Sigma Mixer is a twin basin kneading machine with two horizontally arranged kneading blades, which are deeply geared into one another and strip themselves reciprocally. The kneading blades run to a ratio 1:1.2 Because of their different speed, the blade sides approach and withdraw alternately. 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. Bharat Process Equipment (BPE) offers wide range of capacities from 5 liters to 20000 liters in all material grades.
