Sigma Blade Mixer or Sigma Kneader is unique mixer machine perform homogeneous kneading operation for heavier viscosity materials. Double Z blades design is the exclusive feature of machine that rotate in opposite directions. Sigma Blade Kneader is advanced mixer uses to achieve uniform kneading with shear force. Sigma Mixer considered must have for bunch of operations in which mixing, kneading and grinding to name a few. It is uses for mixing wide array of products including adhesives, pharmaceutical products, polyester compounds, food products, soap, detergent, chemicals, dyes, pigments, pigments, putty, fiber glass and confectionary items to name a few.
Consists of a double U shape bowl welded together. There are two Z type sigma blades that rotate in opposite directions to each other. In order to obtain utmost kneading and mixing efficiency, clearance between the walls and the containers are kept as less as possible. Mixer trough and blades are made of mild steel, stainless steel of CF8 or CF8M as per individual requirements. Z blade mixer scores 10 on 10 in terms of safety as equipped with safety guards and grills.
Tangential action of mixing is thoroughly obtained by two ‘Z’ shaped kneading blades, which rotates in opposite direction to each other in order to transfer material one blade to another resulting which homogenous mixing operation performs.
Mixing action is combination of movement, elongating, folding, dividing, and recombining of the dough. Shearing & tearing action of material through blades and the shell causes size reduction of the solid dough. Once 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.
