How to choose between shot blasting machine and sandblasting machine

　　How to choose between shot blasting machine and sandblasting machine? What is the difference between sandblasting machine and shot blasting machine? Let us first understand how each works.

　　The shot blasting machine uses a motor to drive the shot blasting device, generating strong centrifugal force, and projecting abrasives (copper shots, cut steel wire shots, stainless steel shots, etc.) with a diameter of 200-5000μm on the surface of the object, so that the surface of the object has a certain roughness. The appearance of the object improves the surface stress and adhesion of the object. The practice is to use a high-speed rotating impeller to throw small steel shots or small iron shots out to hit the surface of the parts at high speed, so the oxide layer on the surface of the parts can be removed. Abrasives are thrown by the impeller of the shot blaster, and the viewpoint cannot be changed. The only variables are the rotation speed and the shot blasting amount.

　　The sandblasting machine uses the principle of air compression as a dynamic eruption abrasive. The abrasive used is fine sand (steel sand, emery sand, glass sand, etc.) with a diameter of 5-40μm to spray on the surface of the workpiece to remove surface oxides. According to the material and thickness of the abrasive, the cleaning effect is also different, and the same can achieve the purpose of strengthening the workpiece.

　　Compared with sand blasting machine, the cleaning efficiency of shot blasting machine is higher than that of sand blasting machine. However, the shot blasting machine is fixed and cannot be moved at will. It cannot clean workpieces that are difficult to move. However, the sand blasting machine is more random. , No matter when and where, the workpiece to be cleaned can be cleaned up. Furthermore, the shot blasting machine cannot be closed immediately. Due to the high-speed rotation of the shot blasting machine, the closing time is delayed, and the sand blasting machine can be stopped and opened immediately.

　　In summary, whether it is a sand blasting machine or a shot blasting machine, the cleaning effect that can be achieved is the same, the only difference is the difference in the data and size of the processed workpiece. Therefore, it is necessary for us to make selections based on our own practice when selecting exterior processing equipment.
