Increased finished grinding/distribution capacity at CA cement plant.

Glendora, CA, March 26, 2019 (GLOBE NEWSWIRE) -- CalPortland announces the commissioning of a new finish cement grinding mill and distribution system at its Oro Grande, CA cement plant. The project is the culmination of the partial plant modernization program that was originally completed in 2008, prior to the acquisition of the facility by CalPortland. The Oro Grande cement plant was purchased from Martin Marietta Materials, Inc. on September 30, 2015.

“The addition of this modern finish mill and efficient distribution system allows the plant to operate to the best in class standards as originally designed. It will help provide the industry with the additional supply required for necessary rehabilitation and rapidly developing infrastructure in CA and NV,” said Steve Regis, Senior Vice President Corporate Services, CalPortland.


The new mill restores shipping capacity of the Oro Grande plant to its original design. This development brings an additional 64 percent in total production capacity directly to the Oro Grande plant which provides several types of cement to the CA and NV construction markets. The $58.5M project includes the construction of the finish ball mill and two new cement shipping lanes with two new distribution silos.

The project began in January 2018 and was constructed by general contractor Thyssen Krupp (tkIS) and sub-contractor TIC (The Industrial Company), in collaboration with CalPortland’s Engineering Services team. It has provided local employment for 240 workers at the peak of project construction.

The mill is a Polysius two compartment mill with production capability of 200 short tons per hour. It is equipped with the most advanced and efficient motor, mill and separator technology as well as the most efficient cement cooler design technology. The system also employs mechanical conveyance (bucket elevator) to convey finished product to the new silos, reducing an additional 500 HP of energy requirement. These additional systems are being added to the Oro Grande facility, which is one of the most recently modernized and efficient cement plants in the United States.
