  • What are the reasons that affect the output of high pressure grinding mill?
    high pressure grinding mill

    1. The powder lock of the high pressure grinding mill production line cannot collect materials normally.
    The possible reason is that there are some problems with the tightness of the powder lock, which causes air leakage, which makes the ground finished product suck back and cannot be collected normally. The solution in unobstructed situations is to conduct an overall inspection of the tightness of the powder locker and make appropriate adjustments to increase the amount of powder collected by the powder locker.

    2. Too much material supply caused the air duct device to become blocked.
    The air duct is the main channel for the airflow operation of the entire equipment, and it is related to whether the entire equipment can run smoothly. The blocked air duct will cause the entire airflow to heat up due to poor exhaustion. At the same time, it will affect the temperature of the motor, increase the temperature of the motor, reduce the motor current operation at high temperatures, insufficient power supply, and insufficient operating power of the equipment, which will affect the overall output. The solution to this situation is mainly to adjust the feeder to appropriately reduce the amount of material input, and at the same time clean the pipeline to remove the powder accumulated in the pipeline. In addition, the valve at the air pipe can be properly opened. Larger, control the temperature of the material and ensure that the temperature of the supplied material is not too high, and the temperature of the feed generally does not exceed 6 ° C.

    3. The internal shovel blade of the main machine is worn, and the material cannot be shoveld in time.
    As a result, some of the material cannot be ground, and the grinding amount of the material is reduced, resulting in a relatively reduced final output. For the solution to this situation, the wear degree of the blade can be checked regularly, the blade that needs to be replaced should be replaced in time, and the output of the material should be observed in time to solve the problem in time.

    4. The analysis machine works abnormally, and the blades of the analysis machine may be worn at different degrees during long-term operation, and cannot perform the classification of materials. The materials cannot be effectively classified, and effective materials cannot be sorted, which affects the output. The solution is to regularly check the blades of the analyzer, replace the damaged blades, and adjust the air volume of the fan appropriately to reduce the air intake.

    5. The grinding rings in the grinding chamber are severely worn.
    The grinding roller grinding ring often grinds hard materials. In the case of long-term use, it may cause its shape to be worn to varying degrees, which affects the grinding effect. The working performance of the damaged parts is greatly reduced, and the material output is affected. In this case, you can regularly check and replace the grinding roller grinding ring, and pay attention to cleaning the inside of the host in time.

    6. The overall airflow of the equipment is not stable, and the airflow volume is not adjusted.
    The airflow volume of the fan is an important link affecting the material collection. A reasonable airflow volume of the fan can make the production run smoothly. The problem can be solved by adjusting the air intake of the fan.

    7. The wind blade of the fan is worn, and powder may be deposited on the blade, which causes the wind blade to fail to operate normally and affects the final output. The solution is to check the degree of wear of the blade, and it needs to be replaced in time to clean up the powder particles attached to the surface of the blade. Pay attention to check whether the blade is clean in daily operations and remove the powder on the blade in time.

    8. The upper bearing of the main engine is short of oil, which affects the operation of the whole machine.
    There may be problems with the quality of the oil used. If the oil viscosity is too large or too thick, the thread pump oil cannot deliver the oil to the upper bearing, the bearings cannot be lubricated in time, the working efficiency is reduced, and the grinding output is affected. Solution: Check the quality of the motor oil used, and select a motor oil with a moderate viscosity and thickness.

    9. The host runs unevenly and affects the use effect.
    The anchor bolts may be loose. The solution: Check the bolts in time and find that the anchor bolts are loose and tightened. The material conveying volume is too small, and the final output is affected. Solution: You can check the feeding amount of the equipment, adjust the feeding device, adjust the supply amount of the material to an appropriate range, and increase the feeding amount reasonably.

    There are many factors that affect the output of a high pressure grinding mill. If the problem of low output is found, scientific and reasonable inspection can be performed on each part of the equipment to find the cause of the problem. Sometimes there may be multiple problems at the same time. This requires related technical personnel to pay attention to the maintenance of the high pressure grinding mill and replace the wearing parts in time, which can effectively guarantee the production performance of the equipment and ensure the output.
