Your Sand Professionals Since 1983

Rock Engineered Machinery Company Inc., (REMco) was founded as a California corporation in 1983 by three rock processing professionals who saw a need in the market for knowledgeable and experienced vertical shaft impact (VSI) crusher manufacturers. They banded together, and REMco was created. Headquartered in Stockton, CA REMco continues the proud tradition of American manufacturing.

Since 2000, the REMco VSI crusher product line and fine crushing technology have been available globally with the onset of the manufacture of REMco VSI crushers in South America, Asia, and India in addition to the U.S. production at REMco’s California headquarters. The product design, development, and manufacturing are done in Stockton, CA for Global distribution of REMco crushers.

As the leader in VSI performance and technology, REMco has expanded the application range of the basic VSI crusher. We’ve held more than 45 patents worldwide for our unique and innovative features that have strengthened VSIs performance and durably.

Over the years as our patents expire, we’ve seen our competitors quickly adopt our technology (their adoption is a true compliment to our innovation). Our advances have lowered crushing costs, raised production rates, and resulted in superior performance and reliability. REMco, as a leader in VSI performance technology, has expanded the application range of the basic VSI machine.

REMco crushers are highly versatile and span multiple industries, including construction materials, mining, industrial minerals, and recycling. This versatility is because our machines reliably and continuously produce cubical, well-graded, sound, mid-range aggregates, specification and specialty sands, and other fine sizes.

We understand that the whole point of our machines is to generate revenue for its owner, our customer. This idea is the core of what we do. Our crushers use top quality materials and the latest design techniques. We provide the best possible technical support to achieve customer satisfaction while attaining the lowest crushing cost per ton. REMco is unique in guaranteeing the performance of our machines in writing. We can do this because our crushers are tried, tested, and proven at the Stockton facility, which houses a complete materials test crushing facility.
