Description
The caterpillar pelletizer is essentially a dry-extrusion pelletizer; it is so named because the material is continuously extruded through the die holes as long, cylindrical strands that closely resemble caterpillars. The main unit consists of a feed hopper, a forced feeding mechanism, a vertical flat die plate, a pressure roller assembly, a heavy-duty gearbox, a main frame, an external cutting blade, and an electrical control system. It features a screw-free melting design and is a purely physical cold extrusion machine that does not require heating or melting the material.
















Key Features
Key Product Features (Differences from Screw Granulation)
- Pure dry extrusion process; no heating or melting required, resulting in extremely low operating costs
- Optimized for loose, fluffy materials; forced feeding prevents material from hanging in the air or arching
- Compact pellets that are resistant to breakage
- Modular drive structure ensures low failure rates and strong resistance to impurities
- Simple maintenance; cost-effective replacement parts
- Dual-purpose machine capable of both pre-compression and baling, as well as direct production of finished fuel pellets
- Compact footprint and simple installation
