Save cash money with the new HAAS hammermill
In 1974 Jan Janssen started a transport and contractor business (J.A.M. Janssen) in the garden of his Gennep home. Initially on his own, but gradually building the business up, until it didn’t fit in his back garden anymore. This then forced him to leave the neighbourhood and relocate to nearby Heijen. Since then there have been a couple of business moves but AVG Heijen still remains.
The trade in sand and gravel brought AVG in contact with German concrete mixing plants and slowly but surely a plan was developed to build their own mixing plant. This reached fruition in 1985, thanks to much building work in Noord-Limburg, and the fact that AVG had taken over its own sand and gravel exploitation. Since 1989 there has been a permanent stone crusher in Heijen. This is used to work not only production waste from the concrete plant, but also building and demolition rubble. A second concrete mixing plant was built in Duisburg-Rheinhausen in 1999. Meanwhile the crushing capacity was increased thanks to two mobile crushers. The granulate obtained as production effluent is used, as much as possible, as a gravel substitute in our own plants.
In the middle of 2015 AVG Baustoffe in Goch invested in a new stationary HAAS waste wood recycling plant with a capacity of 30 t/h. This plant processes waste wood all grades into biomass. AVG supplies this biomass to several customers, which fuel their biomasspower plants with it.
After pre-shredding the waste wood into an edge length of about 300 mm with the stationary
slow-speed-twin-shaft shredder HAAS TYRON 1500, ferrous parts are being separated from the pre-shredded material with an electric overband magnet. This is followed by a hammermill, HAAS Type HSZ-V 1300, which grinds the pre-shredded wood to an edge length of 80 mm.
AVG’s hammermill is equipped with one of the latest innovations from HAAS, the ballistic chute. In the past foreign bodies, which can get into the hammermill along with the material, had to be removed manually in a very time-consuming manner. Time is money, the HAAS constructors thought and got to work. The result: foreign bodies are now being separated automatically by the newly developed ballistic chute.
Finally the wood chips are separated from ferrous and non-ferrous parts by an Eddy Current Separator with an integrated magnetic drum. The clean end product is transported into a storage bunker, where it remains until loading. This HAAS plant produces a yearly amount of 50.000 t clean biomass.
“Our company always stands for highest standards in competence, quality and accurateness. With HAAS we found a supplier and partner who also lives these attributes.“ confirms Ramon Janssen.
