The roller conveyor shot blasting machine is an efficient continuous cleaning equipment for steel surface treatment. It is mainly suitable for surface rust removal, descaling and surface strengthening treatment of large workpieces such as steel plates, steel sections, H-shaped steels, steel structures, and pipes. The equipment transports the workpiece through the roller system, and uses multiple high-efficiency shot blasting machines in a closed shot blasting chamber to perform high-speed projectile impact treatment on the workpiece surface to achieve the purpose of pretreatment or final cleaning.

◆ Application Industry
◆ FAQ
What workpieces are suitable for through-type shot blasting machines?
Through-type shot blasting machines are suitable for continuous surface cleaning and rust removal of large quantities of steel plates, steel sections, welded structural parts, castings and forgings, and are widely used in industries such as ships, steel structures, and machinery manufacturing to improve the surface quality before painting.
What is the working principle of a through-type shot blasting machine?
The equipment delivers the workpiece into the shot blasting chamber through a conveyor roller or mesh belt. Multiple shot blasters throw projectiles at high speed to impact the surface of the workpiece, remove rust, oxide scale or sand, and achieve surface strengthening, thereby improving the durability and adhesion of the workpiece.
How to control dust and noise during the through-type shot blasting process?
The through-type shot blasting machine is equipped with an efficient dust removal system to effectively absorb the dust generated during the cleaning process to ensure that the workshop meets environmental protection standards; at the same time, it uses sound insulation panels and sealing structures to reduce noise pollution and improve the working environment.
