A sandblasting machine is a kind of equipment that uses compressed air to spray sand onto the surface of the workpiece at high speed to clean or change the shape. Compared with manual sandblasting machine, the sandblasting machine has the advantages of easy operation, high efficiency, energy saving and environmental protection. According to different workpiece shapes and requirements, the sandblasting machine can adopt different structures and methods, such as turntable type, crawler type, conveyor type, through-type type, drum type, open type, etc. The main components of the sandblasting machine are sandblasting chamber, sandblasting gun, recovery system, dust removal system, control system, etc.
The working principle of the sandblasting machine is: firstly, the sand is loaded into the storage bucket or hopper, and then it is fed into the sandblasting gun by compressed air, and it is accelerated by the nozzle to spray out to form a high-speed sand flow. The sand flow impacts the surface of the workpiece at a certain distance and angle, producing peeling and cutting effects, removing dirt, oxide layer, burrs, etc. on the surface of the workpiece, and at the same time producing a certain roughness on the surface of the workpiece. The impacted sand and impurities are collected by the recycling system, filtered and separated, and then the clean sand is re-fed into the storage bucket or hopper for recycling. The dust generated in the recycling system is absorbed and treated by the dust removal system to ensure environmental hygiene. The control system can control the movement and stop of the blasting gun according to the set parameters and procedures, so as to realize the sandblasting process.
The application field of sandblasting machine is very wide, mainly including the following aspects:
Metal surface treatment: The sandblasting machine can clean the surface, remove rust, remove oil, remove the oxide layer and other treatments on various metal materials to improve the adhesion and corrosion resistance of the metal surface. At the same time, the sandblasting machine can also beautify, engrave, pattern and other decorative treatments on the metal surface to increase the aesthetics and value of the metal surface.
