Double Roll Crushers. Double Roll Crushers provide a 4 1 reduction ratio. They are typically used as a secondary or tertiary crusher for materials such as ROM coal with refuse, limestone, gypsum, trona, shale, bauxite, oil shale, clean coal, coke, salt, quicklime, burnt lime, glass, kaolin, brick, shale.Jaw crushers are typically used as primary crushers because they can take large and variable sized feed material, so the original feed won’t have to be blasted down to a fine size. Powerscreen jaws are designed to be significantly reliable and have lower wear rates, maximizing production and minimizing wear parts.
