McCloskey International has unveiled the new J4 jaw crusher, boasting powerful new features for hard rock applications. The J4 builds on the robust features of the existing design, while adding new productivity with an exciting line-up of features and options aimed at boosting productivity and offering enhanced durability across applications.
Designed to withstand the toughest conditions worldwide, the J4 delivers high production due to its innovative jaw chamber design and enhanced material flow. The large 1060mm x 700mm jaw opening accommodates large feed sizes, contributing to higher production in material processing.
The material path is enhanced with the grizzly pan feeder under the hopper that allows for better sizing of material with a variety of mesh options. The J4 also delivers industry-leading stockpiling, with wide main and side conveyors for enhanced material flow. The angle adjustable 1200mm wide ToughFlex main conveyor boasts a 3.912m high stockpile, and with quick release and ground level access, with the belt being easy to maintain and service. ToughFlex is constructed with a special weave of 2 fabric plies and an additional binder warp (without the need for steel wire) resulting in reduced belt weight.
While a side conveyor remains an option for many jaw crushers in its class, the J4’s integral folding conveyor is standard and has an 650mm adjustable sped belt fueling a stockpile height of 3.44m. In addition, the recirculation conveyor can be rotated 90 degrees to be used as a stockpiling conveyor.
The crushers are suited particularly to aggregates, construction and demolition recycling, and site preparation.
