Steel shot and steel grit are recommended to be used together

　　The steel shot is relatively regular in shape, almost spherical in shape, and has a smooth surface. Steel grit is a sand-like object with irregular shape, which is made by crushing steel shot, and its appearance has unevenness and edges and corners.

　　The effect of finishing the workpiece can be basically judged from the appearance of the two. The surface of the workpiece cleaned by steel shot is smooth, while the surface of the workpiece finished by steel grit is rough. Both steel shot and steel grit can be used to remove rust on the surface, but if surface strengthening is required, the effect of steel shot must be used. Steel grit also has its advantages, that is, the cleaned workpiece is relatively clean without dead ends.

　　The best combination for cleaning castings is the matching of steel shot and steel grit, so that the steel grit can be thrown to the corners, while other parts of the steel shot can be thrown, which will also prevent the surface of the cast casting from being lubricated

　　The hardness and size of the selected steel shot should be moderate. You can consult us according to the type of workpiece to be sorted. The appropriate combination of steel shot and steel grit can reach every part of 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 is inversely proportional to the service life, if the surface roughness of the material to be cleaned. The higher the roughness, the greater the consumption of steel shot or steel grit.
