Sand blasting machine is a kind of equipment that uses compressed air as power to spray abrasive onto the surface of workpiece at high speed through sand blasting gun to achieve the purpose of cleaning, descaling, removing oxidized skin, polishing, and strengthening, etc. It is widely used in machinery manufacturing, shipbuilding, automobile, aircraft, bridge, construction, glass, stone and other industries. It is widely used in machinery manufacturing, ships, automobiles, airplanes, bridges, construction, glass, stone and other industries.
The working principle of sand blasting machine is roughly as follows:
Abrasive supply system: Abrasive is usually supplied from the abrasive container (abrasive tank) and enters into the sand blasting machine by gravity or vibration, etc.
Compressed air system: Compressed air is the power source of the sandblasting machine, which is transported to the sandblasting gun through the pipeline.
Blasting gun: The blasting gun is the key component of the sand blasting machine. The compressed air is mixed with the abrasive in the blasting gun and sprayed onto the surface of the workpiece at high speed.
Recycling system: The abrasive and impurities after blasting need to be recycled to recycle the abrasive and reduce environmental pollution.
Safety precautions need to be taken during the sandblasting process, as the high speed abrasive particles may cause personal injury and equipment damage. Operators need to wear professional protective clothing, helmets and goggles and other personal protective equipment.
The following factors should be considered when selecting and using a sand blasting machine:
Workpiece material: different materials may require different types of abrasives and blasting processes.
Size and shape of the workpiece: this determines the size and type of sandblasting machine.
Surface treatment requirements: different treatment purposes such as polishing, rust removal, oxide removal, etc. require different sandblasting processes.
Sand blasting machine plays an important role in improving the surface quality of the workpiece and enhancing the adhesion of the coating layer, which is one of the indispensable equipments in modern industrial production.
