Feed bins and surge bins

Feed/Surge Bins

surge bins diagram

The primary function of this surgebin is to provide the operator with a controlled constant feed to the secondary without taking on the wear & tear of operating a belt feeder associated with the larger sized rock, and yet maintain the required mobility for small projects.

In the basic skid mounted format the unit does not have to be dismantled for moving and can be wired with plug & socket to eliminate the need for hard wiring on every site.

The flat bottom of the hopper provides a rock-on-rock target for the feed conveyor this eliminates the high wear associated with feeding bins with conveyors even if the feed drops frequently and the bin empties.

The skids can be placed on concrete or wood cribbing, optional bolt on extension plates sloped or vertical can be added to provide extra capacity when required.

This surgebin provides maximum versatility for the modern operator combining large rock handling ability with maximum portability.

This unit has been successfully installed into processes after the primary crusher, after the secondary crusher, and finally for feeding a sand & gravel operation.

The ETG designers are used to working in the New England quarrying environment. We believe it is one of the harshest in the USA and places unique demands on all equipment and materials used in the processing of local rock products.

We have built on this experience to design structures that reflect the typical hard rock found in this area and every structure is constantly being modified to utilize modern materials and the latest proven technology.

It maybe possible to purchase a surgebin that is cheaper, however, we would challenge the design and construction if it does not match the ability of this product to resist the constant wear and tear undertaken in the processing of typical New England Hard Rock that puts every piece of equipment in use in New England area on a self destruct mission that we guarantee to delay by design.

The standard hopper heaped = 15 cubic yards or 20 tons.

The vertical extension plates = 7 cubic yards or 9-1/2 tons extra capacity.

The sloped extension plates = 9 cubic yards or 12 tons extra capacity.


The noted capacities are based on 100# per foot3 and the ability to fill the cavities.

The width of the 24" sloped extension plates increase the width of the upper hopper to 12' 2" in both directions therefore it would normally be removed for transportation between sites.
