“ Woodchipping quality and low fines content are the most important parameters for ligneous biomass ,” according to equipment supplier , Jenz . For this reason , the company has now developed the new H1 drum for very coarse woodchippings with low fines content .
The new HEM 821 Z power takeoff shaft chipper was one of the first machines fitted with the new drum by French importer Noremat .
Christophe Mazoyer , product manager for Jenz dealer , Noremat , presented the machine during the Salon Bois Energie specialist trade fair in Nancy , France , and was extremely satisfied .
“ A super machine , which doesn ’ t just stand out thanks to innovative solutions in the drivetrain , but also because of the considerably-improved woodchipping quality ,” he said . These results were also confirmed by FIBOIS Ardèche Drôme , a consortium of companies working in the timber industry in the Ardèche and Drôme regions . In an independent trial , FIBOIS investigated the woodchipping quality from the various exhibitors during the trade fair . The results

obtained from the HEM 821 Z fitted with its new H1 chipper drum were reportedly excellent . The woodchipping quality was obvious . The development of the new chipper drum with the catchy name of H1 played a particularly large role in improving the woodchipping quality .
“ Two decisive specifications are hidden in this name ,” said Uwe Hempen-Hermeier , Managing

The new drum has been implemented as a single-cut drum , which enables optimised outflow of the woodchippings after being cut . Removable wedges ensure simple and rapid conversion from 20-30 mm pre-grip , which is extremely important for the production of coarse woodchippings , and also means that the particle size distribution required by smaller plants does not present any problems .
Thanks to the flexible and rapid conversion of the pregrip and the screen baskets
Optimised flow post-cut is a neat feature of the 821 Z with H1 drum
