Why is the screw conveyor blade damaged?

The main wear parts of the screw conveyor are blades, suspension bearings and screw ends. Then today,I will talk to everyone about why the screw conveyor blades are damaged.

Main cause of damage

Damage factor

In addition to the natural factors such as environment, temperature, material and material, more are the structural factors and human factors of the screw conveyor components. The use of the screw machine is still based on some conditions of use of the screw machine to ensure the degree of damage of the screw machine and the spiral blade. In the use of the screw machine, In the use of screw conveyors, we must carry out some maintenance on the screw conveyor in order to extend the life of the screw conveyor and the blades.

The damaged part

The blade wear of the screw conveyor is mainly distributed at the edge of the blade, and the farther away from the inner edge of the screw conveyor, the more serious the blade wear of the screw conveyor. The damaged part of the screw machine is inseparable from the working principle of the screw machine. The screw conveyor machine mainly uses the blade to push the material during the work, which causes the friction between the material and the screw machine to make the blade suffer a certain degree. Wear and long-term use of the screw conveyor will cause damage to the blade.

The impact of working principle

The wear of the blade of the screw conveyor is different from the normal contact wear. That is, when the screw conveyor conveys the material, the blade extrudes the material, and the force of the blade is equivalent to the variable load of the equal section conveyor acting on the cantilever beam, the farther from the transmission shaft,the greater the force, and the greater the amount of deformation, and the greater the number of cracks that form voids, resulting in greater wear of the blade. Therefore, the outer edge wear is much greater than the inner edge wear. The main reason is that the working principle of the screw conveyor is mainly based on the blade. Therefore, the damage of the blade of screw conveyor will definitely occur, we can only reduce the damage.

According to the above, I believe that the damage of the screw blade should be the work of the screw conveyor. The main thing is that we should pay attention to the maintenance of the screw conveyor parts when using the screw conveyor to reduce the damage of the screw conveyor blades.
