It is a nemesis of hard materials such as ammonium, diammonium and urea,etc. The cage crusher is composed of frame, casing, big rat wheel set, small rat wheel set and two motors. When the machine workink, one motor drives the large cage to rotate smoothly,The other one motor drives the small cage to reverse rotation,the material enters the inner rat wheel frame through the hopper, The high speed rotating steel bar repeatedly impacts and breaks the material, so as to achieve the fine crushing effect. The machine has the advantages of simple structure, high crushing efficiency, good sealing performance, smooth operation, easy cleaning and convenient maintenance.
