Two Companies share a Common Philosophy
A good Basis for a Successfull Collaboration
Zollikofer is an international logistic and commercial business for saw by-products, used, forest and energy wood with headquarters in Bad Wurznach. Since 1966 Zollikofer has been successfully active in wood logistics and trade. With five locations for wood processing and storage all over Germany, Zollikofer has been one of the market leaders for years. ”We understand our customers as partners to whom we forward goods of the highest quality and at reasonable prices as quickly as possible. Due to our well thought-out and proven processing and logistic processes, we not only secure the quality of our raw materials, but also the complete satisfaction of our customers”, said Wilfried Zollikofer regarding the corporate philosophy and image.
Since 2013 the company uses processing technology from HAAS at two locations. The processing plant at the location Riedlings was commissioned in October 2013. So far 87 500 tons of waste wood have been processed in 2500 operating hours. The main consumer of the processed material is the chipboard industry. The processing line has been designed for a throughput of 35 t/h.
The centerpiece, a HAAS hammer mill, type HSZ-V 1600, is equipped with a ballistic chute and an easy screen change system. Due to the ballistic chute, foreign parts are separated automatically. In the past, foreign parts had to be removed manually, which was extremely time-consuming. Another advantages is that downtimes as well as wear are reduced significantly due to this system. With the help of the easy screen change system it is possible for Zollikofer to open the hammermill hydraulically and change the screen basket within a very short time. Downtimes and wear are reduced; as a result costs are minimized.
Zollikofer is supplied with unprocessed waste wood and with pre-crushed material. Feeding is carried out via two components, i.e.a feeding bunker, which loads the pre-crushed waste wood and a HAAS Double Shaft Slow Speed Shredder type TYRON 2000, which preshreds the unprocessed waste wood. The material from the feeding bunker is passed to the hammer mill via a HAAS conveyor belt. Parallel to this, the unprocessed waste wood is pre-shredded by the slow speed shredder and also passed to the hammer mill on the conveyor belt. Ferrous parts are separated by strong electrical magnets. The hammer mill is continuously and uniformly fed by means of the intelligent control system. If there is not enough material from the slow speed shredder, more material is taken from the feeding bunker. ”Thus, Zollikofer saves a medium-sized-five-digit amount per year”, calculated Hubert Achberger, the Technical Manager. Afterwards, ferrous and non-ferrous parts, which are still in after grinded material, are separated again. The material is then separated by a flat screen into different fractions and transported to a storage bunker.
Quality, partnership and reliability - these are values that determine the activities and work of HAAS.
