The Gostol VK shot blasting machine with overhead conveyor cleans parts of various shapes and sizes in a continuous process, making it suitable for companies with small and medium production volumes.

Overhead conveyorWorkpieces are hung on conveyor hooks that move through the shot blasting chamber.
Comprehensive cleaningThe shot blasting wheels' flow cleans all sides of the parts, as the parts rotate slowly during movement.
Continuous processThe process operates in continuous circulation — new parts are loaded while clean ones are unloaded simultaneously.
Wear-resistant housingThe machine housing is protected by wear-resistant manganese steel liners.

The overhead conveyor shot blasting machine is designed for cleaning workpieces of various shapes, sizes, and weights that are suspended on hooks or hanging elements attached to the conveyor.

How it works

The workpieces are hung on conveyor hooks that move through the blasting chamber. The flow of the blast wheels cleans all sides of the parts, as the parts rotate slowly during movement. The process runs in continuous circulation — new parts are loaded at the same time as clean ones are unloaded.

Durability and suitability

The machine body is protected by wear-resistant manganese steel liners. The overhead conveyor shot blasting machine is well suited for companies with small to medium production volumes, where the parts to be blasted vary in shape and size.

Lining materialWear-resistant manganese steel
FlexibleSuitable for cleaning workpieces of various shapes, sizes and weights.
Continuous workflowSimultaneous loading and unloading keeps the process uninterrupted.
Complete cleaningRotating the parts ensures uniform cleaning of all sides.
Long-lastingWear-resistant liners protect the machine housing and extend its service life.
IR shot blast wheel — higher impact energyAccording to the manufacturer's data, Gostol's proprietary IR blast wheel delivers up to 70% greater impact energy and, with curved blades, a 27–30% higher abrasive discharge velocity — a shorter cycle and higher productivity.
Lower energy and abrasive consumptionAccording to the manufacturer, the optimised internal geometry and contactless seal reduce energy consumption by up to 10–25% and abrasive consumption by up to 25% compared to a classic blast wheel.
Carbide wear parts and quick-changeWear parts ranging from cast iron and tool steel to hard metal (widia), over 150 combinations; quick replacement of wear parts in ~15 minutes keeps downtime to a minimum.
