This Sigma Kneader machine comprises of a double ‘U’ shaped container welded and machined together inside which rotates two ‘Z’ shaped sigma blades in opposite directions. The clearances between the walls and the container are kept to a minimum to ensure maximum efficiency in kneading and mixing. The shafts of the sigma blades are fitted in bearing blocks which are each provided with roller bearings, steel glands/Teflon rubber seals for smooth and leakless operations. The kneader is mounted on a sturdy base frame fabricated out of ISMC sections and are free from vibrations. For cooling and heating jackets are provided.
These types of machines are available in M.S. and S.S. construction. The kneader can be tilted by means of a mechanical system or manually and for bigger models beyond 250 Kgs we provided hydraulic tilting.
Hydraulic tilting system is provided with complete power pack, electric motor, pressure valves, pipes, fittings, cylinders and hoses which makes the tilting mechanism quick, easy and simple to operate.
The sigma kneader is a mixer designed to process highly viscous materials. It consists of two blades that rotate towards each other at the same or different speed inside a container. The twin screw basin kneading machine with two horizontally arranged kneading blades, which are deeply geared into one another and strip themselves reciprocally. Each blade moves the material in opposite direction thereby providing excellent cross mixing of all raw materials. The blades pass the trough walls and each other at close clearances resulting in good mixing. The close clearance produces a shearing and tearing action that is beneficial to the size reduction of solids. Selection of appropriate blade shape and speeds result in excellent mixing.
