Binderholz GmbH, one of Europe’s leading wood processing companies, recently decided to purchase the VAZ 80, a compact and sturdy single-shaft shredder, for its facility in Jenbach, Austria. Presented to industry specialists for the first time earlier this year at Ligna 2017, Binderholz ordered one right there and then.
Founded over 60 years ago as a small sawmill, Binderholz has emerged as one of the leading solid wood processing companies in Europe. The family-owned company’s solid wood products include lumber, profiled timber, single-ply, and multi-ply edge-glued solid wood panels, glulam beams and cross-laminated timber (CLT). There are about 2 530 employees at the company’s twelve manufacturing facilities located in Austria, Finland, and Germany.
No waste principle
Binderholz has a sustainable and efficient production system based on the no-waste principle, all waste wood is completely recycled into products or energy. The applications include wood pellets, green electricity, multipurpose panels, moulded pallet blocks, and moulded wood pallets. Binderholz uses a VAZ 80 single-shaft shredder from Vecoplan to process wood leftovers at its facility in Jenbach, Tyrol (Austria).
Vecoplan AG, a machine manufacturer based in Bad Marienberg, Westerwald, Germany presented its VAZ series to industry specialists at the international trade fair Ligna 2017 in Hanover earlier this year. Attendees from Binderholz were impressed with what they saw, so much so that a purchase order was struck on the spot.
Low-dust, quiet and powerful
Single-shaft shredders are universal machines, which in most applications can manage without additional feeding systems. With our VAZ series, users can feed in the collected materials directly without a feeding system, explained Helmut Bammer, Vecoplan’s Area Sales Manager for Austria, who is responsible for Binderholz.
According to Bammer, the VAZ series with its energy-efficient drive technology was developed for reliable and cost-efficient processing of wood leftovers. A hydraulic slide feeds material in the hopper quickly and easily into the shredding mechanism.
Since the rotor turns particularly slowly, it makes little noise or dust during vertical feeding. The VAZ 80 has a rotor diameter of 250 millimetres and a rotor width of 800 millimetres.
Low operating costs
A special feature of these compact units is their patented ESC drive. With a motor capacity from 11 to 37 kW, the asynchronous motor with its powerful frequency converter is energy-efficient, inexpensive and economical in operation.
According to Vecoplan, up to 25 percent less energy is needed compared to conventional shredders in the same capacity class. The belt drive features sophisticated slippage control along with contaminant material detection – and fast reversing and restarting make the ESC drive very dynamic.
The cutting unit consists of a profiled rotor with easy-to-change counter-knives that can be used on both sides. The rotor is mounted inside a solid steel housing.
The machine has been operating in three shifts since its successful start-up at Binderholz in Jenbach. Fitted with a 20 mm screen, it efficiently shreds over more 500 kg of spruce offcuts per hour and Binderholz is highly satisfied with its performance, ended Helmut Bammer.
