Specifications and models of steel shot for shot blasting machine 

　　Specifications and models of steel shot for shot blasting machine Specifications and models of steel shot for shot blasting machine, curved (surface) blades, can be divided into front curved blades (blades that bend forward in the direction of rotation) and rear curved blades (blades that bend backward in the direction of rotation); according to the data, tubular blades are born to adapt to high-hardness non-metallic abrasives.

　　The material selected for tubular blades is ceramic. It is characterized by wear resistance and can be used continuously at a certain angle after wear, so its service life is longer than that of straight blades. However, since the blade appeared in the early 1970s, due to its complex structure, and once worn, due to the different wear amounts of each blade, the rotation of the shot blasting wheel is unbalanced, and the vibration of the shot blasting machine is aggravated. It is difficult to say whether this shot blasting machine is suitable for large shot blasting machines that eject metal projectiles.

　　Under the conditions of the same diameter and the same speed, straight blades. The absolute speeds of the front curved blades and the rear curved blades are different. The speed of the front curved blade is the highest, followed by the straight blade, and the speed of the rear curved blade is the lowest. Since the pressure and friction exerted by the projectile on the blades are different, a simple analysis shows that the front curved blades are subject to greater pressure and friction, followed by the straight blades, and the rear curved blades are the smallest. Therefore, it is believed that the front curved blades have the shortest life, the straight blades have a longer life, and the rear curved blades have the longest life.

　　In summary, tubular blades have not yet been widely used at home and abroad. The most widely used are pre-bent blades, rear-bent blades and straight blades. Among them, the front curved blades are subjected to the greatest force and wear, but their ejection speed is the highest and the ejection efficiency is the best. The rear curved blades are subjected to less force, more uniform force, and the longest service life, but the ejection speed is the lowest and the ejection effect is the worst. Straight blades are relatively uniform. Therefore, three types of blades are selected according to different situations and different requirements.
