The size of the shot blast wheel has a significant impact on production efficiency, which is mainly reflected in the following aspects:
The number and power of shot blast wheel: Multiple shot blast wheel with high-power motors can significantly improve processing efficiency. For example, 4-8 shot blast wheel with high-power motors (11-37kW per unit) can significantly improve processing speed.
Shot flow rate: Tens of kilograms of shot (such as φ0.8-1.2mm steel sand) can be ejected per minute, with a coverage rate of more than 98%. The size of the shot flow rate directly affects the efficiency and uniformity of shot blasting.
Shot blasting speed: The shot blasting speed refers to the speed of the ejected shot blasting projectiles, which directly affects the effect of surface treatment. The appropriate shot blasting speed should be adjusted according to the material and processing requirements of the workpiece. Generally speaking, the shot blasting speed of metal workpieces should be between 60-80 m/s, and the shot blasting speed of non-metallic workpieces should be between 40-60 m/s.
Shot blasting volume: Shot blasting volume refers to the amount of shot blasting projectiles ejected per unit time, which directly affects the processing efficiency of the shot blasting machine. The appropriate shot blasting volume should be adjusted according to the size of the workpiece and the processing requirements. Generally speaking, the shot blasting volume of small workpieces should be between 30-50 kg/min, the shot blasting volume of medium-sized workpieces should be between 50-80 kg/min, and the shot blasting volume of large workpieces should be between 80-120 kg/min.
Projection angle: The projection angle refers to the angle between the ejection direction of the shot blasting projectile and the surface of the workpiece. The appropriate angle (such as 45°-60°) can make the projectile play a better role, thereby improving the processing effect.
