Rock Engineered Machinery Company Inc., (REMco) was founded as a California corporation in 1983. It is one of the few remaining fully American owned crusher companies left in the United States. Manufacturing facilities and headquarters located in Livermore, California; REMco machines serve the needs of the construction material, mining, industrial mineral and growing recycling industries. At REMco, we understand that size-reduction equipment generates revenue for its owner, our customer. REMco crushers use top quality materials, and the latest design techniques. REMco builds the strongest, heaviest VSI. REMco crushers are not "throwaway" type machines. They are not copies of other manufacturers’ crushers and contain no “made in China” content. REMco VSIs are real crushers. They are not shaping devices. They crush and at the same time, produce the best shaped product. Most crusher manufacturers make a limited number of VSI models in fixed configurations, holding an ideology that one or the other is suitable for every crushing application regardless of the finished product or the characteristics of the material being crushed.At REMco, we are VSI guys. We offer VSI crushing expertise for any materials, any tonnage, anywhere. REMco tailors each crusher to a given task; no application is general in nature. 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. REMco as of 2014 is officially the authorized exclusive distributor for PROMAN. REMco is introducing the line REMco PRO-Series of PROcone and PROjaw crushers to all operators in North and South America. Offering the best REMco / PROMAN technical support, customer satisfaction has been very high.
