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.

Winner2000ZDE intelligent laser particle size analyzer, perform auto test, auto alignment, auto water supply, auto drainage, auto bubble removing, auto ultrasonic dispersion, auto cleaning etc., really realize one-key operation. It adopt full built-in sampling system, effectively prevents large particles sedimentation problems in the circulation pipeline, ensure good accuracy. It adopts comprehensive Laser diffraction particle size measurement principle with highly sensitive ring photoelectric detector improving the test accuracy greatly, Original designed unconstrained free fitting software technology, a true reflection of the particle size distribution, to ensure truth and accuracy of the test results. Therefore especially suits the laboratories of enterprises, colleges and universities and research institutes to use.

The label (Waste Oil) covers a variety of industrial (water-in-oil) emulsions.
Waste Oil (or Slopoil) can be used motor oils (crankcase oils), tankbottoms at refineries or other storage facilities, contaminated fuel oils, waste from chemical factories and many more. These are all stable mixtures (emulsions) of oil and water, often containing also other impurities like sediments and insoluble salts.
Formulated from surface active compounds, wetting agents, wax dispersants and other additives, the OWT waste oil demulsifiers are often developed tailor-made to recover the maximum of oil and remove the maximum of water and solid impurities in the shortest feasible settling time.
Especially when a certain batch of such kind of waste has to be treated, we prefer that you send us a representative sample (approx. 3-5 ltrs) of this emulsion together with a description of the process conditions: treatment-temperature, settling or mechanical (centrifuge) separation process, etc.
In our laboratory we will then select the best cost-performing demulsifier to treat this particular batch, and advice you what goals are obtainable within the shortest possible time limit. This evaluation will be free of charge.
