North Central Aggregates: DOT-Spec Expansion

Case Study

Expanding Market Territory with Compact Closed Circuit Cone Crushing Plant

Location Concord, Michigan

Industry Aggregates: Sand & Gravel

The Challenge

North Central Aggregates (formerly Iron River Sand & Gravel) was looking to expand its operations into southern Michigan to tap into new markets with stringent DOT specifications. The expansion required a highly versatile and compact crushing solution that could handle different types of rock deposits and fit into tight spaces without sacrificing production capacity.

The Solution

In collaboration with Superior Industries and their dealer, Rock Machinery, North Central Aggregates utilized the Superior Portable P300 Patriot® Cone Closed-Circuit Plant.

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

The portable cone plant proved to be a high-performer, delivering up to 300 TPH of pure stone production despite encountering the hardest stone the team had ever processed.

It also enabled the production of two different dense grade DOT spec materials simultaneously at rates up to 500 TPH.

This capability allowed Iron River 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.
