VKP Series – Overhead conveyor shot blasting machine with hook

Spinner hanger shot blasters are typically designed to process mixed loads of medium and large components varying in complexity and shapes in continuous flow production. It can be used for blast cleaning, desanding, and decoring in die cast industry, as well as for descaling, removing dust, and reconditioning in the metal-working industry.

This process is ideal for delicate and sensitive parts that cannot withstand part-on-part friction in other solutions such as tumblers or rotating drums as well as for heavy and complex-shaped workpieces like castings, welded components, forged and pressed parts, cold or hot formed, and complicated parts such as cylinders, springs, etc.

VK Series shot blasters can easily be integrated in continuous flow production with monorail and hangers moving parts from one station to another.

The hanger can carry parts load of up to 110,000 lb or more. The shape of the hanging conveyor, housing size, load capacity, hook lift and trolley drive, type and course of the hanging rail, and blast wheels number, horsepower and position as well as frequency regulation of blast wheel’s revolutions are based on the process requirements.

How it Works

Parts can be hung individually or in a cluster on revolving hooks and transported to the blasting area on circular closed loop monorail conveyors.

Inside the blasting chamber, parts rotate and are exposed to the abrasive propelled by the ir sm@rt multi-option blast wheels ranging from 5.5 to 30 kW, providing efficient shot blasting and quick results.

During shot blasting, workpieces rotate on revolving hooks, and they move forwards and backwards within the abrasive blast stream, which enables efficient processing of hard-to-reach blind spots.

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.

VKP Series spinner hangers are delivered with a set of revolving hooks and pneumatic cylinders on doors with shutoff valves when doors are open.

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.

The housing can optionally be entirely made of manganese and added with liners to increase its service life even more.

Transport of workpieces can be performed by Morris chain, Power & Free conveyor or conveyor with trolleys.
