Sandblasting machine is a device that uses compressed air as power to spray abrasive at high speed onto the surface of the workpiece through a sandblasting gun, in order to achieve cleaning, rust removal, oxide scale removal, Polishing, strengthening and other purposes. It is widely used in industries such as mechanical manufacturing, ships, automobiles, airplanes, bridges, construction, glass, and stone.

The Working Principle of sandblasting machine is roughly as follows:

Abrasive supply system: Abrasive is usually supplied by abrasive containers (abrasive cans) and enters the sandblasting machine through gravity or vibration.

Compressed air system: Compressed air is the power source of the sandblasting machine, which is transported to the sandblasting gun through pipelines.

Sandblasting gun: Sandblasting gun is a key component of sandblasting machine. Compressed air is mixed with abrasive in the sandblasting gun and sprayed onto the surface of the workpiece at high speed.

Recycling system: The sprayed abrasive and impurities need to be recycled to recycle the abrasive and reduce environmental pollution.

Attention should be paid to safety protection during sandblasting, as high-speed abrasive particles may cause personal injury and equipment damage. Operators are required to wear professional protective clothing, helmets, goggles, and other personal protective equipment.

When selecting and using a sandblasting machine, the following factors should be considered:

Workpiece material: Different materials may require different types of abrasives and sandblasting processes.

The size and shape of the workpiece determine the size and type of sandblasting machine.

Surface treatment requirements: Different treatment purposes such as polishing, rust removal, and oxide scale removal require different requirements for sandblasting processes.

Sandblasting machines play an important role in improving the surface quality of workpieces and enhancing the adhesion of coating layers, and are one of the indispensable equipment in modern industrial production.
