has been in business since 1965. Since that time, it has been totally committed to the crusher business. P.R. Engineering is one of the few companies in the world today which not only designs and manufactures the Birdsboro Buchanan line of crushers, but specializes in the complete refurbishing, repairing and supply of parts and service to all makes and sizes under its own roof. Its close working relationship with Metso, FFE Minerals and other innovators in the industry gives P.R. Engineering the label of being a truly one stop crusher shop.
