Powerful residue processing technology adds value and sustainability

The Bruks Klöckner residue upgrader RU 14-4 is a heavy-duty machine capable of performing a wide variety of wood residue processing tasks. The RU 14-4’s outstanding features include its robust construction, high efficiency and the reliable production of wood chips.

It is ideal for use across a wide range of applications including the pallet, panelboard and furniture industries, sawmills, carpentry businesses and wood fiber-packaging manufacturing. It ensures that any end-of-life timber is not wasted, but repurposed, maximizing the profitability of an operation and also its sustainability.

The RU 14-4 upgrades waste or end-of-life timber to deliver wood chips that can be used for a range of purposes, for example, in the bioenergy market. Input material can include pallets, particleboard, hard and soft wood waste, bark, medium-density fibreboard (MDF) and oriented strand board (OSB).

Whole pallets handled with ease

The RU 14-4 has a wide-diameter hopper, which can accommodate large off-cuts, logs, and all common pallet sizes, including single-use types. It can withstand smaller-sized extraneous material due to the rotation speeds of the rotor and the geometry of the knives. This means that complete pallets, including packaging items, nails, screws and metal fittings can be shredded. In cases of excessive extraneous material, the machine will automatically stop to avoid damage.

Heavy-duty performance

Material is delivered into the unit via a powerful, hydraulically operated pusher with optimized geometry. The pusher is guided by large rollers and its action is dependent on the load entering the machine. Both the machine and its pusher floor make use of reinforced Hardox material, making it extremely durable.

The number and size of the cutting tools, as well as the screen perforations, are dimensioned according to operational requirements and the type of input material handled. The machine housing features a user-friendly design, allowing for quick and easy control, including the rotation of cutting tools, counter-knives and screens.

Designed for minimized maintenance

Maintenance costs are minimized through good design and the quality of components, including the wear-resistant steel cutting tool, which can be rotated to even wear patterns and maximize use.
