CEMENTING ITS POSITION

摘要

Rock reduction plants, which process rock into products such as cement or sand, require specialty electrical construction that only a handful of electrical contractors have taken on. One such contractor, Farnham Electric Co. of McMinnville, Ore., does this work around the world. In 2009, the company completed a portable rock crusher and conveyor belt for Hawaiian Cement, Maui Concrete and Aggregate Division. The 3,000 feet of conveyor belt and portable rock crusher is one part of a mile-long system that transports tons of volcanic rock from the quarry to the plant where the rock is processed into cement and other products. Farnham Electric was established in 1920 and has specialized in rock reduction plants since the mid- to late 1960s.
