Cage crusher has better crushing effect on materials with high hardness and is suitable for crushing various single fertilizers. There is a fixed steel plate on the cage crusher. There are 2 to 3 circles of cage bars on the steel plate. The cage bars are arranged on the steel plate in a concentric circle. The cage bars on the two steel plates are staggered on the machine, which is conducive to the uniform crushing of materials. Each steel disc and the cage bar fixed on it constitute a cage. The two cages rotate backward under the driving axle of each cage. When the material enters the center of the cage from the inlet port on the upper part of the shell, it first falls into the inner ring. After being attacked by the high-speed rotating cage bar, it is thrown down to the next ring under the action of centrifugal force and smashed again by the layer cage bar. Material is attacked by cages at all levels and finally crushed.
The cage crusher has simple structure, good crushing performance and strong sealing. It is especially suitable for crushing materials with high humidity (moisture less than 40%). But he also has the drawbacks of easy wear and high energy consumption.
