Upper main frame consists of a threaded cap and houses the precision manganese steel concave. A threaded connection provides an accurate means of adjusting the crusher set.
Head is the shape of a cone segment with a pitch of 45°. A pan-shaped manganese steel mantle is bolted onto the head core.
Spindle consists of a rugged steel shaft that rotates on taper rolling bearings mounted on the inner cylinder and the lower main frame.
Spindle drive is composed of the spindle pulley, motor pulley and V-belts.
Wear parts are of manganese steel designed for metal to metal fit against the head surface and the upper main frame surface.
Clearing between operations is convenient and complete, salting of samples is eliminated.
