The sigma Kneader machine, also known as the sigma Mixer, is a unique and versatile mixing equipment designed to perform homogeneous kneading operations for heavier viscosity materials. It is characterized by its double Z blades that rotate in opposite directions, allowing for the achievement of uniform kneading with shear force.
This sigma kneader is widely used in various industries for mixing, kneading, and grinding operations, making it a must-have for applications such as adhesives, pharmaceutical products, polyester compounds, food products, soap, detergent, chemicals, dyes, pigments, putty, fiberglass, and confectionery items, among others.
The sigma mixer machine consists of a double U-shaped bowl welded together, with two Z-type sigma blades that rotate in opposite directions to each other. The machine is designed to achieve utmost kneading and mixing efficiency, with the clearance between the walls and the containers kept as minimal as possible. The mixer trough and blades are made of mild steel or stainless steel depending on individual requirements. The Z blade mixer is equipped with safety guards and grills, scoring high marks in terms of safety.

The sigma mixer machine achieves thorough mixing through the tangential action of two Z-shaped kneading blades that rotate in opposite directions to transfer material from one blade to another, resulting in homogeneous mixing operations. This working principle allows the machine to perform uniform kneading with shear force, ensuring consistent and thorough blending of materials.
The sigma mixer machine offers several advantages, including:
