Sigma Mixer.
Sigma Mixer
The universal mixing and kneading
machine consists of two counter-rotating blades in a rectangular trough
curved at bottom to form two longitudinal half cylinders and a saddle
section. The blades are driven by gearing at either or both ends. The
mixing action is a combination of bulk movement, smearing, stretching,
folding, dividing and recombining as the material is pulled and squeezed
against blades, saddle and sidewalls. The blades are pitched to achieve
end-to-end circulation. Rotation is usually such that material is drawn
down over the saddle. The blades are tangential and run at different
speeds, with the advantages of faster mixing from constant change of
relative position. The blade design most widely used is the sigma blade.
The sigma blade mixer is capable of starting and operating with either
liquids or solids or a combination of both. The sigma blade has good
mixing action, readily discharges materials that do not stick to the
blades, and is relatively easy to clean when sticky material are being
processed. The drive is given through an electric motor coupled to a
reduction gearbox. The whole assembly is fitted on rigid MS structure.
The tilting mechanism is provided for discharge of product.
