It is used in food industry, pharmaceutical industry, soap industry and chemical industry at large. These Sigma Mixers has a vigorous structure and are produced using best material to cause to be utmost client approval.

SIGMA KNEADERS


INTRODUCTION
RIDDHI SIGMA KNEADER MIXERS are excellent for kneading and mixing of highly viscous materials like dough, putty, rubber solutions, adhesives, polymers etc. The mixing action is a combination of smearing, stretching, folding, dividing and recombining as the material is processed between the sigma blades and the container walls. Jacket arrangement is provided for heating or cooling application. In higher capacity models the container can be tilted by a hydraulic cylinder
( optional at extra cost ) to ensure complete discharge of mass.
RIDDHI SIGMA KNEADER MIXERS are engineered specifically for kneading, mixing, and homogenizing wet, pasty, and highly viscous products. The mixer consists of two counter-rotating tangential rotors in specially shaped trough, curved at the bottom to form two longitudinal half cylinders with sufficient overboard volume.
The blades rotate at different speeds in opposite directions causing the product to be transferred from blade to blade and from end to end, resulting in a figure eight pattern. The main trough is of fully welded construction. The blades have taper surface and key fitted to different helical gears working on anti-friction bearings. They are driven by gear on both sides in heavy duty models and pitched to achieve end to end longitudinal movement of the material resulting in thorough kneading action. The shaft sealing is achieved by bearing housing / stuffing box arrangement with seals impregnated gland packing.
Options:
• Mechanical or hydraulic drive system.
• Jacketed mixing troughs or heating and cooling.
• Designed for pressure, vacuum, or inert gas operation.
• Remote operator control.
• Specialized die heads / special extrusion spouts.
• Automated operation of cover via hydraulic piston.
• Cored blades of various designs

CONSTRUCTION & WORKING PRINCIPLE :
RIDDHI Sigma Kneader Mixer comprises of a double “U” Shaped Container with Shell 6mm Thick and Side Walls 20mm M.S. with 6mm S.S. 316 cladded / welded and machined together inside which rotate two “Z” Shaped Sigma Blades in opposite directions at 2 different RPM i.e. 36/48 RPM. The clearance between the blades and the walls of the container are kept to the minimum to ensure maximum efficiency in the kneading and mixing action. The shafts of the Sigma Blades are fitted in bearing blocks which are each provided with roller bearing, steel glands, Teflon/rubber seals for smooth and leak less running. Lubricating points are provided for continuous lubrication of the shafts. A hinged type cover with locking bolts is provided for charging the kneader. The Kneader is mounted on a sturdy base frame fabricated out of ISMC section and free from vibrations. The machine is
provided with a normal S.S. 304 Jacket arrangement for heating or cooling as required.
