UN-COALER® Bin Activator / Feeder

SILO

Where the 100% reclaim advantages of silo storage are employed, the UN-COALER® provides a cost-efficient and high-tonnage activating / feeder function. For example, a 70-foot diameter silo can be reclaimed with only four UN-COALER® units installed in line directly over the belt, providing rates up to 8000 TPH.

Mass flow design, coupled with high reliability and low installed cost, makes the UN-COALER® uniquely suitable for silo storage systems. Along with measurable performance advantages, the UN-COALER® also reduces operators’ expenses in operating and maintenance.

BARN

This 100% live reclaim facility maximizes the cost and operating advantages of UN-COALER® design. An entirely enclosed structure, the barn-type storage unit has sloping sides running the length of the building. A series of UN-COALER® units are located in the reclaim tunnel at the base, sized with up to 12 by 12-foot openings and spaced along the tunnel to produce the desired reclaim volume. Any percentage of material can be reclaimed simultaneously from any part of the pile.

In this and other tunnel applications with multiple units, the operator may include fixed and variable feed rates on the UN-COALER® to properly control blending and feed rate. Particularly in barn storage situations, the UN-COALER® units’ low headroom and total access from the tunnel facilitate structural and service efficiency. And for extremely long conveyor runs, the perfectly centered loading pattern virtually eliminates belt tracking problems associated with multiple discharge feeder systems.

Because the UN-COALER® is supported from the floor, structural considerations and suspended equipment costs are eliminated.

OPEN

The convenience and cost savings of open storage systems, either conical pile or windrow, are enhanced further by the unique installation advantages of the UN-COALER®. Lower headroom design and entirely free-standing floor mounting significantly reduce construction costs, concrete work, and tunnel depth. UN-COALER®’s straight line effective dust sealing, plus the option of explosion-proof motors and controls, minimizes dust hazards.

The windrow schematic illustrates the live reclaim efficiency of UN-COALER® installations. Eliminating rat-holing, bridging, and intersecting reclaim patterns assures maximum drawdown and reclaim rates with less equipment expense.

CRUSHER

Mounted directly above a crusher, the UN-COALER® units ‘low profile and straight-line design greatly simplify hopper and dust seal installation. With 100% linear feed rate adjustment, the UN-COALER® provides a constantly uniform discharge into the crusher, assuring maximum efficiency and extended wear life on the crusher elements.

A long, narrow discharge slot is ideal for even material distribution across the crusher inlet, again without expensive transition pieces or added height requirements. The gravity flow in-line concept reduces the crusher house size.

MOBILE

As an alternative to more costly bucket reclaimers, the mobile rail-mounted UN-COALER® produces high volume results with less equipment investment. Here, a wheeled or track-mounted loader scoops material into tandem UN-COALER® units mounted on a rail vehicle. The loader and UN-COALER® move along the full windrow length, working as a high-volume reclaim system. A fixed conveyor is located between the rails where direct vertical discharge from the UN-COALER® produces even feed rates and belt loading.

The economy and reliability of this system, which permits coal handling at less cost per ton, is made possible only by the unique structural and operating advantages of the UN-COALER® unit.

HOPPER

As unit trains or dump trucks deposit enormous quantities of material into large hoppers, the UN-COALER® provides the capacity and feed rate control necessary to distribute it efficiently. The large rectangular opening of the UN-COALER® mounted directly over the conveyor assures maximum drawdown.

The UN-COALER® is equipped with infinitely variable drive systems, permitting direct response to computer load cell or belt scale signals, affording automatic and exact proportioning or blending.
