Double-Shaft Shredder GDB Series

Double-Shaft Shredder GDB Series

The GDB series double-shaft shredder is specially designed to handle waste from municipal green waste, rootstocks, untreated waste wood, straw or fruit shells of crops, etc. It can quickly shred biomass materials into small pieces. GEP Ecotech's double-shaft shredder has high output and reliable performance, widely used in biomass cogeneration power stations.


Biomass is a renewable organic material of plant and animal origin and is an important alternative fuel for electricity or heat generation. The high value of biomass and the low cost of disposal are receiving increasing attention, and there are now many power stations around the world dedicated to burning biomass.

Working Principle

The biomass shredder is driven by a motor that drives two cutter shafts that rotate the cutter and sleeve at low speed. The shearing effect is achieved by the shearing of the adjacent cutter face edges on the cutter shaft, the shearing of the cutter tip against the cylindrical surface of the sleeve and the tearing by the torque and speed difference of the cutter shaft.

GEP Ecotech offers cost effective biomass pre-shredding equipment, the GDB range of double-shaft shredders are ideal for the integrated use of biomass due to their ability to process material to a small size in a single pass, high capacity disposal, intelligent maintenance and continuous operation. the GDB double-shaft shredder blade set is optimized for the processing of lignin and cellulose and is cost effective and durable.
