Case Study

Less Time, More Tonnage: Discover Daanen & Janssen's Solution to Production Challenges

Location De Pere, Wisconsin
Industry Aggregates: Limestone Quarry

The Challenge

Daanen & Janssen, Inc. faced production capacity challenges with an older, less efficient crusher plant. The existing setup operated for 20 hours a day and consisted of a smaller 300-horsepower cone and dual king roll crushers, making it a cumbersome and costly operation.

Increasing production demands and stringent noise regulations necessitated a more efficient solution that could operate within tighter time

The Solution

In collaboration with Superior Industries and their dealer, Rock Machinery, Daanen & Janssen, Inc. utilized a new Superior Portable Plant consisting of a Tandem 7203 Guardian Screen Plant; a P400 Patriot Rear Feed Side Discharge Plant; and two PowerStacker® Conveyors.

 

This compact yet powerful solution met their needs for adaptability and mobility. The plant's design allowed for quick setups and teardowns, critical in contract crushing scenarios where moving between sites swiftly is crucial.

The Results

Daanen & Janssen, Inc. increased output by approximately 100 tons per hour, while reducing daily runtime from about 20 hours to under 14 hours. The operation now crushes more material with a single cone, significantly improving fuel efficiency compared to its previous multi-crusher spread.

 

This capability allowed Daanen & Janssen, Inc. to maximize uptime and efficiency, proving the plant’s effectiveness in a competitive contract crushing market and paving the way for further geographic and market expansion.
