Triton Coal Company
Gillette, Wyoming

We were contracted to design, furnish, install and commission a coal unloading, slot storage, reclaim and batch weigh train load out system. It consisted of a truck dump station with a 535 ton hopper capable of accepting 240 ton dump trucks with material size of 8" x 0". The hoppers feed two 90" wide feeder breakers rated at 2000 tph each. The feeder breakers feed a transfer conveyor, which transports the coal to the crusher station. A 4000 tph roll crusher reduces the material to 2" x 0". The material is then fed to a 60" wide, 7000' long overland conveyor rated at 4000 tph. The overland conveyor feeds a 72" wide tripper conveyor. The tripper conveyor fills a slot storage coal barn with a capacity of 50,000 tons. Coal is reclaimed from the storage barn with 26 vibratory feeders with a rated capacity of 800 tph each.

The vibratory feeders feed the load out conveyor rated at 6000 tph, which in turn feeds, the batch weigh load out system. The batch weigh load out system incorporates a 300-ton surge bin and a 140-ton weigh bin to load unit trains. A Programmable Logic Controller (PLC) and Operator Interface Terminal (OIT), located in the load out structure, control the entire system from tuck dump to load out system. Ancillary systems include dust collection, washdown and sample system.
