With the limited mining of natural sand and gravel, municipal engineering is still in full swing, and there is an increasing demand for gravel in the market. Machine-made sand is becoming more and more people’s favorite. However, many customers don’t know how to operate the sand making machine in practice. Today, I will share with you the key points of the use of the sand making machine and the professional scientific name of the accessories.
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 half an hour of operation, if the temperature exceeds 70℃, it indicates that there is a certain problem with the bearing box, and it should be shut down for maintenance in time.
2. When the sand making machine is running under load, the feeding particle size is not allowed to exceed the maximum particle size allowed by the equipment.
3. During the initial feeding of the sand making machine, there will usually be 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 drops. When the feed particles are large, it will produce intermittent vibration, which will return to the normal state after a few seconds. This is due to the normal situation caused by the accumulation of materials and then being washed away after a certain throwing head of the rotor retains stones. nervous.
4. Vibration intensifies during the operation of the sand making machine, indicating that there may be uneven wear between the wear-resistant parts and the rotor, which is caused by the unbalanced state caused by the non-symmetrical rotor and the accumulation of materials, or the looseness of the cone sleeve of the pulley. . After the normal vibration is eliminated, the machine can be shut down for inspection. In addition, the vibration switch installed on the sand making machine can be set, and when it detects unbalanced vibration, it will take the initiative to shut down before equipment damage or personal injury occurs.
5. The rotor wear-resistant parts of the sand making machine are designed to protect the rotor body from abrasion. In order to ensure the 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 included in the routine, and the wear parts that cannot meet the requirements of a work shift should be replaced in time. Every 8-10 hours of operation of the equipment, check the interior and appearance of the rotor and sand making machine, and add grease to the bearing box.
6. Check the current of the sand making machine motor. If the motor current is too large and the motor is overloaded, the feeding amount should be reduced until the current value is normal.
