Z Blade Sigma Mixer

Experience unparalleled mixing, kneading, and dispersion with Winkworth’s world leading Z blade sigma mixer, boasting the highest shear forces thanks to our proven Z blade design. Crafted entirely from stainless steel, with an option for 316 grade construction for product contact parts, tailored finishes such as polished, bead blasted, or mill finish are available. For high wear applications, choose from special hardened steels and finishes, complemented by replaceable wear tip blades and liners for durability.

Operating at low speeds to maximise energy application, our mixer features an ω-shaped trough, ensuring tight blade clearance and efficient mixing sweep. The kneading action achieves thorough homogenization of products, delivering superior results across various industries including food, chemicals, pharmaceuticals, ceramics, metals, rubbers, and plastics.
