Double Z-blade Kneader Extruder

Sigma Mixer :

Ambica Boiler & Fabricator is dedicated in design and manufacture of all industrial mixing equipment!

INTRODUCTION:

The ABFSGE series Double Z-blade Kneader Extruder is used for the mixing-kneading of materials with very high viscosities (over 500,000 cps). With its unique design of Z-shaped mixing tools installed in two semi-cylinders, the ABFSGE series series Double Z-blade Kneader Extruder is able to provide combined functions of compressing, stretching, folding, kneading & mixing, which makes it widely used in the chemical, food, sealing compound and paint industries, among others.

HOW DOUBLE Z BLADE KNEADER EXTRUDER WORKS:

In the ABFSGE series Double Z-blade Kneader Extruder, there are two special designed Z-shaped rotating elements installed in a W-shaped chamber, the intersection of which forms a saddle piece and meeting tangentially just above the saddle.

 

They rotate at different speeds (usually in the ratio of 3:2) and in opposite direction. The 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 side walls. Continually new layers of material are compressed and folded over one another and are subjected to shearing forces. New surfaces are formed and the components can penetrate.

 

The blades, which are ground and polished, successively sweep all points of the trough surface during each revolution, at the same time dividing the batch continuously across the saddle piece and thereby rapidly affecting a perfectly homogeneous mix.

DISCHARGING ARRANGEMENT:

a) Tilting tank

For small machines tilt can be of a mechanical type (handlever or handwheel). For greater machines electromechanically or hydraulically powered.

b) Extrusion screw

The extrusion-discharge screw is located in the saddle section and runs in a cylindrical trough tangential to, and below the 2 mixing blades. During the mixing cycle the screw moves the material within the reach of the mixing blades, thus assuring a thorough blending of all the ingredients, and, at the same time, accelerating the mixing process. At discharge time, the direction of rotation of the screw is reversed and the mixed material is extruded through suitable die openings in the side of the machine. The extrusion screw has its own separate drive so that blades and screw operate independently.

OPTIONS:

The large number of options available for the ABFSGE series Double Z-blade Kneader Extruder enables it to perform particular functions or operate as a general kneader:

1.      Tiltable tank

2.      Bottom extruder discharge

3.      Variable speed drive

4.      Hydraulic drive

5.      Special 'Duplex' kneading arms for intensive kneading

6.      Vacuum execution

7.      Double jacket

8.      Overlapping arms

Double Z-blade Kneader Extruder is a heavy-duty mixer specially designed to produce uniform mixing, blending & kneading of highly viscous, paste & dough type materials. Sigma mixer is used for kneading of putty, epoxy, paints, pigments, adhesives, gums, battery pastes, welding electrode flux, catalysts paste, plastic compounds, rubber compounds, papad, chocolate, bubble gum, etc.
