Sigma Mixer Machine

Sigma Mixer MachineFor consistent mixing of semi-solid materials, a z-blade mixer is included in the sigma mixer machine  (sigma mixer Kneader). A U-shaped bowl with two “Z”-shaped blades that revolve in opposite directions to properly mix the material makes up the mixer. machine with a motor and gearbox capacity determined by the specifications of the process and product. Jacket arrangements are included with the equipment for heating and cooling purposes. Sigma Mixer Machine are what we make, and their capacities range from 5 kg to 5000 kg.

The Sigma Mixer Machine finds extensive application in blending polyester putty, rubber solution, sauce, biscuit dough, polymers, and more. One of India’s top producers of sigma mixers is Adinath. Our selection includes 10 liter Small Sigma Mixers and 3000 liter Heavy Duty Sigma Mixers.

Process Operation of Sigma Mixer Machine

In Sigma mixer tangential action of mixing and kneading obtained by ‘Z’ type (SIGMA) shaped kneading blades, which rotates very accurately at different speed towards each other causing product to be transferred from one end to another end. Discharge of the finished product is achieved by tilting the container or through the valves at the bottom or by means of an extrusion screw beside the container.

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. After the time period required for sterilizing the batch has elapsed, the heating circuit shuts of the pneumatics damper (exhaust) opens and cooling operation commences.

In the tangential design, the blades rotate in the trough meeting tangentially. The front blade generally rotates faster than the rear blade usually in the ratio of 3:2. Tangential blades are generally used for material of higher viscosities such as adhesives, rubber compounds, flush colors, dyes, and pigments.

In the overlapping design, the blades overlap above the saddle of the container. Due to the overlapping action, it is necessary that the relative position of the two blades is unchanged, and as a result, both the blades rotate at the same speed. Materials that flow freely or creep down into the blades are mixed using the overlapping blade action. This design offers a faster interchange of material from one blade compartment of the mixer to the other. Overlapping blade action is used for materials of lighter viscosities such as carbon pastes, clay coating, creams, and ointments. The overlapping blade produces a lower kneading and shearing compared to the tangential blade action.
