Mikrons manufactures twin basin kneading machine. The product is a sigma kneader with two horizontally arranged kneading blades that are deeply geared into one another and strip themselves reciprocally. The kneading blades run to a ratio 1:2. The blade sides approach and withdraw alternately because of their different speed. This causes high pressure tensile and shearing rates and therefore heavy friction in the kneading medium, which creates excellent dispersing and homogeneity. The shape of the kneading blades enables a steady flow of material from the side walls of the kneading trough to the middle of the kneading trough.
