Sigma Mixers (Kneader) is modern heavy duty mixer specially designed to produce uniform mixing and kneading heavier viscosity materials. It is suitable for many applications such as different kinds of doughs, stiff pastes, adhesives, polyester compounds, flush colours, brake lining compounds, resigns, soap, PVC coatings, rubber compounds, food dough, etc. 
Operation
Loading of material is done through top of mixer on opening the lid or through the feeding mouth / hopper. On starting the machine, the tangential action of mixing and kneading is thoroughly obtained by ‘Z’ shaped kneading blades, which rotates very accurately at different speed towards each other causing product to be transferred from blade to blade. Discharge of the mixed product is achieved by tilting the container or through the valves at the bottom or by means of an extrusion screw below the container if provided.
