Working principle and advantages of cage crusher

2025/07/24

In the field of fertilizer production, the crushing link is an important part of ensuring product quality. When traditional crushers process fertilizer raw materials, they often have blockage problems due to the characteristics of the raw materials, which not only affects the production progress, but also increases maintenance costs. The emergence of cage crushers has brought efficient and stable crushing solutions to fertilizer production.

The cage crusher adopts a unique cage structure, which consists of an inner cage and an outer cage. Both the inner and outer cages are composed of staggered steel bars. Its working principle revolves around the multi-stage action of "impact-collision-shear". When the equipment is started, the inner cage rotates at high speed under the drive of the motor to form a strong centrifugal force field. The fertilizer raw materials enter the crushing chamber through the feed port and will first be impacted by the high-speed steel bars of the inner cage. This instantaneous impact force can quickly break the structure of the raw materials and achieve preliminary crushing. Under the continuous action of centrifugal force, the raw materials after preliminary crushing are quickly thrown to the outer cage. In this process, the raw materials will continue to collide with other steel bars in the inner cage, and each collision will further refine the particles. At the same time, because the steel bars of the inner and outer cages are arranged in an interlaced manner, when the raw materials move between the two, they will be subjected to strong shearing. This shearing force can effectively disperse the raw material particles that may stick together and ensure the uniformity of crushing.
In terms of performance, the cage crusher has significant advantages. It can effectively deal with raw materials that are prone to blockage of traditional equipment in fertilizer production, reduce downtime caused by blockage, improve production continuity, and reduce equipment wear caused by blockage, thereby saving maintenance costs. Whether it is an organic fertilizer production line or a compound fertilizer production line, it can be carried out stably and efficiently.
For fertilizer production companies, the cage crusher can provide strong support for companies to improve production efficiency and ensure product quality with its excellent performance. Choose a cage crusher to help fertilizer production achieve efficient, stable and low-cost operations!
