GreyHawk Metso C3054 Portable Jaw Crusher, Unit #885

#1167/38072/2292

The Nordberg C3054 is an efficient primary jaw crusher for quarries, gravel pits, mines and recycling.

Mounting of the crusher is made without a bolted connection to the foundation. The main frame of the crusher is made of rolled steel side plates and two steel castings, connected through precision machined bosses and held together by large diameter bolts. The pitman and the front and rear frame castings are made from high-quality steel with excellent fatigue strength. There are no welded joints in the frame. The frame can be completely disassembled for transportation if necessary. The eccentric shaft bearings are long-life grease lubricated spherical roller bearings and are all of the same size.

The discharge setting is easy to adjust utilizing the push button hydraulic adjust, by means of moving wedges. The toggle plate operates on a rocking principle without any lubrication and serves as an overload fuse.

The crusher's jaw dies are of high-manganese steel castings, and the cheek plates of high abrasive-resistant steel plate. The jaw dies can be reversed for maximum utilization. Tools for jaw die changes are included with the jaw crusher.
