1. Overview
In standardized feed production, different animals (poultry, aquatic creatures) and their growth stages demand feed particles of specific sizes—large pellets must be crushed into uniform fine particles to ensure palatability and nutrient absorption. The Roll Type Feed Pellet Crusher is a specialized device engineered for this critical process, breaking large feed pellets into consistent small particles through roller extrusion, shearing, and tearing.
Available in double-roll and three-roll configurations, with optional coarse or fine tooth rollers, it produces particles ranging from 0.6-1.5mm (fine teeth) to 1-2.5mm (coarse teeth). It serves as a key link in feed production lines, widely used in feed factories, intensive breeding bases, and aquatic feed processing plants to meet diverse granulation needs.
2. Core Features
2.1 Precise & Uniform Crushing
Equipped with differential speed rollers (e.g., 725r/min for quick rolls, 475r/min for slow rolls), the crusher generates strong shearing and tearing forces between rollers. This ensures feed pellets are crushed evenly—free of excessive powder or unbroken lumps—with particle size uniformity exceeding 95%. This precision is vital for poultry chicks and aquatic fry, which rely on consistent particle sizes for digestion.
2.2 Flexible & Adaptive Design
- Adjustable Particle Size: Replace rollers with coarse teeth (1-2.5mm output) for adult poultry feed or fine teeth (0.6-1.5mm output) for chick/fry feed, adapting to different growth stages.
- Bypass Device: A built-in bypass system lets uncrushed pellets skip processing, improving production flexibility for mixed feed batches.
- Easy Roll Spacing Adjustment: The Y160M-4 model features a specialized spacing adjustment device, enabling precise fine-tuning of particle size to match raw material variations.
2.3 Stable & Efficient Operation
- Compact Structure: Modular design with a small footprint, easily integrating into existing feed production lines without extra space.
- Low-Noise Transmission: Adopts V-belt drive for smooth power transfer, reducing noise (≤85dB(A)) and vibration—minimizing equipment wear.
- Consistent Feeding: A dedicated feeding hopper ensures uniform material supply to rollers, preventing overload and maintaining stable capacity.
2.4 Easy Maintenance & Longevity
Wear parts (rollers, bearings) are standardized and quick to replace. The openable machine body simplifies internal cleaning, while roller surfaces are treated with wear-resistant materials—doubling service life compared to ordinary crushers.
3. Model Types & Application Scenarios
The crusher is tailored to different feed types via double-roll or three-roll designs, ensuring optimal performance for specific needs:
| Model Type | Key Advantages | Applicable Feed Types | Why It Fits |
|---|---|---|---|
| Double-Roll Crusher | Simple structure, cost-effective, easy operation | Poultry feed (chicken, duck, goose pellets) | Poultry feed requires moderate uniformity; double-rolls balance cost and performance. |
| Three-Roll Crusher | Continuous feeding, finer uniformity, higher yield | Aquatic feed (fish, shrimp pellets); chick starter feed | Aquatic creatures are sensitive to particle size; three-rolls ensure minimal powder and stable water quality. |
4. Technical Parameters
| Model No. | Roll Size (Dia.×Len) | Quick Roll Speed | Slow Roll Speed | Capacity | Power |
|---|---|---|---|---|---|
| Y112M-4 | 150×800mm | 725r/min | 475r/min | 2-4t/h | 4Kw |
| Y132S-4 | 150×1000mm | 725r/min | 475r/min | 3-6t/h | 5.5Kw |
| Y132M-4 | 150×1500mm | 725r/min | 475r/min | 5-10t/h | 7.5/11Kw |
| Y160M-4 | 200×1700mm | 725r/min | 475r/min | 8-12t/h | 11Kw |
5. Core Advantages
5.1 High & Stable Capacity
Optimized roller size and speed matching ensure constant output—from 2t/h (small workshops) to 12t/h (large factories)—supporting 24/7 continuous production.
5.2 Gentle Crushing & Low Waste
The “extrusion-tearing” method avoids over-grinding, reducing fine powder generation by 10-15% compared to hammer crushers. This lowers feed waste and improves product value.
5.3 Wide Application Range
Adjustable tooth forms and roller spacing cover 90% of feed crushing needs, from hard livestock pellets to soft aquatic feed.
5.4 Minimal Downtime
Standardized spare parts are readily available, and no professional tools are needed for replacement—cutting maintenance time by 40%.
6. Selection Suggestions
- Small Poultry Feed Factories (2-4t/h): Choose Y112M-4 (double-roll) for cost-effectiveness.
- Medium-Scale Feed Plants (5-10t/h): Opt for Y132M-4 (double-roll) to balance capacity and investment.
- Aquatic Feed Factories (3-12t/h): Select Y132S-4 (small) or Y160M-4 (large) three-roll models for precise particle control.
- High-Precision Needs (e.g., Chick Starter Feed): Pair three-roll models with fine-tooth rollers for 0.6-1.5mm particles.
