This Winkworth ZX500-6 is a used mixer and blender — sometimes referred to as a Z-blade mixer or sigma mixer — designed for the intensive mixing and blending of high-viscosity materials. Winkworth is a long-established British manufacturer specialising in heavy-duty mixing equipment, serving industries including food processing, pharmaceuticals, chemicals, and materials science.
The machine is built around a stainless steel 304 mixing chamber measuring approximately 1,090 mm in length by 956 mm in width by 735 mm in depth. It offers a working capacity of approximately 500 litres and a total chamber capacity of 778 litres, with the effective working volume depending on the nature of the product being processed. The chamber is fitted with a domed hood or lid rated for vacuum operation, making the unit suitable for processes that require mixing under reduced pressure.
Mixing action is provided by two Z-shaped blades, each driven by its own dedicated 30 kW motor and gearbox, giving a combined installed drive power of 60 kW for the mixing function. Discharge is handled by a stainless steel screw extruder driven by a separate 22 kW motor and gearbox, allowing processed material to be extruded directly from the chamber. The exterior jacket is also constructed from stainless steel 304, consistent with the chamber, and is suitable for temperature-control applications via a heating or cooling medium.
The unit includes a control panel and is offered in used condition from a location in Spain.
