The use of equipment will inevitably lead to losses, which in turn will affect the efficiency of the equipment, and the efficiency will become lower and lower. Understand these daily maintenance techniques to extend equipment life and improve efficiency.

1. Understand the working principle of impact crusher: When the impact crusher is working, the rotor is driven by the motor to rotate at high speed. When the material enters the hammer's action area, it collides with the hammer on the rotor, and then is thrown into the counterattack device to break again, and then counterattack. The liner rebounds back to the hammering area and then crushes again. Repeat the process, and repeatedly crush the material into large, sm and sm impact chambers until the material is crushed to the required particle size and discharged from the discharge port.

2. Solving skills It can be seen from the working principle of the impact crusher that in the long-term crushing operation, the wear of the impact crushing cavity is serious. Therefore, in daily maintenance and repair work, you can often check the wear of the hammer, and replace and repair it in time.

(1). In the case of severe wear or fracture, the method of restoration is to use 506 electrode, No. 2 high carbon electrode and No. 5 high tungsten electrode to carry out surfacing test on the worn plate hammer. The anti-impact hammer after surfacing welding with No. 5 high tungsten electrode has the * wear resistance and impact resistance. After surfacing welding with 506 electrode and No. 2 high carbon electrode, the wear resistance of the counterweight is more than 2 times higher than that of the original high manganese steel counterweight. However, these two types of welding surfacing are costly and uneconomical. Therefore, No. 5 high tungsten electrode has good wear resistance and high economic efficiency. The specific method is to use the auxiliary plate to wear 3~5mm. No. 5 high tungsten electrode surfacing 2 to 3 times.

(2). In daily work, the impact angle of the impact crusher can be adjusted. The increase of the impact angle can increase the impact strength and ensure the particle size after the material is broken.

(3). Since the heavy hammer is a more severely worn part, it can be interchanged and reversed in the design of the heavy hammer.

(4). The gap between the rotor of the impact crusher and the front of the casing can be appropriately increased to prevent the front of the body from being blocked, which effectively improves the production efficiency of discharging and reduces the wear of parts.

(5). The front impact plate movable arm of the impact crusher and the rear counter pressure rod are integrated, which improves the elastic vibration of the impact plate, so that the material on the impact plate can be sent to the crusher casing in time to crush the subsequent The materials enter the lower bin together.
