This unit has a main unit and an auxiliary unit. Integrate the pipeline and the electrical control device into one group. The auxiliary machines include cyclone and bag dust collectors. The main unit is equipped with a centrifugal classification device, which can not only complete the crushing but also has the classification function. It is a sorting centrifugal shearing type, without screens or nets. The powder and particles can be adjusted at will. After the material is crushed, it is conveyed through the discharge valve outlet under negative pressure. Meeting the requirements of the products, this unit is used in the pharmaceutical industry. Ideal machinery for the food and chemical industries.
The interior of the machine has been treated. If it has been left idle for a long time or transported over long distances, the upper cover of the main unit must be opened before starting the machine to check if there are any foreign objects inside. If there are any foreign objects, they must be carefully handled to prevent iron filings from mixing into the product. During the cleaning process, pay attention to whether there are any discarded items inside the machine. If there are any foreign objects, they should be thoroughly removed.
After the main unit is installed, the crushing disc, the main motor with a capacity of 22 kilowatts and the classification motor with a capacity of 4 kilowatts should be rotated by hand in a quiet environment to check if there is any collision inside the machine. Abnormal sounds such as friction.
Check the rotation directions of all motors in the unit. It should be noted that the crushing disc and the classifier should rotate counterclockwise simultaneously. It is strictly forbidden to rotate in opposite directions.
This machine can operate without load. When running without load, the fan must also operate simultaneously. After the main unit has been running for 30 minutes, stop it and check whether the temperature rise of all moving parts of the main unit, especially the bearings and labyrinth seal parts, is within 20 degrees of normal temperature. If there is obvious heating, the cause should be identified and eliminated before normal production can be resumed.
