The impact type coal crusher uses the principle of impact crushing to smash the materials. It is a crusher equipment that is finer than the jaw type coal crusher. It is mainly used for fine crushing operations in the stone production line, and cooperates with the jaw type coal crusher. broken. Coal crusher is an indispensable equipment for stone production line and sand production line. It has the following advantages in the process of crushing:
1. The coal crusher does not block and the crushing capacity is large:
The coal crusher is more effective in processing materials with a large amount of moisture, and effectively prevents material clogging. When the water content of the material is too large, the feed chute and impact plate of the coal crusher can be equipped with a heating device to prevent the material from sticking. The coal crusher does not need to be equipped with a bottom sieve plate, which can effectively prevent clogging.
2. The hardness of the materials crushed by the coal crusher is relatively wide:
The plate hammer of the coal crusher is firmly fixed on the rotor by a mechanical clamping structure, and has a large moment of inertia when rotating with the rotor. Compared with the hammer crusher (the hammer head is in a suspended state), the rotor of the coal crusher has greater momentum, which is suitable for crushing harder materials, and at the same time, the energy consumption is lower.
3. The coal crusher can easily and flexibly adjust the discharge particle size, and the adjustment range is wide.
The coal crusher can adjust the discharge particle size in various ways, such as adjusting the rotor speed, adjusting the gap between the impact plate and the grinding chamber, etc. The gap adjustment can be adjusted mechanically or hydraulically. The hydraulic adjustment system can easily adjust the gap through the local operation button or the travel control system.
4. The wearing parts of coal crusher are less worn and the metal utilization rate is high
The wear of the blower of the coal crusher only occurs on the side facing the material. When the rotor speed is normal, the feed material will fall to the surface of the blow bar (strike surface), and the back and sides of the blow bar will not be worn. Even the side facing the material suffers very little wear. And the bottom grinding bar is also easy to replace. The metal utilization rate of the blower of the coal crusher can be as high as 45%-48%.
5. The replacement of spare parts of the coal crusher is simple and the maintenance cost is reduced accordingly
There are only 6 blow bars installed on the rotor of the coal crusher. The blow bars can be easily replaced with special tools designed by Huacheng Heavy Industry. It only takes one shift to replace a set of blow bars. The replacement of the grinding rod in the bottom grinding chamber only takes tens of minutes, which greatly reduces the time and cost of inspection and maintenance.
