Sigma Kneader

Sigma mixer consist of two sigma shaped mixing blades positioned within in a ‘w’ shaped mixing vessel. The clearance between the blades and the vessel walls is low (~2 mm). The low clearances produces high shear and particle size reduction. Material is loaded into the mixer from the top of the vessel and discharged by tilting the container assembly. Sigma mixers are best suited for mixing, kneading of highly viscous mass, sticky and dough like products. Mixing of pastes, rubber, and heavy plastic masses. Applications in Food, Rubber, Pharmaceutical and Chemical industries. Dry powder to wet phase mixing
