This sigma mixer machine is used for kneading, mixing, curing and polymerization of high viscosity and elastic-plastic materials. The kneader mixer can be used to produce silicone rubber, sealant, hot melt glue, food glue base, medicine preparation and so on. These sigma mixer machine are a special kind of mixture mixing equipment, they are commonly adopt two Σ blade, using tangent type differential arranged side by side at different speed, which enables the mixing of the material to shear quickly, so that the material can be mixed evenly. The kneading reactor is a horizontal mixing machine with two Sigma, or Z-type blades. These blades are driven by separate gears at different speeds, one running faster than the other. The reactor has one powerful motor and a speed reducer to drive the two blades. The kneader reactor usually has a W-type barrel with a hydraulic tilt that turns it, and a heating jacket outside. Application: Our kneader reactor is one ideal equipment for kneading、mixing、crushing、dispersing and re-polymerizing high viscosity materials or elastic-plastic materials such as rubber, silicone rubber, adhesive, resin, high viscosity sealant, glass glue, chewing gum, bubble gum, toothpaste, paints, dyes, pigments, printing ink, hot melt adhesive sealant, Plastics, pharmaceuticals, paper pulp, carbon fiber, cosmetics, battery, food stuff, etc. Configuration: 1. Volume: 5L-5000L 2. Material: Stainless steel 304 / 316L, Carbon Steel 3. Condition: New condition, 100% manufactured by Laizhou Newhongda 4. Stirring paddle: Sigma / Z-shape blades 5. Speed control: PLC system with inverter to control the paddle rotating speed as request 6. Optional type: Normal kneader / Vacuum kneader / Pressure kneader 7.

Structure of Kneader Mixer Machine

Working Principle of Sigma Mixer

The working principle of sigmal mixer machine is same with the rubber mixing machine ,it is highly popular mixing equipment used for efficiently mixing and kneading high viscosity materials with utmost ease by ‘Z’ type (SIGMA) shaped kneading blades. In the sealed mixing chamber, under the pressure of upper ram, the two blade rotates very accurately at different speed towards each other. These high-viscosity materials would be plasticized or mixed into the new required material by shearing, squeezing, stirring, rolling and other kneading.

Operation of Sigma Blade Mixer

Firstly, the material to be mixed is fed through the top of the kneader mixer’s container , about 40 to 65 percent of the mixer’s total volumetric capacity. The inner blades are rotating through heavy duty drive systems,which mainly consist of a motor, gearbox, couplings, and gears. The speed of rotating blade can reach up to 60 metres per minute. Basically , the mixing homogeneity upto 99% within 10 to 30 minutes. The mixer troughs can be provided with jackets for circulation of hot or cold media to maintain the required temperature conditions within the k eader mixer machine. The discharge of the material from the kneader mixer container is either by tilting of the mixer container, bottom discharge valve or through an extruder / screw located in the lower portion between the two trough compartments. The tilting arrangement of the container may be designed for manual operation or may be mechanized using motorized or hydraulic arrangement.
