Sandblasting Machine & Air Compressor

An automatic sandblasting machine is a machine that uses compressed air as the power to form a high-speed jet beam and spray the material at high speed to the surface of the workpiece to be processed. So that the mechanical properties of the outer surface of the workpiece surface are changed. Air compressor is the basic product of modern industrialization. It is a device that converts the mechanical energy of the prime mover (in general, electric motor) into air pressure energy.

How to Choose Air Compressor?

The use of a sandblasting machine is inseparable from the air compressor. The air generated by the air compressor acts as a motive force in the sandblasting process. Different sandblasting machines need different air compressors. Sandblasting machines can be divided into general pressure wet sandblasting machines, pressure sandblasting machines, and high pressure sandblasting machines in terms of the efficiency and strength of sandblasting. The air compressor connected with the sandblasting machine generally selects a pressure of 0.8Mpa. Then select the appropriate air compressor according to the size of the air source required by the sandblasting machine.

What types of sandblasting machines?

The normal pressure sandblasting machine is the siphon sandblasting machine. Compared with the other two types of sandblasting machines, the efficiency of sandblasting is lower than that of pressurized and high-pressure sandblasting machines. The air compressor required for each gun on this type of sandblasting machine has an air output of at least 1 cubic meter per minute, that is, an air compressor of at least 7.5KW.

Both pressurized sandblasting machines and high-pressure sandblasting machines belong to pressure-feeding sandblasting machines. The blasting efficiency of a single gun is lower than that of the high-pressure type. The air compressor required for each gun on the pressurized sandblasting machine has an air output of at least 2 cubic meters per minute, which is a 15KW air compressor.

The air compressor required for each gun on the high-pressure sandblasting machine has an air output of at least 3 cubic meters per minute, which is a 22KW air compressor. Click here to know more about grit blasting machine manufacturers.

Optional machine

In general, the bigger the air compressor, the better. If you consider the cost, you can refer to the above data for selection. The air compressor and the sandblasting machine need to be equipped with an air storage tank and a dryer. The gas storage tank is used to store the gas generated by the air compressor to ensure the stability of the air source. The dryer is used to dry the oil and moisture in the air to ensure that the air is dry when it reaches the sandblasting machine. It also reduces sand blocking problems caused by sand agglomeration.
