Alpha process engineers sigma mixers. Sigma mixers are suited for medium-to-high viscosity solid-liquid media, where the other machines like planetary mixer, helical-blade mixer, etc, prove inappropriate or inadequate sigma mixers are relatively power-intensive, slow speed mixers. Even tough materials experience stretching, folding, spreading, dividing and recombining in the course of the mixing and kneading operation. These mixers have a twin-blade configuration, which rotate in opposing directions, either tangentially or with a certain amount of overlap. A variety of blade configurations are offered to suit applications like the conventional sigma z, double naben, dispersion, multi-wiping overlapping, etc. Careful attention has been paid in the design to eliminate/minimize leakage and can boast of being one of the least downtime machines [amongst equals] in the field today. Above a certain capacity, depending on drive power required, alpen sigma mixers features double-ended drive transmission through hardened gears. Jacketed versions are offered too. The sigma mixers are available in different models with batch capacity of 50 to 1,000 litres per batch.
