The particle size of the finished product of the general metal crusher is produced according to user requirements. Because the steel smelting industry has high requirements for material accuracy, if you want to sell it at a good price, the finished particles must be clean and free of impurities, but also have a uniform size. After the metal crusher is used for some time, the particle size of the finished product will be uneven, which does not meet the material recovery standard. Therefore, whether the particle size of the finished product processed by the metal crusher meets the requirements is very important! Today Yingde editor is here for Everyone introduces the five methods to ensure the uniform size of the finished metal crusher
1. The speed of the metal crusher
The speed of the metal crusher is controlled by the motor driven by the pulley. However, after long-term operation of the metal crusher, the belt that drives the metal crusher will become loose, which causes the main shaft speed of the equipment to slow down, resulting in The problem of large material particle size, so we should check and maintain it regularly. If this problem occurs, replace the V-belt immediately to avoid uneven particle size of the metal crusher.

2. Hammer head wear
The hammer is an important part of the metal crusher. During the operation, the hammer is mainly used to hit the material to achieve the crushing effect. If the hardness of the material is too large, the hammer will be damaged and the hammer will be severely worn. Otherwise, it will not be able to play its due role, and accordingly, the output particle size will be too large. In view of this situation, timely replacement of the hammer head can ensure the normal operation of the metal pulverizer, and the discharge particle size reaches the standard; remember: when assembling or replacing the hammer head, the balance of the rotor must be maintained. The total weight of the hammer heads on each row of hammer shafts should be equal to the total weight of the hammer heads on the corresponding hammer shafts, the total deviation should not exceed 100g, and the weight deviation of a single hammer head should not exceed 0.5kg.

3. Sieve aperture size
The finished products flow out through the screen, so the larger the aperture, the larger the finished product, and of course the larger the output; the smaller the aperture, the smaller the finished product, and the output will be greatly reduced. After the metal crusher is used for a period of time, the screen will be worn to a certain extent, and the pore size will appear uneven, which will affect the size of the finished product, so the screen should be replaced regularly.

4. The gap between the bottom of the screen becomes larger
After the metal crusher is used for a period of time, the vulnerable parts (breaking hammer, screen) will be worn to a certain extent, which will cause the gap between the crushing hammer and the bottom of the screen to be too large, which will make the particle size of the finished product uneven. In this case, the gap between the hammer head and the screen bar can be adjusted by rotating the eccentric shaft, or by changing the screen bar style, or inserting packing blocks at both ends of the screen bar installed in the screen bar holder slot to change the screen bar Gap.

5. Feeding and discharging of metal crusher
The control of the particle size of the metal crusher should start from the feed, and the constant feed is the key to ensure the correct feeding speed; secondly, the discharge port of the metal crusher is also the key part that needs to be controlled. It should be ensured that the discharge port is unblocked and carried out regularly. clean up.
