What is the principle and use of dry sandblasting machine?

Dry sandblasting machine is a common surface treatment equipment. Its principle is to use high-speed sand particles to impact the surface of the workpiece to remove the dirt, oxide layer and coating on the surface, so as to achieve the purpose of cleaning, adjusting roughness and increasing adhesion.

Dry sandblasting machine is mainly composed of compressed air system, sandblasting gun, sand supply system and waste collection system. When working, sand is sent into the sand blasting gun by compressed air, and then sprayed out through the nozzle to form a high-speed jet of sand particles, which impacts the surface of the workpiece, thus achieving the effect of surface treatment.

Dry sandblasting machine is widely used. First of all, it can be used to clean and remove dirt, oxide layer, corrosion and so on on the surface of the workpiece, so that the surface of the workpiece can be smooth again. Secondly, it can be used to adjust the surface roughness. By controlling the pressure of sandblasting and the type of sand, different roughness requirements can be achieved. In addition, dry sandblasting machine can also be used to increase the adhesion of workpiece surface, which provides a good foundation for subsequent painting and spraying processes.

Generally speaking, dry sandblasting machine is an efficient, flexible and reliable surface treatment equipment, which is widely used in automobile manufacturing, shipbuilding, machinery manufacturing, architectural decoration and other industries, and provides an effective solution for workpiece surface treatment.
