Pass-through shot blasting machines are engineered as the optimal solution for processing steel plates, sheet metal, structural sections (H‑beam, I‑beam, C‑beam), steel pipes, steel frames, and deformed bars. An integrated brushing and blowing system thoroughly removes all residual abrasives, ensuring a spotless workpiece surface.
In addition to standard models, we also offer custom non‑standard units tailored precisely to your workpiece specifications.

Efficient Cleaning:Rapidly removes oxide layers, rust, and surface contaminants, significantly boosting productivity.
Uniform Finish:Consistent blasting action ensures even surface treatment across the workpiece for reliable, repeatable results.
High Automation:Equipped with automated control systems to enable continuous production and lower labor costs.

We specialize in designing and manufacturing custom shot blasting machines. Each solution is tailored to your workpiece size, weight, and required throughput, delivering optimal performance for your industrial application.

Roller Conveyor System
Consists of infeed, intermediate, and outfeed rollers, forming a continuous, smooth transport line for efficient material handling.

Comprises a preheating chamber, main blasting chamber, and two auxiliary blasting chambers.
Preheating Chamber:Removes surface moisture and metal salts to prepare workpieces for optimal blasting results.
Auxiliary Blasting Chambers:Fitted with four‑layer rubber curtains to prevent shot leakage, protect the environment, and reduce abrasive waste.
Main Blasting Chamber:Strategically angled blast wheels ensure full coverage; manganese alloy liners enhance durability under heavy‑duty operation.

Longitudinal Screw Conveyor:Located at the chamber base, efficiently collects used shot and grit.
Horizontal Screw Conveyor:Transports abrasives to the bucket elevator for seamless recycling.
Bucket Elevator:Lifts used abrasives vertically to the top separator.
Separator:Filters and classifies abrasives, returning qualified shot to the hopper for reuse, minimizing waste.

High-efficiency filtration achieves 99.9% dust removal, creating a clean workplace and safeguarding operator health.

Sweeping:Nylon brushes gather surface shot into the screw conveyor.
Conveying:Screw conveyor transports shot to the bucket elevator.
Blowing:High-pressure fan removes remaining shot from workpiece surfaces.
Lifting Device:Adjusts brush height via a speed reducer for versatile operation.
