Daily Knowledge of Fertilizer Production Line: Disc Mixer
The “Uniformity Master” of Fertilizer Mixing
The disc mixer is a core equipmentin fertilizer production lines for achieving highly uniform mixing of raw materials. With its unique disc structure and specially designed mixing blades, it can blend materials of different physical properties to over 95% homogeneity within short time (typically 2-5 minutes), recognized by IFA as one of “the most reliable mixing solutions”[1].
The disc mixer is an essential component in organic fertilizer production equipment, serving as the primary blending unit that ensures homogeneous mixing of various organic materials. In the fertilizer production line, it thoroughly combines raw materials like animal manure, crop residues, and microbial additives, creating a uniform mixture crucial for subsequent composting and granulation processes. Its unique disc design provides efficient mixing while minimizing damage to organic fibers, maintaining material integrity. The mixer’s ability to handle high-moisture content materials makes it particularly valuable in organic fertilizer production, where consistent blending directly impacts product quality and fermentation efficiency.
Why Choose Disc Mixers?
Vs Traditional Mixers
- 40-60% shorter mixing time
- 30-50% energy saving
- <0.5% residue (3-5% in conventional)
- 70% less maintenance
Technical Advantages
- 3D mixing (radial+axial+circumferential)
- Adjustable tilt angle (15-45°)
- Wear-resistant alloy liner (5-8 years life)
- Smart cleaning system
Operation Guide & Applications
Standard Operating Procedure:
- Pre-mix: Load ingredients (60-80% capacity optimal)
- Set: Adjust rotation speed (typically 15-30rpm) and duration
- Start: Begin at low speed (5rpm) for 30s before full speed
- Discharge: Control output via bottom pneumatic valve
| Fertilizer Type | Optimal Speed(rpm) | Mixing Time(min) | Uniformity Standard |
| Compound Fertilizer | 20-25 | 3-5 | CV≤5% |
| Organic Fertilizer | 15-20 | 5-8 | CV≤7% |
| BB Fertilizer | 18-22 | 2-3 | CV≤3% |
Ideal for: High-value fertilizers, micronutrient addition, microbial agent mixing where strict uniformity is required.
