Abstract
Abstract ABSTRACT OF THE DISCLOSURE An elongated gravel crushing plant comprising portable lengthwise adjacent first and second reduction sections each having a material receiving and classifying unit at its rear and crushing means located forwardly of said unit. A delivery conveyor under the crushing means on each section extends forwardly and upwardly therefrom. The conveyor on the first section feeds crushed materials into the material receiving and classifying unit on the second section, and the delivery conveyor on the second section discharges the final product of the two sections at a high level discharge zone at the front of the plant. Crushed materials of different size classifications can be withdrawn from the plant at a multiplicity of stations thereon rearwardly of the final product discharge zone.
