The heavy shredders are equipment manufactured in Brazil with technology from French company FIVES.
It is a sugarcane preparation system that requires no knives set before it. The main features are high preparation index up to 92 % with long fibers, which facilitates the operation of the mill and the diffuser, and a low specific energy consumption, when compared to conventional systems. This heavy shredder consists of a drum feeder followed by the rotor and, depending on the proportion of whole sugarcane and sugar cane stalks being processed, one or two leveler drum driven by electric motors of low power.
The equipment requires few maintenance and a simplified removal of hammers.
