Description

Technical Field

[0002] The shot blasting machine uses a high-speed rotating impeller to throw the projectiles onto the workpieces that are continuously turning over in the drum, so as to achieve the purpose of cleaning the workpieces. It is suitable for sand removal, rust removal, oxide skin removal and surface strengthening of castings and forgings weighing less than 15 kg in various industries. The shot blasting machine relies on a high-speed rotating blasting head to throw abrasive particles onto the surface of the workpiece. There are several blades inside the blasting head. When working, the abrasive enters the center of the blasting head through the feed port. In the center of the blasting head, there is a shot dividing wheel that rotates with the blasting head, and the outside of the shot dividing wheel is a directional sleeve.
