Double arm mixers, z blade mixers, sigma blade mixers or kneader mixers as they are sometimes known, are often used for production of viscous products including foods, resins, adhesives and plastics. Double arm mixers tend to consist of two counterotating blades within a rectangular trough that is curved at the bottom to form two longitudinal half cylinders and a saddle section. These mixers can be constructed from mild or stainless steel and can have jackets fitted if heating or cooling of the product is required. There are also a number of different types of blades that can be fitted depending on the type of application, the most common are sigma blades and z blades. Discharge of the product can be accomplished by tilting using a hydraulic system, a bottom value can be fitted or using an extrusion screw to discharge the product in a form or shape.

Manufacturers of used double arm mixers include Baker Perkins, Morton Mixers, Day, Werner and Pfleiderer, Winkworth and many more.
