Welcome to China First Enginnering Technology Co.,Ltd
1. The normal operating temperature of the bearing box of the sand making machine is 40℃ ~ 60℃, and the maximum allowable temperature is 70℃. After running for half an hour, if the temperature exceeds 70℃, there is a certain problem in the bearing box, and it should be shut down for maintenance.
2. When the sand making machine is under load, the feeding size should not exceed the maximum size allowed by the equipment.
3. During the initial feeding of the sand making machine, there is usually an unbalanced process of about 30 ~ 60s. In this case, the feeding cannot be stopped, and the feeding amount should be increased as much as possible until the vibration is reduced. When feeding particles are large, intermittent vibration will occur, and it will return to the normal state after a few seconds. This is a normal situation caused by a stone's throwing head retaining the stones, which is caused by accumulation and then washed away. There is no need to be nervous.
4. The vibration intensified during the operation of the sand making machine, which indicates that there may be non-uniform wear between the wear parts and the rotor, which is caused by the unbalanced state caused by the non-uniform rotor and the accumulation of material, or the loosening of the cone of the pulley. . After the normal vibration is eliminated, the machine can be stopped for inspection. In addition, a vibration switch installed on the sand making machine can be set, and when it detects unbalanced vibration, it actively stops before equipment damage and personnel injury occur.
5. The wear-resistant parts of the rotor of the sand making machine are designed to protect the rotor body from abrasion. In order to ensure trouble-free operation of the sand making machine, the inspection of the wear-resistant parts of the rotor and the internal material lining of the machine must be brought into the routine, and the wear parts that cannot meet a work shift should be replaced in time. Every 8-10 hours of equipment operation, the inside and appearance of the rotor and the sand making machine should be checked, and the bearing box should be filled with grease, etc.
6. Check the current of the sand making machine motor. If the motor current is too large and the motor is overloaded, the feed amount should be reduced until the current value is normal.
At present, the price of sand and gravel is soaring. Stone factories should pay more attention to the reasonable use and maintenance of sand making machines, so that the equipment can continue to operate normally, improve the service life of the equipment, ensure the efficient operation of equipment, and increase corporate profits.
