Product description
The pass-through shot blasting machine is a multi-functional steel pretreatment equipment for cleaning small welded structural parts, section steel and other products. The workpiece is driven by the speed-regulated motor to drive the conveying roller table to send the workpiece into the ejection area of the cleaning room. The shot blasting machine ejects a high-speed and dense beam of projectiles, which hits all parts of the product and performs hree-dimensional and all-round cleaning, so that all surfaces of the steel are The rust layer, welding slag, oxide scale and its dirt fall off quickly to obtain a smooth surface with a certain roughness, which improves the adhesion between the paint film and the steel surface, and improves the fatigue strength and corrosion resistance of the steel. Intrinsic quality, extending its service life.
Application
The machine mainly uses the high-speed shot flow thrown by the high-efficiency and powerful shot blasting machine to blast the surface and inner cavity of the rotating workpiece in the chamber to remove other sticky sand, rust layer, welding slag, oxide scale and other debris, so that the to obtain a fine smooth surface. It improves the adhesion between the paint film and the steel surface, improves the fatigue strength and corrosion resistance of the steel, improves the inherent quality of the steel, and prolongs its service life.

FAQ
What is a shot blast machine?
A shot blaster is a machine that controls the flow or stream of fine metal beads as they are forcibly projected against a surface by mechanical acceleration.
What material is used for shot blasting?
Types of metal abrasives used in shot blasting include steel grit, copper shots, and aluminum pellets. Other methods of shot blasting use silica sand, glass beads, synthetic materials like sodium bicarbonate (baking soda), and even agricultural materials like crushed kernels.
Will shot blasting remove rust?
Shot blasting is the process of abrading the surface of a metal workpiece to remove rust, dirt and other solidified contaminants by hurling a high speed stream of tiny pieces of stainless steel that resemble buckshot. It is capable of deburring, shaping and texturing a surface.
What is the difference between sandblasting and shot blasting?
Essentially, the sandblasting process uses compressed air to shoot some form of abrasive media like sand against the product being treated. Shotblasting employs centrifugal force from a mechanical device to propel treatment media upon the product.
