Cedarapids CRJ3255

The new Terex® Cedarapids CRJ3255 plant combines the popular JW55HD jaw crusher with a high stroke, 52” x 20’ (1321 x 6096 mm) vibrating grizzly feeder resulting in a high production portable crushing machine. The CRJ3255 is built tough, including a new hopper design, to handle severe primary crushing applications. The highly mobile CRJ3255 is easy to operate and maintain and offers new levels of reliability and convenience. The jaw crusher features the latest improvements such as wedge release jaw faces and fully hydraulic wedge jaw crusher setting. The tail of the product conveyor lowers for operation, maximizing clearance under the jaw crusher. The conveyor discharge height adjusts to reduce material impact on the receiving conveyor. Multiple options are available, allowing customers to configure the CRJ3255 to meet specific needs.
