Z Blade Sigma Mixer

Z Blade Sigma Mixer is uses for uniform mixing of semi solid materials. Machine consist of U trough bowl with two ‘Z’ shape blades each rotates in opposite direction for proper mixing of material. Machine equipped with suitable capacity motor & gearbox decided as per characteristics of the product & process. Equipment is provided with Jacket arrangement for heating or cooling applications. We manufacture Sigma Mixer Kneader in capacity ranging from 5 kgs. up to 5000 kgs.

Z Blade Sigma Mixer is widely uses for mixing glass putty, plasticizer solution, biscuit dough, sauce, polymers etc.

Working Principle of Z blade Sigma Mixer

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 pneumatic 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 viscosity
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 viscosity
such as carbon pastes, clay coating, creams, and ointments. The overlapping blade produces a lower kneading and shearing compared to the
tangential blade action.
