SIGMA MIXING MACHINE is a heavy-duty mixer specially designed to produce uniform mixing, blending & kneading of highly viscous, paste & dough type materials. Sigma mixer is used for kneading of putty, epoxy, paints, pigments, adhesives, gums, battery pastes, welding electrode flux, catalysts paste, plastic compounds, rubber compounds, papad, chocolate, bubble gum, etc.
The tangential action of mixing and kneading is thoroughly obtained by two ‘Z’ shaped kneading blades, which rotates very accurately at different speed towards each other causing the product to be transferred from one blade to the other. The mixing action is a combination of bulk movement, stretching, folding, dividing, and recombining of the material. The shearing & tearing action of the material against blades and the side walls causes size reduction of the solids.
