The W70 Windsifter is designed for cleaning light impurities, such as plastic, out of screened compost and biomass materials. The W70 Windsifter has a dedicated infeed hopper with an integrated metering roller, allowing operation independently of a trommel screen. The W70 can be loaded via a wheel loader, or used in tandem with a trommel or star screen for superior material separation.
The machine is fed using a wide, flat belt conveyor at the bottom of the hopper, into a chamber (via a metering bar) where a strong air stream aerates the material. Light material (such as plastic) is pulled out of the material stream, and sorted material is then dropped onto two discharge conveyors. The first conveyor has a stone separator to remove light weight stones from the material and the final discharge conveyor has a magnetic head pulley to remove any ferrous materials from the compost or biomass. The waste material is collected into a separate waste collection bin.
The W70 is powered by a fuel-efficient (108 hp) 81kW JCB diesel engine, and is easily moved with its built in pintle hitch system. The highly efficient W70 system is capable of throughput rates of up to 105 yd³ per hour.

Dosing Roller The Dosing Roller ensures an even feed of material into the machine.
Destoner Belt This feature is a secondary conveyor that can be added to any screening machine. The destoner belt pivots from horizontal to vertical allowing stones to roll backwards while processed stock continues to move forward on the conveyor belt.
Maintenance Friendly The machine is a maintenance-friendly design, and all functions are hydraulically powered.
Impressive Throughput Rates The W 70 Windsifter impresses with a high, continuously adjustable cleaning level at throughput rates of up to 105 yd³ (80 m³) per hour.
Infeed Hopper with Metering The infeed hopper is equipped with the proven positive-fitting drive system from the Terra Select trommel screens. In addition, a metering roller ensures an even infeed of material into the machine.
Added Features Additional features include a hopper with metering roller, stone separation and magnet roller.
Magnetic Roller The magnetic roller is a magnetized conveyor puller used to remove metal from processed material.
