McCloskey J45/J45R Jaw Crusher

The J45 and J45R high capacity jaw crushers feature a true 1140mm (45″) x 688mm (27″) jaw. With both level and load sensors the J45 ensures the most efficient material handling across applications. The J45 features a heavy duty bofar design and pan feeder chutes with steeper angles to reduce material sticking.

Both the J45 and J45R boast a high capacity hopper with close to 6m³ (8 yd³) capacity. The main conveyor features easy access heavy duty skirting and are closer to the ground level for ease of access and maintenance.

The J45R offers the versatility of a recirculating system to product a crushed and screened final product with one machine. Alternatively, J45R’s return conveyor can be radialed to the side to stockpile rather than feeding back into the hopper.

Rugged and versatile, the J45 and J45R offer the field-tested reliability required for the toughest projects around the globe.
