Wood or bio-gasification installations as well as pellet heating installations for private use are getting more and more popular.
For many years now, HAAS GmbH has been producing chipping installations for the fabrication of quality chips out of waste wood.
Another focus lies on the development of a concept to achieve "clean fractions" out of the waste wood treated in complete installations. These fractions can then be further processed in corresponding installations.
During the past years a special challenge has been the achievement of a higher "purity level" as well as an efficient fine grinding of the wood in order to be able to use a highest percentage of the waste wood residuals.
As the importance of the pellet industry is steadily growing, a new necessity was the integration of a crusher for chips with high moisture content.
After this process the fine chips are transferred to the following band dryer. Thus the drying time (and so also the time the chips pass the installation) is minimized.
The processing can start either with a stationary drum chipper (for the crushing of waste wood residuals from sawmills) or with a mobile drum chipper installation used in forestry. Then HAAS proposes a refiner for the further processing of the wood chips.
The refiner type HSZ-R 500 x 1800 is optionally equipped with feeding vibrating conveyor guaranteeing a regular infeed to the refiner.
Another option is a FE-separation before the machine in order to separate FE-parts. Furthermore it is possible to include a heavy particle separator for the separation of heavy particles as mineral material (stones etc.).
An important advantage of the refiner (fine hammermill) is the user-friendly operation and maintenance. The machine sides including screen and grinding segments are to be opened hydraulically assuring a good access to the interior of the machine.
The screen and grinding segments are screwed to the machine housing and are easily to be dismantled. As the machine housing can be completely opened, even the tool change is easily to be effected.
