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-grain crushing technology have been available globally. We are currently manufacturing REMco VSI crushers in South America, Asia, and India in addition to the U.S. production at REMco’s California headquarters. The all the product design, development, and manufacturing is done in Stockton, CA, for the 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 the performance and durability of VSI crushers.

Over the years as our patents expire, we’ve seen our competitors quickly adopt our technology (their adoption is a genuine 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.
