Trommel Screen
Trommel screen uses a rotating drum and a rolling brush device to create a spiral motion for material, allowing for precise and fine grading. This makes it an ideal solution for the high-volume, high-precision screening of compound fertilizers.
- Precise grading The optimized length-to-diameter ratio and screen mesh aperture of the drum ensure uniform and precise particle grading. 
- Reduced blockages The drum uses an anti-corrosion screen mesh and is equipped with an automatic cleaning device to reduce blockages and vibration. 
- Efficient for fertilizers The screen mesh and beating device are optimized for the specific characteristics of compound fertilizer granules, ensuring easy discharge and quick grading.
