The vertical TMR mixer (Vertical Mixer) is a feed mixing equipment that operates on the principle of vertical stirring. It primarily relies on the rotational movement of spiral augers or blades in a vertical direction to achieve cutting, kneading, and mixing of feed. Compared to horizontal mixers, vertical models offer unique advantages in fiber feed processing, energy efficiency, and mixing uniformity, making them particularly suitable for small to medium-sized farms or diets with a high proportion of roughage.
I. Core Features of Vertical TMR Mixers
1. Structural Components
Vertical mixing chamber: Cylindrical or conical design to minimize feed residue.
Spiral auger/blades: 1-2 sets of vertical spirals, with some models featuring adjustable blades.
Power transmission: Typically driven by a tractor PTO (Power Take-Off), with some electric models available.
Discharge method: Hydraulically controlled side-tipping or bottom discharge gate.
2. Working Principle
Cutting and kneading: The spiral blades aggressively tear long-fiber feed (e.g., hay, silage) during rotation, improving palatability.
Mixing method: Feed circulates vertically, preventing stratification and ensuring uniform mixing.
3. Advantages and Applications
| Advantages | Applications |
| ✔ High mixing uniformity, reduces selective feeding | ✔ Ruminant feeding (dairy/beef cattle, sheep) |
| ✔ Excellent fiber cutting, improves digestibility | ✔ Diets with high roughage (hay, straw) |
| ✔ Lower energy consumption (20%-30% more efficient than horizontal mixers) | ✔ Small to medium farms (50-500 head) |
| ✔ Minimal residue, easy to clean | ✔ Budget-conscious users prioritizing mixing quality |
II. Vertical vs. Horizontal TMR Mixer Comparison
| Comparison | Vertical TMR Mixer | Horizontal TMR Mixer |
| Mixing uniformity | Excellent (ideal for fibrous feed) | Good (better for high-concentrate diets) |
| Cutting capability | Strong (vertical tearing action) | Moderate (relies on horizontal blades) |
| Capacity range | 3-15m³ (small to medium farms) | 5-30m³ (large-scale farms) |
| Energy consumption | Lower (80-150HP PTO required) | Higher (typically 150-300HP) |
| Maintenance cost | Lower (simpler structure) | Higher (bearings/chains wear faster) |
| Price | More economical (¥50k-200k for domestic models) | Higher (imported models can exceed ¥500k) |
III. Key Factors When Choosing a Vertical TMR Mixer
1. Capacity Selection
50-100 cattle: 5-8m³
100-300 cattle: 8-12m³
300+ cattle: Consider horizontal or large vertical models (12-15m³)
2. Power Requirements
80-150HP tractor: Suitable for 5-10m³ models
150HP+: Required for large vertical mixers (10m³+)
3. Blade and Auger Design
Adjustable blades: Adapt to varying fiber lengths
Wear-resistant materials (e.g., manganese steel blades) for extended durability
4. Smart Features (Optional)
Weighing system: Electronic scales for precise ingredient ratios
Data logging: Store recipes for optimized feeding management
IV. Recommended Brands and Models
1. International Brands
Kuhn (France): ProfiLine series, superior mixing uniformity
Jaylor (Canada): Patented spiral design, low residue
Storti (Italy): Heavy-duty vertical mixers for large farms
2. Domestic Brands
Wuzheng: Cost-effective with reliable after-sales service
Huaicheng Livestock Equipment: Smart weighing + hydraulic discharge
Muyang: Wear-resistant blades for high-fiber diets
V. Maintenance and Troubleshooting
1. Routine Maintenance
Clean residue: Remove leftover feed after each use to prevent mold
Lubricate bearings: Weekly inspection of spiral shaft lubrication
Blade inspection: Check for wear monthly and replace as needed
2. Common Issues & Solutions
Uneven mixing → Check blade wear or overloading
Starting difficulty → Inspect PTO drive or hydraulic system
Leakage → Replace aged sealing rings
Conclusion
Vertical TMR mixers, with their strong fiber processing, uniform mixing, and low energy consumption, are ideal for small to medium farms or high-roughage diets. When selecting a model, consider farm size, power compatibility, and smart features, while regular maintenance ensures long-term performance.
