SHREDDERS & GRINDERS
Considerably simplified maintenance and feed-in, optimised draw-in behaviour and extremely high throughput - these are the keywords JENZ is using to advertise its new BA 915 D biomass processor. The machine has been fitted with many innovative detailed solutions, and was presented to the public at the IFAT for the first time. In comparison, woodchippings have proven themselves as an absolutely competitive energy source over the years. However, reducing oil prizes and the mild winter have caused a difficult market situation at the moment.
Low-quality garden and park waste is therefore used for composting more often than not, and JENZ has now developed the BA 915 D for precisely this purpose. The new shredder has not only been designed for composting, it can be optimally used for substrate preparation. In a similar manner to composting, input material must be fragmentised for biogas facilities so that it can be stirred more
easily and promote gas formation. Irrespective of which application, any machine used must be extremely high-powered and, at the same time, exceptionally mobile. These were the core requirements on the new BA 915 D. In detail this means that there is an overall weight of less than 19 t in the full version with metal separation and an overall vehicle length of less than 18.75 m. This
means that the BA 915 D can be towed by a 3-axis HGV which can still carry a wheeled loader at the same time. Apart from this, any type of special permit or certificate of exemption is avoided in the ideal case. In order to implement quicker coupling and uncoupling processes, the BA 915 D is fitted with a hydraulic support winch and is ready for transport within the shortest-possible time.

In addition to mobility, the JENZ designers paid special attention to the machine’s userfriendliness. The low belt hopper infeed height of only 2 m makes feed-in easier and reduces the duration of the wheeled loader lifting process, which is directly reflected in a lower energy input and quicker loading cycles. The free loading length of 4.40 m, which can optionally be extended
