Shot blasting machine is a widely used mechanical equipment in the fields of metal processing, casting, automobile manufacturing, etc. It uses the high-speed rotating blast wheel to spray steel shots or other granular materials onto the metal surface, to remove dirt, oxide scale, rust, and other impurities, making the surface smooth, flat, and enhancing the surface roughness and adhesion.
Shot Blasting Machine Working Principle
Shot Blasting Process
The core of shot blasting machine working principle lies in the shot blasting process. The motor drives the blast wheel to rotate at high speed, generating strong centrifugal and wind forces. When steel shots or other granular materials are fed into the blast wheel, they are accelerated under the action of centrifugal force and thrown onto the metal surface to be treated. The high-speed impact and friction of the steel shots effectively strip impurities from the metal surface while achieving a certain roughness in the surface, providing a good foundation for subsequent coating treatment.
Material Circulation System
The shot blasting machine is also equipped with a complete material circulation system. The steel shots and removed impurities are conveyed to the bucket elevator through the spiral conveyor at the bottom of the shot chamber, then lifted to the top by the elevator, and transported to the shot separator by the upper spiral conveyor for separation. The clean steel shots after separation re-enter the shot storage bin for recycling, while the broken shots and impurities are discharged through the waste pipe. This system ensures continuous supply and efficient utilization of shot blasting materials.
Common Types
Steel pipe shot blasting machine is a device specifically used for cleaning the inner and outer walls of steel pipes. The steel pipe shot blasting machine uses the high-speed shots thrown by the shot blaster to impact and clean the surface of the steel pipe, effectively removing oxide scale, rust layers, and other impurities, improving the quality of the steel pipe surface. The steel pipe shot blasting machine is suitable for surface treatment of batch steel pipes before welding or painting, significantly improving the adhesion and anti-corrosion effect of the steel pipe coating. The steel pipe shot blasting machine has advantages such as high production efficiency, high automation level, and good cleaning effect.
Wire rod shot blasting machine is a high-efficiency surface treatment device mainly used to clean or strengthen the surface of various metal wires. The wire rod shot blasting machine sprays steel shots or other abrasives onto the wires through a high-speed rotating blast wheel to remove surface oxide layers, rust, and oil stains, thereby improving the surface quality and adhesion of the wires. The wire rod shot blasting machine has advantages such as compact structure, convenient operation, energy saving and environmental protection, and high safety, and is widely used in industries such as construction, bridges, mining, machinery manufacturing, and automobile manufacturing, playing an important role in improving product quality and market competitiveness.
