Eagle Materials Inc. has selected thyssenkrupp Polysius to modernize and expand its cement plant in Laramie, Wyoming, World Cement reports.
Operating since 1926, the facility supplies cement to several markets, including northern Colorado, Nebraska, Utah, and Wyoming. The project will significantly boost the plant’s annual production capacity to approximately 1.1 million metric tons of cement while enhancing sustainability and efficiency.
The modernization initiative will integrate cutting-edge technology aimed at improving operational efficiencies. A key component is the installation of an alternative fuel substitution system, which aligns with Eagle Materials’ sustainability goals by incorporating lower-cost alternative fuels and natural gas. The project underscores the company’s commitment to environmental stewardship and cost reduction through advanced fuel use and energy efficiency.
Olivier Terver, President of thyssenkrupp Polysius North America, highlighted the comprehensive nature of the partnership:
“This project reflects our steadfast commitment to supporting our customers every step of the way. From maintenance services to green technology integration and full plant modernisation, we address both our customers’ evolving demands and our shared environmental responsibilities.”
The redesigned plant will prioritize safety and streamlined operations. The expansion will introduce a new finish mill to supplement the grinding capacity of the existing plant, which already features an integrated polysius® booster mill. The polytrack® ECO cooler will facilitate efficient heat recovery and clinker cooling, contributing to both process reliability and cost savings.
Key technical elements of the project include:
- Limestone Impact Crusher Circuit
- quadropol® Vertical Roller Mill
- Five-Stage Preheater
- Two-Pier Rotary Kiln with polguide® Drive System
- In-line Calciner
- polysius® Step Combustor for Alternative Fuels
- polytrack® ECO Clinker Cooler
With primary regulatory approvals secured, construction is set to begin immediately. The project is scheduled for completion in the second half of 2026. Once operational, the upgraded plant will bolster regional cement supply and contribute to Eagle Materials’ broader sustainability objectives.
