1) Application scope
Steel is mainly used for surface cleaning and removal of scale, rust and foreign matters, welding H steel, section steel, steel plate and metal components, removing oxide scale, rust and foreign matters on the surface, and thus obtaining a pure metal surface. Shot blasting machine accessories Casting equipment for cleaning or strengthening the surface of castings by high-speed projectiles thrown by shot blasters. The shot blasting machine can sand, core and clean the casting at the same time. Some areas are also known as sanding machine, sand blasting machine. The wearable parts of shot blasting machine are different from shot peening machine in that they are used to reduce the fatigue life of parts, increase different surface stresses, increase the strength of parts, or prevent fretting. Vulnerable parts of shot blasting machine It is a kind of treatment technology that the steel sand and steel shot are thrown and impacted on the surface of material objects at high speed by shot blasting device. Compared with other surface treatment technologies, it is faster and more effective, and can be used for the casting process after partial retention or stamping. Shot blasting machine can solve a problem of shooting, specific varieties of sand blasting machine cleaning machine, saving production costs, greatly improving production efficiency. The multi-function shot blasting machine can be used to optimize the production process of welding steel, steel and other steel surface state, improve the corrosion resistance, increase the coating tightness, and improve the appearance quality and internal quality of products, greatly reducing the labor work of cleaning intensity and environmental pollution.

Structure and working principle description of blasting materials:
1. Working principle:
The blast cleaning equipment used in this project is roller conveyor type high-performance shot blasting cleaning and equipment. In the cleaning process, the speed control motor can drive the social transport roller table to send the workpiece into the blasting area in the cleaning room, and all sides of the workpiece are affected by the impact and friction of dense powerful projectiles from six shot blaster assemblies with different development directions in China Due to the intensive surface deformation of the workpiece and the workpiece, there is a certain degree of surface deformation due to the surface roughness of the workpiece.
During the cleaning process, the pellets are scattered to the main body of the dust collection chamber, and the mixture is collected in the screw conveyor, and then the dust particles are transported to the separator through the lower shell hoist elevator and the belt conveyor. When the dust particles are dropped through the separator, the dust removed by the air is blown, and the pellets are thrown out by the blower wheel delivery system.
The air dust from a separator and cleaning workshop can be driven by a fan. Through different air duct pipeline management systems, bag filter dedusting can achieve a maximum efficiency of 99. After purification, the air is discharged into China's atmosphere through the chimney, and the particulate dust is captured and collected.
