All screw conveyor equipment has a hidden danger when transporting powdered materials, which is to prevent dust explosion. The screw conveyor also has such hidden dangers that the dusty flying of the powdery material during the transportation process is normal, and the air diffuses and floats to form a dust cloud. In addition to the air inside the equipment, once the source of the fire is encountered, the possibility of an explosion is not without.

In order to guard against the emergence of such an environment, the manufacturing precision of the equipment deployment is required to be high, and it is necessary to prevent the occurrence of sparks in the friction of parts. Due to the huge cause of the dust explosion and the changing conditions of the production process, the corresponding protection steps are accepted for the poor environment.

The sealing technology has high requirements on the strength of the equipment, and the equipment has a large explosion pressure that can withstand dust without deformation. In the screw conveyor, the upper and lower covers are welded by thick steel plates, which effectively form a closed space. If the explosion-proof measures are adopted on the connecting pipes between the equipment, the production process can be interrupted and the fire can be extinguished in time. For example, an explosion-proof device is placed on the conveying pipe of the material, which effectively functions as an explosion-proof.

Regardless of the material conveyed by the conveying equipment, the use regulations of the conveying equipment should be followed, and the prohibited items must not be done. In order to extend the service life of equipment deployment, maintenance and repair should be held regularly.
