Sand mill impeller related knowledge

At this stage, with the increasing amount of sand used for engineering, the mechanism sand industry has gradually emerged, and it has driven the entire engineering machinery industry to research and improve the technology and process flow of heavy mineral processing equipment. As the sand making machine, an important part of the sand production line, the stability and durability of its components are very important. Today, Shanghai GM has provided relevant knowledge about the sand making machine impeller.

The impeller is an important part of the sand making machine, and it is also a fragile part. The materials are delivered and distributed in the impeller. If the operation is improper, it is easy to cause the material to wear the impeller. Therefore, we should be extra careful in the specific work and operation. In case of carelessness or carelessness, a series of production accidents will occur.

We know that the impeller is mounted on the upper shaft end of the main shaft assembly. The torque is transmitted by means of a conical sleeve and a key coupling, and the rotation is performed at a high speed. The material enters the center of the impeller from the central feed pipe of the part feeder on the impeller. The vertebral body at the center of the impeller distributes the material evenly to the respective emission channels of the impeller. At the outlet of the emission channel, wear-resistant blocks made of special materials are installed and can be replaced. The impeller accelerates the material to a certain speed and throws it out. It impacts the material lining inside the turbulent crushing chamber and performs strong self-crushing. The upper and lower runner plates are installed between the cone cap and the wear block of the impeller to protect it. Not subject to wear and tear.

When the equipment is stopped, it should be noted that: before stopping the discharge equipment, it is necessary to stop the feeding first, and the feeding materials should also continue to be uniform. The specifications of the materials strictly comply with the requirements, or else the impeller is easily worn out due to the material.

The industry believes that the impeller device, which plays a decisive role in material ejection by the sand making machine, is an important component. The stability of its operation determines the working efficiency of the associated conveyors, feeders, and sorters. Shanghai GM reminds users of the sand making machine to pay attention to improving the stability of the impeller device, not only improving the production efficiency of the sand making production line, but also prolonging the service life of the sand making machine.
