K-JC 805 Large Compact Jaw Crusher

K-JC 805 Overview

The K-JC 805 is Komplet America’s largest compact mobile jaw crusher, delivering high output while maintaining the maneuverability contractors expect from a compact machine. Designed to handle medium to hard rock, reinforced concrete, asphalt, and demolition material, the K-JC 805 is well suited for contractors, quarry operators, and recycling applications that demand consistent performance.

Despite its powerful crushing capability, the K-JC 805 remains easy to transport and capable of accessing tight jobsite conditions. The machine is engineered with excellent access to the engine and crushing chamber, simplifying maintenance and reducing downtime. For operators looking to increase production while cutting waste removal costs, the K-JC 805 offers an ideal balance of power, accessibility, and compact efficiency.

How much material can the K-JC 805 crush per hour?

The K-JC 805 is the largest jaw crusher in the Komplet lineup, rated at up to 160 US tons per hour. Powered by a 130 hp Tier 4 Final diesel engine with a 31” × 21” jaw inlet and weighing approximately 49,600 pounds, the K-JC 805 steps into semi-production territory, bridging the gap between compact contractor crushers and full-scale stationary plant equipment. It is built for high-volume C&D recycling operations, rock quarry processing, and larger demolition projects where sustained output over a full shift is the primary requirement.

The “up to” production rating refers to the maximum potential output a machine can achieve under ideal conditions—this includes consistent feed material (size, hardness, and moisture), skilled operator use, proper setup, and minimal downtime. For example, clean concrete with no rebar, fed at a steady rate in optimal weather, will produce higher output than mixed, wet, or irregular materials. Every job site is different, which is why we emphasize that this is not a guaranteed or average output, but a best-case scenario metric. If you’re unsure what output to expect for your application, we’re always happy to review your material and help you model realistic results.

At up to 160 tph, the K-JC 805 demands a feed operation scaled to match. A single small excavator or wheel loader will not keep the jaw consistently loaded at maximum capacity — this machine is sized for larger material handling equipment: a mid-size excavator, a high-capacity loader, or a primary feeder/grizzly arrangement. Actual throughput depends on material hardness, feed size consistency, moisture content, and the cycle time of the loading equipment. Operations considering the K-JC 805 should evaluate it on their specific material during a demonstration before building a production schedule around any particular output figure.

Like all jaw crushers, throughput drops with material hardness, high moisture content, and irregular feed. The K-JC 805 includes Komplet Connect for remote performance monitoring, which helps operations managers track shift production, identify bottlenecks in the feed cycle, and schedule preventive maintenance before issues cut into production time. The machine also includes an integrated side conveyor for discharge flexibility on congested sites.

Output size for the K-JC 805 ranges from approximately 1.2” to 4.7”, reflecting its larger jaw geometry and the heavier-duty materials it is designed to process. This range is well suited for primary crushing of quarry rock, large concrete demolition slabs, and hard stone — producing a coarser product that can be run through a secondary screen or impactor for further sizing. Operators requiring a more refined output should plan for a downstream screening or secondary crushing stage.

The K-JC 805 features the largest jaw inlet in the Komplet lineup at 31” × 21”. That opening accepts significantly larger feed pieces than the smaller jaw models, reducing the pre-breaking or pre-sizing work required upstream and allowing the machine to process large concrete slabs, bulky demolition rubble, and big quarry rock directly off the excavator bucket without intermediate reduction. As with all jaw crushers, consistent feeding within 80–85% of the inlet dimension optimizes throughput and jaw plate life.

On material type, the K-JC 805 handles the full spectrum of hard and abrasive materials: large concrete slabs and foundations, reinforced structural demolition rubble, natural hard rock including granite and limestone, asphalt, and mixed masonry. The onboard magnetic separator handles rebar and embedded steel continuously. For operations in rock quarrying, infrastructure demolition, or high-volume recycling processing, the K-JC 805 delivers production numbers that justify its classification as a semi-pro machine.
