As with all jaw crushers, peak capacity is achieved under favorable conditions: dry, consistently-sized material fed at a steady rate without overloading the jaw. The K-JC 604 performs well on concrete rubble, asphalt millings, and natural stone when the upstream feed keeps pace with the crusher. Actual throughput varies depending on material hardness, moisture content, feed size consistency, and cycle time of the loading equipment. Evaluating the machine on your specific material during a demonstration is the most reliable way to set realistic production expectations before committing to a workflow.

Heavily reinforced concrete, wet cohesive material, or irregular oversize pieces will each reduce effective throughput and increase wear. If your material includes a high proportion of rebar or embedded steel, the onboard magnetic separator is doing critical work, and factoring in brief pauses for magnet clean-off is part of an efficient operating rhythm.
