Vibrating Grizzly Feeders & Grizzly Bars

ELRUS Hydraulic Grizzly Bars and Vibrating Grizzly Feeders work in conjunction with each other to remove oversize rock and fines from the primary crusher feed to optimize production and reduce wear and tear on equipment.

At the beginning of the sorting process, over-size material from pit run or shot rock loaded onto the Hydraulic Side Dump Grizzly is removed.  What passes through the grizzly bars lands in the hopper and falls onto the Vibrating Grizzly Feeder (VGF).  

The VGF, located at the bottom of the hopper, removes fine material like sand and small stone and provides a continuous rate of feed into the jaw crusher.

Hydraulic Grizzly Bars

A Hydraulic Grizzly can help your operation deal with the larger rock you encounter on your site. With its rugged construction, the Grizzly has been designed and engineered to exceed the demands of the toughest pit, quarry, and mine applications.

Not only is the Grizzly built to handle large feed rates of materials; it has been engineered and manufactured to withstand the extreme rigors of quarry life. The Grizzly bars have been designed for optimum separation efficiency while withstanding maximum punishment. They can be set according to the oversize material you need to remove in order to minimize damage and improve the overall performance of the crushing spread.

Vibrating Grizzly Feeders

Vibrating grizzly feeders remove fine material from crusher feed before it enters the jaw. No contamination within the crushing chamber promotes rock on rock crushing to increase efficiency and reduce wear on equipment.

As its name suggests, the feeder vibrates and this agitation causes the material to separate. This process, known as segregation, causes the small material (Fines) to sink to the bottom and the larger rock moves to the top. The segregation continues as the feed travels down the length of the VGF; by the time it reaches the fingers at the end, the fines are able to pass through the spacing, leaving only clear stone to enter the crushing chamber.

ELRUS Vibrating Grizzly Feeders feature heavy-duty construction and are designed to provide years of service under varying load and feed conditions.

I don't know about you, but Earle the Grizzly was SUPER STOKED when he heard about our Vibrating Grizzly Feeders. I've got a feeling he's not gonna be too thrilled when he finds out what they really do.
