3. Using coal gangue, coal slag, and furnace slag as additives and internal fuels for brick factories; Producing standard bricks and hollow bricks from gangue and shale is a major measure that complies with national policies and benefits society. But the crushing problem of these materials, especially wet materials, has always been a difficult problem for brick factories to produce normally. This coal gangue crusher is suitable for use in large, medium, and small brick factories, coal washing plants, slag factories, coal mines, and other industries. The coal gangue crusher has been continuously improved and innovated based on the old coal gangue crusher, forming a series of new coal gangue crushers for production.

Structure of coal gangue crusher

This machine is mainly composed of components such as frame, rotor, lining plate, hammer head, etc., and is driven by groove wheel. The material is crushed due to the impact of the high-speed rotation of the rotor and the hammer head with the animal material on the crushing plate. The rack is divided into two parts: the upper body and the lower body. The machine cavity is equipped with wear-resistant protective lining plates to protect the wear and deformation inside the body. The rotor consists of rotor shaft, middle disk, end disk, hammer shaft, hammer head and other components.

Working principle of coal gangue crusher

When the coal gangue crusher is in operation, two sets of rotors connected in series rotate at high speed under the drive of the motor. The material is immediately crushed by the hammer head of the rapidly rotating lower rotor in the machine cavity after being crushed by the upper rotor. The materials in the cavity collide and crush each other at high speed, achieving the effect of hammer powder and material powder, forming coal slag particles with a discharge particle size of less than 3 millimeters. This particle size can fully meet the requirements of brick and tile manufacturers as internal combustion bricks.

1、 Double rotor two-stage crushing, high output, with a particle size of less than 3mm and more than 80% below 2mm: two sets of rotors connected in series, so that the material crushed by the upper rotor is immediately finely crushed again by the hammer head of the lower rotor that rotates rapidly. The materials in the inner cavity collide and crush each other at high speed, achieving the effect of hammer powder and material powder, and are directly discharged

2、 Without a sieve bottom, high humidity materials will never block traditional crushers with sieve plates. They are not suitable for raw materials with a moisture content higher than 8%. When the moisture content of the raw materials is higher than 10%, serious blockage is prone to occur, causing the hammer head to not rotate, the material to not be discharged, and even burning out the motor, seriously affecting production.

The design of the coal gangue crusher does not have a sieve bottom, and there is no strict requirement for the moisture content of the material. There is no problem of clogging the sieve plate, and there is no problem of fine powder not being discharged in a timely manner and repeated crushing. Therefore, the crushing efficiency is high and there is no ineffective wear of the hammer head.

3、 Double stage dual flying wheels, smooth operation with high inertia, saving 20% electricity. The coal gangue crusher device has a balancing device, which makes the machine operate more stably, saves bearings and high-speed shafts, and saves 20% of electricity. In addition, it enhances the strength of the hammer head, resulting in an increase in production.

4、 Wear resistant combination hammer head, unique displacement gap adjustment technology: high alloy wear-resistant hammer head. Hammer head and handle combination use, only replace the hammer head, not the handle. After the hammerhead wears out, it does not need to be repaired. It can be moved and reused repeatedly. One set of hammerheads can support three sets of hammerheads.

5、 Centralized lubrication system, timely lubrication without stopping, convenient and fast. The lubrication system of the coal gangue crusher adopts centralized oil injection, which can be injected without stopping the machine during normal operation. Multiple oil supply can be operated in one step without affecting the work at all.

6、 Hydraulic opening and closing of the casing saves time and labor in hammer replacement and maintenance: operated by an electric oil pump, the opening and closing can be controlled freely, and the directional oil valve can be changed, which has changed the major safety hazard that the manual pressure pump could not pull before, making it safer for users during use and maintenance. The coal gangue crusher adopts hydraulic starter housing technology, which allows one person to easily open the housing, making maintenance and inspection of parts convenient and fast.
