SDZ Series Compound Fertilizer Granulator - No Drying Required, Energy Efficient, High Granulation Rate
The SDZ series roller extrusion granulator is a high-performance dry granulation machine designed for one-step forming at room temperature. It is widely recognized for its energy-saving design, reliable operation, and broad material adaptability.
This granulator is suitable for granulating various types of raw materials with different concentrations, including but not limited to:
- Compound & blended fertilizers
- Pharmaceutical ingredients & feed additives
- Chemical powders, rare earth compounds, metallurgical auxiliaries
- Coal fines, biological agents, and environmental protection materials
| No drying required | Granulation is completed at room temperature in a single pass, eliminating the need for drying equipment and reducing energy costs. |
| Simplified production process | Raw materials are directly formed into granules, reducing additive consumption and simplifying overall operation. |
| Durable roller design | Rollers are made of anti-corrosion, wear-resistant, and impact-resistant metal, ensuring long-term stable operation and higher output. |
| User-friendly operation | Features good sealing, low noise level, stable performance, and easy maintenance. |
The roller extrusion granulator is driven by an electric motor. Power is transmitted through a belt pulley and reducer to two counter-rotating rollers.
Raw materials enter through the feeding port and are squeezed between the two rollers under high pressure. The extruded materials form dense sheets or strips, which then break into granules after demolding. These granules automatically fall into the crushing and shaping chamber located at the bottom of the machine. After being crushed and shaped, the granules are sieved to separate standard-sized particles, which are finally discharged through the discharge chute.
