Steel plate profile pretreatment line shot blasting machine

Steel plate profile pretreatment line shot blasting machine is a kind of equipment specially used for surface cleaning, rust removal and roughness increase of steel plate and profile. It is usually used in the pretreatment process of large-size workpieces such as steel plates and profiles to provide a clean basis for subsequent painting, galvanizing or other surface treatment.

The working principle is as follows:

Feed system: The feed system where the steel plate or profile is fed into the shot blasting machine through the conveyor. The feed system usually includes a roller table or conveyor belt to ensure smooth entry of the workpiece into the shot blasting machine.

Shot blasting chamber: The feed system feeds the workpiece into the shot blasting chamber, which is a confined space. The cleaning room has a high-speed rotating shot blast and spray gun.

Shot blasting cleaning process: Start the shot blasting device and project the shot blasting particles onto the workpiece surface. Shot blasting particles have a certain impact force, which can remove the oxidation layer, rust and other dirt on the surface of the workpiece. At the same time, the spray gun will release cleaning agents (such as water or solvents) to help clean the surface of the piece.

Shot blast particle recovery and reuse: During the cleaning process, shot blast particles bounce back after contact with the workpiece surface and are recovered by the recovery system. After screening and cleaning, the recovered shot blasting particles can be used again to realize the recycling of shot blasting particles.

Discharge system: The cleaned workpiece leaves the shot blasting machine from the shot blasting chamber through the discharge system, usually via the roller table or conveyor belt.

In general, the steel plate profile pretreatment line shot blasting machine uses high-speed rotating shot blasting particles and spray guns to carry out impact cleaning on the surface of steel plates and profiles, while achieving continuous and efficient pretreatment operations by recovering and reusing shot blasting particles. This can provide clean and suitable roughness workpiece for subsequent surface treatment such as coating and galvanizing.
