hammer crusher is a new kind of crusher which has been widely used recently in the industry of limestone crushing. It combines the traditional second crushing and compared with the jaw crusher and impact crusher it has advantages of high energy-saving, area-saving and low investment for once. So it is comparably advanced equipment in the current hammer crusher field. It adopts high production technology to carry out once shaping thus has the features of high efficiency and energy-saving. The product material can be adjusted according to the requirement and coarse, medium and fine material can all be got. No flake, no smoothness and multi edges and corners can guarantee the compression strength. So the product material is especially suitable for highway, construction and big project. Box hammer crusher eliminated the initial crushing of jaw crusher and is a new kind equipment of once crushing to small as well as big materials. It has high output, high efficiency, low power and can save manual and material power so as to reduce the crushing cost.     Working Principle:     Box hammer crusher can change the discharge size by adjusting the grate gap so as to meet the requirements of different customers. It has features of simple structure, high crushing ratio and high production efficiency, etc. And it can be two kinds of crushing: Dry and Wet. The main working part of box hammer crusher is the Rotator with hammer. Rotator is consisted of main shaft, round panel, pin roll and hammer. The rotator which is driving by the motor is whirling rapidly in the crushing cavity.     The material fed into the crusher from the feeding opening is hit, impacted, cut and grinded to be powder by the high speed hammer. Under the rotator, there is the screen plate. The material which is smaller than the size of screen mesh will be discharged out, while those which are bigger than the mesh size will be continually crushed and grinded by the hammer and will be finally discharged.     Features:     (1). Big feeding size. High fine crushing ratio and high efficiency;     (2). Simple structure. Compact equipped. Light weight;     (3). Even size. Little exceedingly-crushing powder;     (4). It has many advantages such as low electricity, easy maintenance, etc. So it is the ideal medium and fine crushing equipment.
