The shot blasting machine realizes automatic control of the whole machine by means of PLC electrical control, pneumatic valve cylinder pneumatic control loading and unloading system, projectile controllable gate and projectile conveying fault detection. It is suitable for continuous shot blasting of its outer surface before welding or painting, thoroughly removing rust, oxide scale and other dirt, and is an expert in pipeline cleaning. After shot blasting, it can obtain a smooth surface with a certain roughness, increase spray adhesion, improve surface quality and anti-corrosion effect. Its excellent cleaning performance makes the labor-intensive methods of sandblasting and wire brushing obsolete. At the same time, the production cost can be reduced and the output can be greatly improved.
 

The shot blasting machine adopts a filter cartridge dust collector, a one-piece centrifugal polishing head can eject the abrasive in a controllable way and direction, and the shot is circulated. The size of the sealing ring can be adjusted to fit pipes of different diameters, and the replacement is easy. Different from other surface cleaning and pretreatment methods, the shot blasting process without chemical reaction process will not pollute the environment. The shot blasting machine is simple to install, low in cost, and small in space, without pits or other discharge pipelines.
