CRUSHING
TERTIARY CONE CIRCUIT
DELIVERS MORE OUTPUT, LESS RECIRC A US quarry operation has recorded some very strong results since it upgraded its tertiary plant to incorporate a late model cone crusher.

aintaining optimum yield from any cone crushing circuit is ultimately achieved by combining the latest cone crushing technology with solid application expertise and highly responsive equipment life cycle management. The latter is essential when finetuning a crushing circuit for peak performance – and it’s best driven by an ongoing producer/equipment manufacturer “partnership” that ensures the highest production capacities and the lowest percentage of recirculating loads. Circuits with high recirculating loads eat up more capacity and horsepower in the crusher,
while also increasing wear – and unnecessary recirculating loads send saleable material back to the crusher rather than to the finished product stockpile. Minimising recirculating loads is an imperative for producers such as the RiverStone Group, which operates 15 active quarries throughout Iowa and Illinois in the United States. As a family-owned business since the late 19th century, the company prides itself on pushing the envelope in productivity and innovation. RiverStone is known for its abundance of Class A quality stone products which meet stringent US

Department of Transportation and Federal Aviation and Administration quality assurance standards. At its Colona, Illinois-based Cleveland Quarry, RiverStone upgraded its plant with higher capacity primary and secondary crushers. For an optimum yield of finished product at its tertiary circuit, the company installed a P600 Patriot cone crusher manufactured by Superior Industries. The result has been greater plant uptime, longterm efficiency, reduced wear costs, minimal recirculation load, and increased production capacities at lower costs per tonne. Delivering
