Influencing factors of abrasives mechanical strength, and impellers

What is the specific definition of strength and shot peening in shot blasting machinery?
Strength: In mechanics, the ability of a material to resist damage under external forces, like resistance to deformation or fracture, is called strength. Moreover, this performance is one of the basic requirements that mechanical components must meet and satisfy.

Shot peening: shot peening is a surface strengthening process widely used in shot blasting machines. It has the advantages of simple equipment, convenient operation and no limitation on the shape and position of the workpiece. Its purpose is to improve the mechanical strength of the parts, their wear resistance, corrosion resistance 
and fatigue resistance, as well as to eliminate residual stress in the parts.

Factors affecting the mechanical strength of abrasives are: 
The size of abrasives: Generally, the larger the abrasives, the larger the impact kinetic energy, and the greater the blasting strength, but the coverage of shot blasting will decrease. Therefore, while the shot blasting strength can be ensured, the smaller size shot blasting can be used as much as possible. However, it is necessary to look at the shape of the part to check if it will be restricted. 

Abrasives hardness: If the hardness of the abrasives is higher than that of the part, the hardness value changes so that the shot blasting strength is not affected. On the contrary, if the hardness of abrasives is lower than the hardness of the 
part, when the hardness of abrasives is lowered, the shot blasting strength is lowered.

Shot blasting speed: Increasing the speed of shot blasting will increase the shot blasting strength, but at the same time, it may increase the amount of 
blasting damage. Therefore, we should find a balance between the two so as to have a suitable shot blasting speed and good shot blasting effect.

In the shot blasting machine, are impellers wearing parts?
In the shot blasting machine, the impellers are consumable parts, and they are also important parts. Therefore, it is necessary to pay attention to and take care of impellers to ensure the normal use of the shot blasting machine and the good use effect. In terms of specific maintenance, it is necessary to use them correctly and in a standardized way, and for vane materials, high wear-resistant material should be used, so that the service life of the impellers can be ensured.
