Vilas Engineering represents a business enterprise with strong commitment, foresight, technical expertise and on-time delivery. Our promoters have spent more than 3 decades in the pharmaceutical industry, which had helped Vilas Engineering carve an edge in this competitive pharma / biotech industry. We have successfully manufactured and supplied Sigma Mixers for various pharmaceutical companies.

SIGMA MIXERS
VILAS' Sigma Mixer is used for mixing highly viscous materials in various industries viz. Adhesives, Chemical, Confectionery, Carbon Black, Ceramic, Dyes & Pigments, Food Products, Grease, Lead Storage Battery, Paint, Putties, Plastic, Pharmaceuticals, Printing ink, Resin, Rubber, Soap & Detergent etc.

Sigma Mixer consists of two counter-rotating blades in two semi-cylinders, the intersection of which forms a saddle piece and meeting tangentially just above the saddle the blades are driven by gearing at both ends. The mixing action is a combination of bulk movement, smearing, stretching, folding against the blades and sidewalls. The blades, which are ground and polished, successively sweep all portion of the trough surface during each revolution.

Type of Blades - 

1. Sigma Blade - Sigma blade is capable of starting and operating with either liquids or solids or a combination of both. Sigma Blades give shredding or wiping effect. It 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. 
2. Double Naben - In specific applications a lump bridge across the two sigma blades is formed. To avoid the formation Naben blades are used.

Special Features of Sigma Mixer - 

• DISCHARGE - 
  1. Tilting tank. For small machines Tilting is mechanical type (hand-lever or hand-wheel). For bigger machines Tilting is electromechanical or hydraulic. 
  2. Extrusion screw. The extrusion-discharge screw is situated at the centre of the bottom part of the saddle under two sigma blades. During the mixing the screw pushes the material towards the sigma blades ensuring uniform mixing. At discharge time, the direction of rotation of the screw is reversed and the mixed material is extruded out of the machine. Separate drive is provided for this Screw. 

• CORED BLADE - Hollow blades to enable internal cooling or heating 

• Overlapping Blades 

• Vacuum Design, Cover Design is optional 

• Provision for HEATING or COOLING (Jacket) as per process requirements 

• Capacity - 25 Ltr. to 2500 Ltr. 

• Constructed of SS 316, SS 304 and carbon steel
