The inner and outer wall shot blasting machine of the steel pipe is a shot blasting machine for cleaning and spraying the steel pipe by shot blasting. The shot blasting machine mainly removes sand, rust, welding slag, scale and debris from the surface and inner cavity of the steel pipe. The surface of the steel pipe is increased in adhesion and the smoothness of the workpiece is increased, the corrosion resistance and fatigue resistance of the steel pipe are increased, and the service life of the steel pipe is prolonged.

The working order of the shot blasting machine is:

Feeding bracket→feeding system for loading→entry into shot blasting chamber→shot blasting→storing projectile→controlling flow→casting shot workpiece→vertical lifting of bucket elevator→separation of pellets→recycling→sending and throwing Pill room→Unloading system cutting→Unloading bracket. Because the shot blasting machine uses curved blades, the inflow performance of the projectile is improved, so that the throwing power will increase, so that the projecting angle is covered in all aspects, and the maintenance is more convenient.

Steel pipe inner and outer wall shot blasting machine has those advantages:

• The centrifugal force cantilever type multi-functional shot blasting machine has the characteristics of large shot blasting, high efficiency of shot blasting, simple and rapid blade replacement, and the like, and the maintenance is simpler and more convenient.

• The workpiece passes through the inlet and outlet of the shot blasting machine. If it is necessary to clean the special pipe diameter, the infrared carbon and sulfur analyzer will prevent the projectile from flying out, and adopt a multi-layer replaceable sealing brush to achieve complete sealing of the projectile. Do not leak.

• The shot blasting machine adopts the full curtain type BE type slag separator, which can greatly improve the separation amount and separation efficiency and reduce the wear on the blasting machine.
