Pipe outer wall shot blasting machine

including roller conveyor shot blasting machine and diabolo shot blasting machine.

Roller conveyor shot blasting machine

Roller conveyor shot blasting machine suitable for blasting of small diameter steel pipes, multiple pieces can be blasted at one time.

Suitable for shot blasting of small diameter steel pipes, multiple pieces can be cleaned at one time.

In the blasting process, use the roller conveyor system which is controlled by frequency converter to transmit steel pipes into the blast chamber, blast wheel throw steel shot and hit the surface of steel pipes, make oxide layer and dirt rust wore off quickly, after the pipes blasting, sent out from the other side.

Diabolo shot blasting machine

Diabolo shot blasting machine suitable for blasting big diameter steel pipes, usually one time blast one pipe. But one machine can blast different diameter pipe.

steel pipe moves through the machine on skew roller conveyors. Such form of the conveyor provides simultaneous rotation and transition movement of the pipes through the machine, which can achieve evenly blasted surface. Blast turbines made from wear-resistant materials, with power from 5.5 to 45kw provide efficient and quality shot blasting. The shot blasting part of the machine’s robust housing is protected by wear-resistant shields made from manganese steel. Entry and exit seals chamber with a series of rubber screens keep the abrasive inside the machine.
