Six Operation Points Of Sand Making Machine

With the limited exploitation of natural sandstone, there is an increasing demand for sand and gravel in the market. As the most important equipment in the artificial sand production line, the sand making machine has been invested by more and more customers. However, many customers do not know how to operate the sand making machine in the actual production. Here are some operation tips for the sand making machine.

1. The normal operating temperature of the bearing box of the sand making machine is 40 ℃ ~ 60 ℃, after half an hour of operation, if the temperature exceeds 70 ℃, it indicates that there are some problems in the bearing box, and it should be shut down for maintenance in time.

2. When the sand making machine is under load operation, the feeding particle size shall not exceed the particle size allowed by the equipment.

3. During the initial feeding of the sand making machine, there is usually be an unbalanced process of about 30 ~ 60s. In this case, the feeding cannot be stopped, and the feeding amount shall be increased as much as possible until the vibration is reduced. When the feeding particles are large, there will be intermittent vibration, which will return to normal state after a few seconds. This is the normal situation caused by a certain throwing head of the rotor retaining stones, forming the accumulated materials and being washed away without tension.

4. During the operation of the sand making machine, the vibration intensifies, which indicates that there may be non-uniform wear between the wear-resistant parts and the rotor, which is caused by the unbalanced state caused by the non-uniform rotor and the accumulated material, or the loose cone sleeve of the belt pulley and other reasons. After the normal vibration is eliminated, the machine can be stopped for inspection. In addition, the vibration switch installed on the sand making machine can be set. When it detects the unbalanced vibration, it will shut down the machine before equipment damage and personal injury.

5. The rotor wear-resistant parts of the sand making machine are designed to protect the rotor body from wear. In order to ensure the trouble free operation of the sand making machine, it is necessary to include the inspection of the rotor wear-resistant parts and the internal lining of the machine into the routine, and the worn parts that can not meet the requirements of a work team should be replaced in time. Every 8-10 hours of operation of the equipment, the internal and external appearance of the rotor and sand making machine shall be inspected, and the bearing box shall 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, reduce the feeding amount until the current value is normal.
