Oilseed Crushing Machine – Key Equipment for Efficient Oil Extraction
KMEC’s oilseed crushing machines (toothed roll crusher, glossy roll crusher, and hammer mill) have been carefully designed to pre-process oilseeds into optimally sized flakes, increasing oil yields by 10-15%, while improving the efficiency of flaker presses. Our crushers are widely used in oil mills around the world for soybeans, palm kernel, peanuts, sunflower and rapeseed.
Why Crushing Oilseeds is Important
Crushing breaks the raw material into smaller particles, increasing the surface area for better moisture/temperature control during the cooking process. This step is critical for the following:
- Higher oil yields (less residual oil in the cake)
- Uniform flake thickness for consistent pressing
- Reduced energy consumption in downstream processes
Types and Applications of Oilseed Crushing Machines
1. Toothed Roll Crusher
Best for: Large oilseeds (palm kernel, copra) and oil cakes.
How it works: Polygonal sawtooth rolls crush materials via cutting and shearing action.
Advantages:
- Low powder generation (<5%)
- Adjustable roll gap (0.5–10 mm) for precise particle control
- 30% quieter than hammer mills
| Model | Capacity(t/d) | Power(kw) | Roller specification(mm) | Weight(kg) |
|---|---|---|---|---|
| KMRCФ250×800 | 70-100 | 7.5*2 | 250*800 | 3000 |
| KMRCФ250×1000 | 150-200 | 11*2 | 250×1000 | 3500 |
| KMRCФ250×1250 | 250-300 | 15*2 | 250×1250 | 5500 |
| KMRCФ300×1000 | 200-250 | 11*2 | 300×1000 | 5500 |
| KMRCФ300×1250 | 300-350 | 18.5*2 | 300×1250 | 6000 |
| KMRCФ400×1250 | 350-400 | 18.5*2 | 400×1250 | 7000 |
2. Glossy Roll Crusher
Best for: Low-moisture seeds (soybean, peanut, tea seed).
Types: Single-roll (pre-crushing) and double-roll (fine crushing)
Advantages:
- Smooth rolling surface prevents oil leakage
- Low-temperature crushing preserves protein quality
3. Hammer Mill Crusher
Best for: High-capacity processing of brittle materials (sunflower, rapeseed).
How it works: High-speed rotating hammers (1,500–3,000 RPM) pulverize materials.
Upgraded Features:
- Low-noise design (≤75 dB with soundproof casing)
- Screen mesh customization (2–10 mm)
- Anti-vibration base for stability
