How to control the feeding of sand making machine

Before starting the sand making machine, check the vortex chamber to see if the door is closed tightly. Check the direction of the impeller rotating wheel in the direction of the inlet. During the operation of the sand making machine, the impeller does not rotate counterclockwise, and the motor wiring needs to be adjusted.

The particles supplied by the sand making machine shall be strictly in accordance with the specified requirements, and materials with a particle size larger than the specified requirements shall be prohibited from entering the equipment. Otherwise, the impeller will be unbalanced, the impeller will be severely worn, the impeller passage will be blocked, and the sand making machine may not work normally.

When we stop the discharge equipment of the sand making machine, we need to stop the supply in time to avoid the consequences of crushing the impeller or burning the motor. At the same time, we must regularly shut down the sand making machine equipment, paying special attention to the degree of wear of the central feed pipe, impeller, cone cap, circumferential guard plate and wear block.

The artificial sand powder content control of the sand making machine is mainly realized by two methods:

1. On the premise that the raw materials are clean, reduce the amount of flushing water entering the spiral classifier in the sand making machine workshop and the screening workshop, and reduce the content of fine sand and stone powder that is lost along the water at the tail of the spiral classifier.

2. Collect the tail water from the spiral classifier in the sand making locomotive workshop and the screening workshop into the water tank of the sand making machine for precipitation, and use the sand making machine to recover the sieving and part of the stone powder and the lost stone from the tail of the spiral classifier in the sand making workshop. For fine sand, the stone powder and fine sand recovered from the sand making machine are sent to the finished sand silo to increase the powder content of the artificial sand and adjust the fineness of the artificial sand.

The raw material of the artificial sand produced by the sand making machine is coarse aggregate with a size of 5-20mm. After the coarse aggregate with a size of 5-20mm is washed twice through the pre-screening and screening workshop, the mud content of the raw material source tends to be zero. The mud is washed and dewatered by the spiral classifier in the sand making machine workshop and the screening workshop, and the mud content of the artificial sand can meet the quality requirements specified in the specification.
