How much material can the K-JC 704 crush per hour?
This unit will crush up to 90 tons per hour, however your output production will depend on specific material types, material sizes, desired output sizes, and the overall setup and operation of the machine.
Many variables can affect the actual production rate, including:
Material Type: Different materials have different densities and properties, which can impact processing efficiency.
Material Size: The size of the input material can affect the machine’s performance. Larger pieces may require more time to process.
Desired Output Size: The finer the output size, the longer it can take to process the material.
Operation Setup: Proper setup and maintenance of the machine are crucial for achieving optimal performance.
What does “up to tons per hour” really mean?
What size can the K-JC 704 crush down to?
Output ranges from approximately ¾” to 3¼”, adjustable via the closed-side setting using the wireless remote. This makes the 704 PLUS versatile across a range of end-product requirements — from coarser sub-base material to finer recycled aggregate. For operators targeting a specific DOT-spec gradation or clean separated fractions, pairing the K-JC 704 PLUS with a Kompatto screener downstream creates an efficient crush-and-screen circuit on a compact footprint.
What type and size of materials can the K-JC 704 process?
The K-JC 704 PLUS accepts feed material sized to fit within its 27” × 16” jaw inlet — one of the larger inlet openings in the compact crusher category. Feeding material consistently at 80% of that inlet dimension keeps the jaw cycling cleanly and prevents bridging or stalling. The larger inlet compared to the K-JC 503 and K-JC 604 means fewer pieces need to be pre-broken before feeding, which reduces pre-processing time and keeps production moving on demolition sites with large, irregular rubble.
On material type, the K-JC 704 PLUS handles the full range of standard C&D recycling and quarry processing applications: concrete (plain and reinforced), asphalt, brick and masonry, natural stone and quarry rock, and mixed demolition rubble. The built-in magnetic separator removes embedded steel and rebar from the product belt continuously, keeping the output clean without manual intervention.
