Shot blasting machines

Gostol HR-1B – rotary drum shot blasting machine

The Gostol HR-1B rotary drum shot blasting machine effectively cleans smaller castings, forgings, and heat-treated parts thanks to its wear-resistant construction.

Rotary drumWorkpieces are loaded into the drum manually or with the aid of a loader and are discharged by tilting the drum.
Wear-resistant housingThe machine housing is protected by wear-resistant manganese steel liners.
Abrasive Recycling SystemHigh efficiency is ensured by a continuous abrasive material handling and recycling system.
Durable wheelsShot blasting wheels are made from wear-resistant materials.

The rotary drum shot blasting machine is suitable for cleaning smaller cast parts, forgings, heat-treated components and parts from machine repair workshops.

How it works

Workpieces are loaded into the drum manually or by means of a loader. During unloading, the drum is tilted to a certain position and the objects fall into a container. Using a loader, we achieve a partially automated cleaning process.

Durability and efficiency

The machine housing is protected by wear-resistant manganese steel liners. The high efficiency of the drum shot blasting machine is ensured by a continuous abrasive handling and return system and by shot blasting wheels made of wear-resistant materials.

Partial AutomationUsing the loader achieves a partially automated cleaning process.
Long service lifeWear-resistant manganese steel liners extend the machine's service life.
High efficiencyThe continuous abrasive material handling system ensures efficient cleaning.
Flexible loadingWorkpieces can be loaded either manually or using a loader, as required.
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.
