G Series – Manganese Steel Belt Tumble Shot Blasting Machine

Manganese steel belt tumble shot blasters are designed for mass production of ferrous and non-ferrous castingsforgingswelding, and heat-treated parts that can withstand part-on-part friction.

They can be used for shot blasting of castings, forged and pressed parts, and cold or hot formed parts varying in complexity and shapes (ex. springs, etc.) in sizes. Although they are usually used in batch cycles, they can also be integrated in a fully automatic production with the addition of loading/unloading devices.

G Series shot blasters are extremely versatile and adaptable to different types of parts and applications. Tumblers can process a set of small workpieces weighing up to 2,200 lb, or individual parts up to 2,000 l / 10,100 lb.

The G Series is different from the GG Series rubber belt tumble baster as it can hold much larger parts, heavier per piece weight and is a must use machine if the parts are warm or hot coming from an oven or if the parts have sharp edges on them that could damage a rubber belt design.

How it Works

Parts are loaded inside the blasting area in an endless caterpillar with manganese steel flight belt that forms a drum.

The abrasive is propelled by the ir sm@rt multi-option blast wheels ranging from 5.5 to 30 kW located above the belt.

During the blasting cycle, the caterpillar moves, causing the parts to tumble, turn, and rotate over one another (usually at 3-5 RPM) so that their entire surface is evenly and efficiently exposed to the blast stream.

To unload parts from the tumbler, the manganese steel belt rotation is switched in the opposite direction to dump either into a customer provided tote or onto a conveyor belt.

In a fully automated production process, parts are loaded by the means of hydraulic skip loader tailored to the customer’s specifications. When finished, parts are discharged onto a vibratory or belt unload channel conveyor and diverted to the next working station.

Abrasive media reclaiming system

After use, residual abrasive media falls down the bottom of the blasting chamber, where it is conveyed by screw conveyors and a bucket elevator to an automatic media cleaner.

The abrasive reclaimer provides continuous handling and recycling of abrasive media based on particle size in order to maintain optimal and consistent quality blasting.

For heavily regulated applications, a magnetic and/or vibratory particle separator can be added to precisely sort the abrasive shots based on their size and density.

Standard Features

All shot blasters are equipped with PLC, display, timer, automatic or manual mode, automatic start-up of the blast wheels, working-hours counter, and other basic features.

Blast wheels and blasting chamber inner walls are protected by wear-resistant shields made from manganese steel liners for extremely long service life.

Optional Features

Blast wheels can be equipped with a frequency drive and ir sm@rt valve to precisely control the flow of media for optimal results.
