This coal crusher is a single stage, two roll crusher installed in a power plant. It was selected to replace a large hammer mill crusher that was generating too many fines for the coal fired boiler.
The crusher is processing a mix of PRB coal and Eastern Oklahoma coal at a rate of 850 TPH. The feed size to this unit is 3 inches with the occasional 5 inch lump. Product size is 1/2 inch. The coal crusher has only one drive motor and a single gearbox to provide power to both abrasion resistant, replaceable pin tooth rolls. The gap between the rolls is adjustable to allow for in-operation adjustments as needed. The entire unite has tramp metal relief to allow for large tramp metal to pass through the crusher without damage to the rolls or the drive system.
