The Spyder 514TS is a patented track-mounted, reverse screening plant designed for primary or secondary screening of rock, sand & gravel, soils and other materials. Its 5'-0" x 14'-0" (1.5 m x 4.3 m) double-deck screen is capable of producing three finished products simultaneously. The versatile 514TS can be used as a stand-alone screen or in conjunction with a crusher to easily recirculate oversized material back into the crusher for further reduction.
