Blasting principle
Shot blasting process uses a transverse principle applies to straight wide strip, throwing the first use of variable frequency motor drive, stepless adjustment of speed pellets projectile speed by throwing the first.
Shot mode you can adjust the orientation applies to two different sets of strip width. Therefore, the best pellets intensity distribution and use of blasting stream can be guaranteed.

Pellets circulatory system
In the blasting chamber by shot blasting pellets into steel projectile motion, a mixture of pellets and scale at the bottom of the blasting chamber collected and transported through the screw conveyor bucket elevator. Minimum diameter pellets bucket elevator vertical transport of the pellets mixture up to the upper screw conveyor, screw conveyor and transported to the pellets separator in the separator, pellets from impurities and small pieces of material (less than requested ) separated and fed into a hopper, feed pellets quantity supplied to the valve for adjusting the throwing head.

3XQ6916X The shot blasting machine, together with auxiliary equipment is stainless steel with a straight-through manner annealing, cooling, after breaking scale, the mechanical descaling and pickling device design. The shot blasting machine is designed in accordance with the requirements of product mix. In actual speed through strip steel, oxide type, strip width, annealing capacity may be. According to ISO8501-1: 1988 standard, the quality of the strip surface reaches Sa2.5 after blasting.
