Steel shot and steel grit are recommended to be used together

　　Steel shot has a relatively regular shape, almost spherical shape, and a smooth surface. Steel grit is an irregular-shaped sand-like substance, which is made from broken steel shot. Its surface has uneven and angular shapes.

　　The effect of finishing the workpiece can be basically judged from the appearance of the two. The surface of the workpiece treated with steel shot is smooth, while the surface of the workpiece treated with steel sand is rough. Both steel shot and steel sand can be used to remove rust on the surface, but if the surface needs to be strengthened, it is necessary to have the effect of steel shot. Steel sand also has its advantages, that is, the workpiece is cleaned and there are no dead ends.

　　The best combination for cleaning castings is to use steel shot and steel sand in combination, so that the steel sand can be thrown to the edges and corners, while the steel shot can be thrown to other parts. This will also prevent the surface of the cast casting from being lubricated.

　　The selection of steel shot should have moderate hardness and size. For details, you can consult us according to the type of workpiece to be cleaned. The appropriate combination of steel shot and steel grit can reach every place in the cleaning room and can also reduce the processing time. The hardness of steel shot and steel grit is directly proportional to the cleaning speed, but inversely proportional to the service life, if the surface roughness of the material to be cleaned is rough. The higher the roughness, the greater the consumption of steel shot or steel grit.
