Sigma Mixer, Size : 8 ft x 4 ft

The sigma blade mixer is commonly used for mixing and kneading high viscous materials
usually in combination with a solid to another liquid material in variable proportions. It
belongs to the class of double arm kneader mixers. The commonly used blade types are the
sigma blade, masticator blade, shredder blade etc. The rotation of the blades could either
be tangential to each other or the blades could overlap within the trough. The blades rotate
toward each other at the same or differential speeds. The blades pass the container walls
and each other at close clearances, normally within 2 - 3 mm resulting in uniform and
homogenous mixing. The close clearances produce very high shearing action thereby
promoting homogeneous mixing which could be achieved within several minutes to hours
depending on the type of materials used.
