Home / Airless Shot Blasting Machine / Hanger Type Airless Shot Blasting Machine
Closed loop conveyor hanger machine designed for uninterrupted cleaning of suspended components with uniform blasting coverage. Automated movement, reduced manual handling, and efficient abrasive recovery ensure high-productivity surface preparation performance.
The closed-loop conveyor shot blasting machine is built for continuous, high-volume cleaning of medium to large parts that cannot be tumbled. Instead of loading one batch at a time, it carries components on hooks around a continuous overhead loop, so parts move through the blast chamber in an unbroken flow. Loading, blasting, and unloading all happen along the loop without stopping the line.
As a hanger-type airless shot blasting machine, it exposes suspended parts to high-velocity media from several blast wheel units while the hooks rotate for full coverage. Because the loop keeps moving, output stays high and manual handling stays low, which makes it well suited to mass-production plants that need cleaning to run in step with the rest of the line.
Available Configurations
Smart Process Overview
Components are hung on hooks fixed to a continuous closed-loop conveyor. The loop carries them into the blast chamber without pausing, so parts enter, get cleaned, and exit in a steady, unbroken cycle. Each hook rotates as it travels, so steel shot or steel grit from the blast wheel units reaches every face.
Because the conveyor runs as a loop, loading and unloading happen at a station outside the chamber while blasting continues inside. This is what lets the machine run continuously rather than in stop-start batches.
Spent abrasive falls to the hopper and passes through the screw conveyor, bucket elevator, and air wash separator for reuse. The dust collector removes dust and fines, and cleaned parts move on automatically to the next stage.

Custom Engineered Mechanism
The Continuous Closed Loop Type uses a fully automatic conveyor to move components through the blast chamber in an unbroken production cycle. It is built for uninterrupted processing, low manual handling, and a consistent finish across high-volume runs.
This configuration links easily into painting and coating lines, so material flows from cleaning straight into the next stage. Its steady conveyor movement and repeatable finish make it a strong fit for modern, high-output manufacturing plants.
The closed-loop conveyor machine is the right choice when parts cannot be tumbled, and production needs to run without stopping. It gives a uniform, damage-free finish on heavy and delicate fabricated parts while keeping the line moving.
Its modular design supports future expansion and integrates with downstream processes, delivering proven, continuous performance in heavy industries with high daily output.
Closed loop blasting fits industries that run parts in a steady, high-volume flow and want cleaning built into the line. Heavy machinery makers, fabrication units, automotive plants, and railway workshops use it to clean components continuously before coating. The industries below are where a continuous hanger line adds the most value.
