As biomass-to-energy applications gain traction across Southeast Asia, efficient pretreatment of agricultural residues becomes essential. A recent inquiry from a Southeast Asian client highlights this trend. The client aims to process loose paddy straw and Napier grass, with a processing capacity of 5–10 tons per hour, maximum feed length of 3 meters, and a target discharge size around 100–200 mm, for further reduction before feeding into a biomass power plant. After initial communications, we GEP ECOTECH, came up with a double shaft shredding solution for the client.
Why Shredding Matters for Biomass
Raw straw and grass are light, entangled, and difficult to handle directly. Their low bulk density and high moisture content make transport, storage, and combustion inefficient. Shredding helps reduce volume, untangle fibers, and prepare the material for drying, fine shredding, or direct biomass cofiring. It is the first critical step in ensuring stable fuel quality and efficient biomass fuel pocessing and biomass recycling.
GD Series Double Shaft Shredder—Built for Tough Biomass
As one of the best selling biomass shredders, GEP ECOTECH's GD Series Double Shaft Shredder is ideal for loose and fibrous materials like straw and Napier grass. Operating at low speed and high torque, it effectively tears apart long, messy feedstock with high resistance to clogging and wrapping.
Key advantages include:
- Double Motors + Double Planetary Reducer Drive: With strong power, high shearing force, high shredding efficiency.
- Large Capacity Work Area Design: Can cope with different forms of bundles, different forms of loading, higher efficiency.
- Heat-Treated and High-Precision Machined Integral Cutter Box: Not easy to deform, more load-bearing capacity, smooth working conditions.
- Adaptability to Loose, Long Material: Easily handles materials up to 1.5 meters without pre-cutting.
- Anti-winding Fixed Cutter Design: Significantly reduces fiber entanglement around the shafts. This design ensures smoother operation with less downtime, especially effective for handling soft, stringy biomass like straw and grass.
- Stable, Low-Maintenance Operation: Rugged cutter design and intelligent overload protection ensure operational safety and reliability even under tough conditions.
Other Biomass Shredding Solutions Available
For customers requiring finer particle sizes around 10–50 mm, GEP ECOTECH also offers the GXB Series Biomass Fine Shredder, ideal for high-quality biomass fuel preparation. For dry, woody feedstocks, the GZP Series Biomass Chipper provides a high-speed, high-capacity chipping solution with discharge size control via built-in screens.
Whether your feedstock is straw, Napier grass, wood branches, EFB, or coconut shells, GEP ECOTECH offers tailored biomass processing systems combining conveying, shredding, and intelligent control—helping clients achieve cleaner energy goals with reliable, adaptable technology.
