The difference between shot blasting machine and sandblasting machine

Sandblasting machine and shot blasting machine are two different surface rust removal and surface roughening equipment. The difference between the two:

1.    Sand blasting uses compressed air as the power, and the compressed air carries sand (emery, corundum, etc.) to impact the surface of the workpiece; shot blasting uses an electric high-speed impeller to project steel shots to impact the surface of the workpiece; 2. Different materials are selected for the surface of the impact workpiece. High hardness and wear-resistant materials such as corundum and emery are used for sandblasting, and various special materials and shaped metal particles (called shot blasting) are used for shot blasting;

3.The surface hardness obtained by sand blasting and shot blasting is different, and shot blasting has a surface hardening effect.

Shot blasting machine as a kind of strengthening machine has been widely used around the world. Shot blasting machine uses high-speed rotating impeller to produce high-speed projectile shot blasting machine steel shot to hit the surface of the part to reach the surface of the part for rust removal, cleaning and strengthening. Shot blasting machine is generally used. It is used for rust removal, cleaning, rust removal, and oxide scale removal on castings, forgings, aluminum alloy parts, and hardware workpieces.

Shot blasting machines are divided into :crawler shot blasting machine, hook shot blasting machine, trolley shot blasting machine.There are more than 100 kinds of equipment such as road shot blasting machine and roller type shot blasting machine.

The shot blasting machine is a method of using compressed air to throw the quartz sand at a high speed to clean the surface of the workpiece. Generally, the sandblasting machine is often useful for coating right or wrong, and its technology is used for manual rust removal , Low power, poor site environment and other shortcomings. So now most companies with large output choose shot blasting machines.
