Concave ring for Powerscreen 1300

The concave ring, part number 603-141, acts as the stationary crushing surface within the cone crusher assembly. During operation, this component works in conjunction with the moving mantle to compress and fracture rock and aggregate materials. The specific geometry of the ring is engineered to define the crushing chamber profile, which directly influences the reduction process and the final particle size distribution of the processed material.

This component is compatible with the Powerscreen 1300 cone crusher. The part is produced to the 44 CB-GROSS specification, ensuring it meets the dimensional and profile requirements for this specific crushing unit. Proper fitment is necessary to maintain the integrity of the crushing chamber and to ensure the machine operates within its design parameters for volume and output consistency.

In cone crushers, the concave ring and the mantle form the primary crushing interface. As material enters the chamber, the movement of the mantle against the stationary concave ring reduces the size of the rock through compressive force. Regular inspection of the concave surface is required to manage the effects of abrasive wear, which can otherwise lead to reduced crushing efficiency and inconsistent product sizing.
