Double Arm Mixer

S.S.ENGINEERING  have developed   robust   SIGMA MIXER    for various operations   of  high viscosity material mixing , kneading, grinding, dispersion ,drying etc. for long term trouble free process

SIGMA MIXERS are used for  processing  Viscous to highly Viscous material in various industries viz. Adhesives, Brake lining, Chemical, Confectionery, Carbon Black, Ceramic, Dyes & Pigments, Food Products,  Fiber  Glass, Grease, Lead Storage Battery,  Magnetic Tape Coatings, Paint, Polymers Plastic, Putties, Plastic, Pharmaceuticals, Printing ink, Resin, Rubber, Soaps & Detergent etc.

CONSTRUCTION

SIGMA MIXER  consists of two counter rotating blades in a rectangular trough curved at the bottom to form two longitudinal half  cylinders and a saddle section .The blades are driven by gearing at any side end.  Container made of either Mild Steel or Stainless Steel 304 or 316 with jacket of Carbon Steel covering two side for heating or cooling application & dust free cover to get Vacuum if desired or normal cover.

 SIGMA MIXER BLADE The mixing elements (Blades) are of Sigma type Steel casted and duly finished two in number which contra rotate inward fitted at close or specified clearance with the container to give thorough and uniform mixing. There is a Gland pusher of Gun Metal Bush which ensure minimal  friction and extend the life of mixing elements (Blades) Shaft.

BLADE ACTIONThe mixing action is a combination of bulk movement, smearing, stretching, folding, dividing, and recombining as the material is pulled and squeezed against blades,saddle, and sidewalls. The blades are pitched to achieve end-to-end circulation. Rotation is usually such that material is drawn down over the saddle. Clearances are as close as 1 mm - 2 mm.

The blades are  tangential. Tangential blades are run at different speeds, with the advantages of faster mixing from constant change of relative position, greater wiped heat-transfer area per unit volume, and less riding of material above the blades.

The sigma-blade mixer is capable of starting and operating with either liquids or solids or a combination of both. The sigma blade has good mixing action ,readily discharges materials which do not stick to the blades, and is relatively easy to clean when sticky materials are being processed.

DRIVE The Drive Consists of Motor of type TEFC Or TEFC Flameproof of Specified HP.1 440 RPM, Reduction Gear Box Of Reputed Make having suitable size and ratio, Spur Gears, are also provided of adequate size and having machine cut teeth, between the front and rear blade complete with guard suitable for grease lubrication.

 STAND The complete Mixer is Mounted on Steel Fabricated stand of suitable strength to withstand the vibration and give noise free performance.

DISCHARGE (Bottom Discharge) Bottom door or valve will be used when 100 percent discharge orthorough cleaning between batches is not an essential requirement.

TILTING DISCHARGE If 100 percent discharge or thorough cleaning between batches is  essential, double-arm mixers are tilted for discharge. The tilting mechanism may be manual, motorized mechanical, or hydraulic.

STANDARD FEATURES:  Up to 150 litres,  include a manual discharge  and motorized mechanism  and above    heavy duty  hydraulic tilt mechanism  up to 100 degrees rotation forward as standard.
