The Sigma Mixer by Apmates Engineering is designed for high-efficiency mixing of viscous pastes and dough-like materials. Commonly used in industries such as rubber, adhesives, chemicals, pharmaceuticals, and food processing, this mixer is ideal for blending, kneading, and homogenizing highly dense materials. The mixer features two counter-rotating sigma-shaped blades that operate within a specially designed mixing trough. These blades generate shear forces that help in the uniform mixing of ingredients, even under heavy loads.
