Stephens MFG. is in the center of many coal producing states. We have build a lot of Magnetite Silos of various sizes and styles, and Magnetite Screws for over 35 years. We have also produced several conveyors of various sizes to handle moving coal to and from wash plants. When production and delivery dates have permitted we have also worked some with slump tanks, modular wash plants and some general repair and work on other coal related equipment.
