When the steel pipe outer wall shot blasting machine is working, after the preparation work (dust removal system, separator, elevator, horizontal screw conveyor, vertical screw conveyor, roller conveyor, shot blasting machine, etc.) is completed, the machine starts working normally. Firstly, place the workpiece on the roller conveyor outside the chamber and transport it into the shot blasting cleaning room through the roller conveyor. At this time, open the shot blasting gate to start shot blasting cleaning of the workpiece. After cleaning, close the shot blasting gate and transport the workpiece out of the chamber through the roller conveyor.

Shot blasting treatment is carried out through two fixed shot blasting machines at the top, and the steel pipe is transported in a spiral manner. With the rotation of the steel pipe, the surroundings of the steel pipe are cleaned in all directions, leaving no dead corners. The traveling speed of the steel pipe is adjustable, thus achieving control over the shot blasting effect on the surface of the steel pipe. The steel pipe outer wall shot blasting machine for this shipment is mainly customized according to the customer''s conventional steel pipe size. In order to effectively save equipment costs, the shot blasting machine is fixed to clean single specification steel pipes. Customization can also be made according to customer requirements

The steel pipe outer wall shot blasting cleaning machine uses a roller mechanism. When the steel pipe enters the main shot blasting chamber, the shot blasting machine starts working in sequence. After shot blasting treatment, most of the oxide scale, dirt, and other attachments on the surface of the steel pipe are cleaned up, and the surface of the workpiece can reach Sa2-2.5 level. The working mode of the assembly line is continuous circulation. The shot blasting pellets of the shot blasting system are collected and processed by the circulation processing system, and continue to be used by the shot blasting machine and shot blasting system. The working mode of the circulation system is as follows: scattered pellets are transported to the bucket elevator through the lower longitudinal screw conveyor, lower belt conveyor mechanism, and transverse screw conveyor. The bucket elevator lifts the pellets and debris to the upper part of the cleaning room
