A Cage Crusher (WLF Series), also known as a cage bar pulverizer or cage mill, is a high-efficiency fine crushing machine engineered around the impact crushing principle. Utilizing counter-rotating concentric cage bars inside the crushing chamber, it rapidly pulverizes brittle and medium-hard bulk materials into uniform fine particles, making it essential for organic and compound fertilizer production lines.

A Cage Crusher (WLF Series), also known as a cage bar pulverizer or cage mill, is a high-efficiency fine crushing machine engineered around the impact crushing principle. Utilizing counter-rotating concentric cage bars inside the crushing chamber, it rapidly pulverizes brittle and medium-hard bulk materials into uniform fine particles, making it essential for organic and compound fertilizer production lines.
2. How does Cage Crusher work?
Raw materials are fed into the center of the inner cage through the feed hopper. Driven by two independent electric motors (total power ranging from 26 kW to 52 kW) at a rotating speed of 1000 r/min, the inner and outer cages rotate in opposite directions at high velocity.
As materials are flung outward by centrifugal force, they undergo intense, multi-stage impacts and shearing forces from the high-speed steel cage bars. The pulverized particles pass through the gaps between the outer cage bars and discharge smoothly from the bottom outlet, achieving a continuous throughput of 2–3 t/h (WLF650) up to 5–8 t/h (WLF1000).
3. Advantages of Cage Crusher
- High Impact Crushing Efficiency: Counter-rotating dual cages double the relative impact velocity, resulting in superior crushing ratio and uniform fine particle distribution.
- Non-Clogging & Easy Cleaning: Screenless bottom structure prevents sticky or damp fertilizer materials from clogging, with a quick-open housing for fast maintenance.
- Wear-Resistant Alloy Cage Bars: Cage bars are manufactured from high-strength, wear-resistant alloy steel to withstand continuous high-speed impact and extend service life.
- Smooth & Balanced Operation: Precision-balanced rotor cages ensure low vibration, stable operation at 1000 r/min, and compact installation footprints (from 1800×1300×1160 mm to 2400×1350×1560 mm).
4. Application of Cage Crusher
- Compound & Organic Fertilizer Plants: Fine crushing of urea, ammonium phosphate, potassium chloride, and dried organic compost clods before granulation.
- Chemical Industry: Pulverizing crystalline chemicals, salts, and medium-hard industrial raw materials.
- Mining & Building Materials: Fine grinding of limestone, gypsum, coal, clay, and brittle minerals.
- Feed & Agricultural Processing: Size reduction of mineral feed additives and agricultural raw materials.
