What is impeller type?

Wheel blasting uses a motor to drive the impeller body to rotate, and uses centrifugal force to throw cast steel shot/grit (alloy shot, steel cut wire, stainless steel shot, etc.) with a diameter of 0.2 to 3.0mm, hit on the surface of the work. So that the surface of the workpiece reaches a certain degree of roughness, improve the adhesion of painting, or changes the welding tensile stress of the work to compressive stress, and improves the service life of the work. It is almost used in most fields of machinery, repairing ships , Auto parts, aircraft parts, gun and tank surfaces, bridges, steel structures, glass, steel plates, pipes, etc.

What is air nozzle type?

Sandblasting is a method of using compressed air to blow out the sand at high speed to clean the surface of the part. Which not only removes rust, but also removes oil incidentally, it is very useful for painting.
