LAARMANN Roll Crushers are typically applied in laboratory or pilot plant applications after primary reduction of the infeed material. Roll crushers operate with a minimum of dust generation and produce a material with a tight size envelope containing a minimum of fines. Designed for rapid, controlled size reduction of ore, mineral or rock prior to metallurgical testing or further milling or grinding the LAARMANN LMRC Roll Crusher has is built with two off same diameter individually. Powered contra-rotating rolls, so the nipping process produces an ideal crushing environment for a wide variety of materials. Product sizing is controlled by an (adjustable) gap setting between the 2 rolls. One roll is heavy duty spring mounted as protection against uncrushable material attempting to pass between the rolls.
