The trolley-type shot blasting machine is designed for cleaning large and heavy workpieces that need to be cleaned individually or in small quantities. The machine is ideally suited for surface treatment of castings, forgings and structures.

How it works

Workpieces are loaded onto the trolley outside the blasting chamber and transported into the chamber. During blasting, the trolley rotates, ensuring uniform cleaning in every position.

Durability and efficiency

The machine housing is protected with wear-resistant manganese steel liners. High efficiency is ensured by blast wheels made of wear-resistant materials and a continuous abrasive handling system.

Uniform cleaningThe rotating carriage ensures uniform cleaning of the workpiece in every position.

Long service lifeWear-resistant manganese steel liners extend the machine's service life.

Suitable for heavy partsThe machine is designed for cleaning large and heavy workpieces individually or in small batches.

High efficiencyWear-resistant blasting wheels and continuous abrasive handling ensure efficient operation.

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.
