KAMEYO Roller Crushers are typically used in laboratory or pilot plant applications after the primary reduction of the infeed material. Roller crushers operate with a minimum of dust generation and produce 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. Powered contra-rotating rollers, 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 rollers. One roller is a heavy-duty spring mounted as protection against uncrushable material attempting to pass between the rollers.
