Sigma mixers consists of two mixing blades placed in a 'w' shaped horizontal trough. The rotation of the blades is either tangential to each other or the blades overlap within the trough. The blades are so designed that the resulting output is homogeneous mixing. The blade profile of the sigma blade is such that the viscous mass of material is sheared, compressed, kneaded and folded by the action of the blades against the trough of the mixer. Tangential blade is used for material of higher viscosities such as adhesives, dyes and pigments. Capacity Range from 100 Liters to 500 Liters. MOC : SS304 & SS316L
