In the field of fertilizer size reduction, the cage crusher stands as a master blacksmith among fertilizer equipment. This robust fertilizer machine wields its dual-rotation cages like hammers, expertly designed to tame the most stubborn materials. Whether crushing rock-hard MAP/DAP or breaking apart caking-prone urea, this essential fertilizer production machine effortlessly transforms hardened granules into a uniform, valuable powder, ensuring optimal quality and efficiency in any production line.
The Philosophy of Counter-Rotating Cages
Dual Rotation
Outer cage rotates clockwise while inner cage spins counterclockwise, creating 60-80m/s relative shear forces
Multi-Stage Impact
Materials endure 10-15 crushing cycles between high-speed steel bars
Dynamic Classification
Properly sized powder exits through cage gaps, preventing over-grinding waste
Self-Cleaning
Centrifugal force automatically removes adhered materials
“Traditional crushers wear out quickly processing MAP—requiring monthly hammer replacement—while our cage crusher’s alloy bars last 2000 hours, reducing maintenance costs by 70%. This is the economic solution for hard fertilizer crushing.” — Equipment Supervisor, Compound Fertilizer Plant
Four Unmatched Advantages
| Advantage | Technology | Value |
| Hard Material Specialist | Special alloy bars + high-speed design | Crushes mineral fertilizers ≤Mohs 5 hardness |
| Uniform Fineness | Dual counter-rotation + dynamic grading | 90% product in ideal 0.2-0.5mm range |
| Energy Efficient | Precise impact replaces full-power grinding | 30-40% energy saving vs traditional models |
| Low-Dust Operation | Fully enclosed structure + negative pressure | Workspace dust ≤10mg/m³ |
Typical Applications
- High-hardness Fertilizers: Pre-processing MAP, DAP, CAN etc.
- Compound Fertilizer Rejects: Re-crushing off-spec granules
- Organic-Mineral Blends: Ensuring particle size compatibility
- Specialty Fertilizers: Providing base powder for CRFs
Within a complete suite of equipment required for biofertilizer production, the cage crusher plays a vital preparatory role. This robust machine is tasked with the primary size reduction of organic raw materials, ensuring a uniform, fine powder. This optimal particle size is critical for the subsequent mixing, composting, and granulation stages, making the cage crusher a fundamental piece of equipment for efficient and high-quality biofertilizer manufacturing.
