Introduction
Screw extruding sigma kneader----the best choice for high-viscosity materials,it consists of two "U" shape container made of either Mild Steel or Stainless Steel(SUS304, SUS321, SUS316L), with jacket of Carbon Steel covering two sides for heating or cooling.
The mixing elements of the double sigma mixer are two pieces of Z type casted steel blades. They contrarily rotate inward and are fitted at close or specific clearance with the mixing chamber to finish thorough and uniform mixing. The two blades rotate at different speed(usually about3/2).
We can make different kinds of double sigma mixer according to the customer's different demands, For example, vacuum system, heating or cooling methods, feeding hole, discharging methods, changeable liner, filtration net, safety valve, view glasses, Cover opening methods and so on.
1. Working Principles:
Screw extruding sigma kneader is used to knead, mix, crush, disperse and re-polymerize high viscosity paste or elastoplastic materials, which can not be processed by the general powder mixers and liquid blenders. Screw extruding sigma kneader is the ideal equipment for all kinds of chemical products and has the merits of stirring evenly, kneading efficiently and no dead corner. The materials are scraped, stretched, folded and squeezed among the blade, slot wall, and ridge-like protrusions. The materials cycle from one end of the impeller to the other. The two mixing paddles are tangent and spin at different speeds to complet the kneading process. Tilt the slot to discharge the materials.
2. Uses:
Screw extruding sigma kneader is widely applied to produce high viscosity sealant, silicone rubber, neutral and acidic glass cement, chewing gum, bubble gum, paper pulp, cellulose, and is also used in batteries, ink, pigments, dyes, pharmaceuticals, resins, plastics, rubber, cosmetics and other industries.
3. Category:
There are four kinds of Double sigma mixer: Vacuum kneader, pressure kneader, atmospheric pressure kneader and high temperature kneader. It has three ways of discharging:Hydraulic tumbling discharge, ball valve type and screw extrusion type.
4. Characteristics:
Control and record the temperature, time, viscosity and other relevant data through the PLC in real time during production. The parts of the cylinder and the blade that contact with the materials are made of stainless steel, to ensure product's quality. The kneader can be used for the high-viscosity paste or plastic solid with poor mobility around 5000PA. S, and the jacket can be heated or cooled by the heat transfer oil or water. According to the special needs, the plant can be designed to operate in vacuum. The difference between the speed of biax is 7.52r/min, so that the material is constantly changed, fastly mixed and has a larger transfer area for unit volume.
