Industrial mixers manufacturer Winkworth is reporting success with two new hydraulic drive systems – one for a 450 litre twin-blade waste and recycling mixer/extruder, the other for a hazardous fluid mixer/incorporator.
 Winkworth sales director Tim Simpson explains that the first unit was for a tough process and that its machine needed increased power and efficiency to improve on earlier plant's productivity rates.
He selected Branch Hydraulic Systems for the project, not least because it was able to provide 66kW in the envelope available, via three 22kW motors.
Branch specified a Comer planetary gearbox from its sister division, Tractec, integrated with a hydraulic power unit based on Parker load-sensed, constant horsepower piston pumps and Sauer Danfoss proportional valves, for speed and torque control.
Meanwhile, the second drive was for a double Z blade mixer/incorporator, designed for hazardous fluids and powders. Being a more compact mixer, Branch delivered an 11kW power supply driving a single Comer foot-mounted planetary gearbox.
Again, to optimise performance, the hydraulic power unit has a Parker load-sensed, constant horsepower piston pump and, in this case, a Duplomatic proportional valve.
Commenting on the choice of Branch, Simpson says: "We wanted to work with a company that specialised in hydraulics, one that would be both responsive and helpful whilst ultimately providing a cost effective and efficient result."
