Steel shot and steel sand are recommended to be used together

　　The shape of the steel ball is relatively regular, almost spherical shape, smooth surface. Steel sand is irregular shape of sand, is broken into steel pellets, its surface has concave and convex corners.

　　From the shape of the two can basically judge the effect of cleaning the workpiece, the surface of the steel shot cleaning is smooth, and the surface of the steel sand cleaning is rough. Steel shot and steel sand can be used for surface rust removal, but if the need for surface strengthening, it must have the role of steel shot, steel sand also has his advantage, that is, the cleaning of the workpiece is relatively clean without dead Angle.

　　The best combination to clean the casting is to match the steel shot and steel sand, so that the steel sand can be thrown to the corners, and other parts of the steel shot can be thrown, which will also avoid the casting surface is not smooth

　　The choice of steel shot should be moderate in hardness and size. You can consult us according to the type of workpiece cleaned. The right combination of steel shot and steel sand can reach every place in the cleaning room and reduce the processing time. The hardness of the steel shot and steel sand is proportional to the cleaning speed, but inversely proportional to the life, if the surface roughness of the material being cleaned. The higher the roughness, the greater the consumption of steel shot or steel sand.
