Looks like a variation on the old "Bin Activator". ■

Your picture appears to be a STOCKPILE vibro ring feeder......pile activation type feeder to help move material down thru a hole in a shed, typically pushed into drop hole by BIG WHEEL LOADERS.

G-K, or General Kinematics makes this type of feeder i believe.

STOPS RAT-HOLING of the pile....activates material to fall into the HOLE down into and onto a belt conveyor say for a ship loader conveyor for example. ■

This sketch is indeed that of a Bin Activator - made by many Powder handling and feeding suppliers - Vibra Screw Inc , USA, Brabender ,Germany . Many local variants are available in other countries too .

The suspension arrangement looks too elaborate . A simple suspension from the bin with flexible ropes and a flexible bellows connection between the bin botom and the activator to prevent material spillout is usually sufficient .

There should be sources in Bulk Handling Directory as well . ■

To be precise, it's a General Kinematics "Un-coaler"

It is indeed. I never used them: but then again I never used such shallow hopper angles either. I mean to say..! Rattling good fit between the soffit edge and the quivering bin shell; methinks. They never illustrate these gadgets from the side though, do they?■

That is indeed a General Kinematics Uncoaler/Bin Activator. If you want more literature on it please let me know and I can send it to you. We have had many installations throughout the world and have had very few problems with it.

General Kinematics UN-COALER combines two feeders and a pile activator into a single, low headroom unit, significantly reducing both tunnel width and height requirements. This reduction in tunnel size provides considerable cost savings during construction, while maintaining access for inspection and maintenance.

The UN-COALER activator / feeder is combines the material delivery of tandem enclosed feeders with integrated pile activation, all driven by a single, low horsepower vibratory drive. Precise flow control can be adjusted electrically through a VFD, or pneumatically using General Kinematics Variable Force (VF) wheels. Since the unit discharges material vertically to the conveyor below, loading is always centered and symmetrical. This feature helps to eliminate belt tracking problems common to side feeding. The UN-COALER also helps eliminate bridging and issues found with other bin or pile activators, using significantly larger hopper openings to the material pile. Standard and specially engineered sizes are available.

I would be interested to know where you came across our diagram, as it is not on our website. ■

The arrows indicate a vibrational force that "activates" the pile and allows it to move freely downward. These are good for activating and metering coal piles where the coal wants to bridge. ■
