Drum Chipper

The Drum Chipper is a robust type of Biomass Shredder featuring a heavy rotating drum equipped with sharp knives. It efficiently processes a wide range of woody and fibrous biomass, including: Logs, branches, stumps, pallets, shrubs, EFB (Empty Fruit Bunches), coconut shells, paddy straw, corn stalks, and sugarcane bagasse, etc. The machine outputs uniform-sized chips or shreds critical for biofuel production. Its primary application is supplying prepared feedstock to Biomass Power Plants, ensuring optimal combustion efficiency. Drum Chippers are indispensable in biomass preprocessing chains, enabling sustainable energy generation from diverse raw materials.

Overview

The Drum Chipper operates on a robust mechanical principle: a high-powered motor drives a horizontally mounted steel drum equipped with sharp knives at high rotational speed. As raw materials are fed onto the integrated chain plate conveyor, the rotating drum slices them into thin, uniform chips or shreds.

This machine demonstrates significant versatility in processing diverse materials, effectively handling woody biomass (logs, branches, bamboo, wood scraps, pallets, MDF/HDF fiberboard) and key agricultural residues like EFB (Empty Fruit Bunches), coconut shells, and paddy straw. However, it exhibits lower tolerance for hard contaminants such as metal or stone, necessitating pre-separation to minimize equipment wear.

Key advantages include high processing efficiency, adjustable operational parameters for material-specific optimization, consistent output sizing crucial for downstream processes, and a horizontal design with chain conveyor that excels at feeding heavy or lengthy materials like whole logs.

Proven in industrial settings, Drum Chippers serve as essential Biomass Shredders across multiple applications. Primary use cases include preparing uniform feedstock for Biomass Power Plants, generating fuel chips for combustion or briquetting, supplying raw material for pulp production, shredding bulky waste for composting, and processing recycled wood.

GEP ECOTECH enhances this core functionality by offering comprehensive support equipment—including shredders, magnetic separators, conveyors, and screens—to build complete, customized material processing lines tailored to specific throughput and purity requirements.
