The steel plate shot blasting machine is a multi-functional steel pretreatment line for cleaning welded structural parts, H steel, steel sections, grids, and steel plates. It handles the rust removal and polishing of steel plates!

The configuration of the blasting machine is multi-angle, and the world's advanced direct-coupled high-efficient blast wheel is selected to cast a high-speed dense abrasive beam and strike the various parts of the steel in the original state to perform a three-dimensional and all-round cleaning. The rust layer, welding slag, oxide scale, and dirt on each surface of the steel material rapidly fall off, obtaining a smooth surface with a certain roughness, improving the adhesion of the paint film to the steel surface, and improving the fatigue strength and corrosion resistance of the steel material. Improve the inherent quality of steel and extend its service life.

The main functional parts of the machine are the cleaning room, indoor conveyor roller conveyor, and in/out conveyor roller conveyor, shot blaster, abrasive recycling system (including hoisting machine, separator, vertical and horizontal screw conveyor, and abrasive recovery mechanism and pellet feeding pipeline). Body, dust removal, electrical control and other components.

This machine is a high-performance shot blasting equipment for roller conveyor type continuous feeding. During the cleaning process, the steel body or steel is fed into the ejection area of the cleaning machine room by the electrically controlled speed-adjustable conveyor roller. The impact and friction caused by strong dense abrasives from different coordinate positions, the oxide scale, rust layer and its dirt on it quickly fall off, and the surface of the steel material has a smooth surface with a certain degree of roughness. Workpieces. The abrasives and rust dust falling on the steel are purged by the purging device. The splattered mixture is transported by the recovery screw to the chamber funnel, the vertical and horizontal screw conveyor to the lower part of the hoist, and then lifted to the upper part of the machine. In the apparatus, the separated clean pellets are dropped into the separator hopper for shot blasting. Dust generated during shot blasting is sent to the dedusting system through a draft tube. The cleaned gas is discharged into the atmosphere and the particulate dust is captured and collected.

Steel pretreatment equipment is used for the pretreatment of various types of plates and profiles, thus playing a role in improving the quality and added value of steel products produced by steel plants. In the construction of marine engineering projects such as ships and drilling rigs, there is a high demand for the size of the steel. This poses a considerable challenge for various surface treatments because there are a large number of steel plates and special profiles needed during the process. High-quality and efficient pre-cleaning, cutting, welding, painting, and other pre-treatment activities before assembly. The surface treatment as a program is completed on the pretreatment line. The pretreatment line is a process that combines shot blasting, primering, and drying. After this process, the steel plates and profiles are thoroughly blast cleaned, and at the same time, a temporary anti-corrosion coating can be applied. Of course, in addition to the external conveyor equipment, the pretreatment line also includes a preheating furnace, a continuous pass shot blasting machine, a spray booth and a mobile grate with a drying tunnel. On the steel, the equipment is provided with a cross-over conveying system in the area of the cutting material, which allows the material to be uninterruptedly loaded and unloaded and effectively avoids collision damage of the material.
