Working Principles Behind Extra Heavy Duty Vibrating Grizzly Feeders

Built from extra heavy-duty parts, with materials that are as durable as they are flawlessly designed, vibrating grizzly feeders chew their way through first-cut discharges of boulder-like rock. Its frame is steel-reinforced, made from I-beams that support a vibrating frame. Strangely enough, that frame doesn&#;t come in contact with the feeder bucket; there&#;s a group of hard, flexible buffering blocks inserted between that support table and the bucket.

An Extra Heavy Duty Break Down

The equipment is heavy and hard to take apart, so we&#;ll employ a virtual viewpoint. Four solid steel I-beams keep the grizzly feeder stable. On the far side of the sloped enclosure, two vibratory motors work asynchronously with massive springs to oscillate the large frame. Inside, while the motors are performing their vibratory duties, the eccentrically mounted motor shafts work in tandem, but their graph-plotted vibrational waveforms illustrate a counterbalanced system of operation.

Shock Load Handling Feature

The carbon steel frame is hard but not brittle, flexible but not malleable, and it&#;s about to swallow tonnes of rock-hard matter. It&#;s abrasive, this high-volume, high-velocity load, and it&#;s hitting the hardened metal hard. Essentially, these blocks of coarse matter would quickly choke a standard feeder, but the counter-oscillating vibrations delivered by the two off-centre motor shafts ensures a constant, consistent feed rate. Slipping and sliding on the frame funnel, the heavy-duty stream moves unhindered.

The Cross-Member Screening Principle

Other feeder types use vibrating motors and strangely configured shafts, plus a toughened bucket, of course. Still, extra heavy duty grizzly feeders have another trick up their sleeve. There are bars arranged in parallel inside the stream channel. Those toughened bars are utilized after the shock load has vibrated past the primary enclosure. In here, the bars act as crude but highly effective screens. They filter the rocks, nudging them forward towards increasingly wider grizzly bar openings. Dropping through the wider bars, the smaller rocks skip past the crusher stage while the oversize material moves inescapably into the crushing maw.

In simple to interpret terms, extra heavy duty vibrating grizzly feeders combine a shock load handling feature, an off-centre choke prevention mechanism, and a crude screening system. There&#;s a pan at the bottom of the machine, an open-topped vibrating frame up top, and a series of reinforced supports holding the whole package in place. Following a rubble-like stream, all while illustrating the equipment&#;s operating principle, it&#;s the grizzly bars inside the frame that separate the oversized rocks from the smaller material stream. That oversize is dealt with by a set of crushing jaws.
