AVTAR Dispersion Kneader 'AVTAR' Dispersion Kneaders are ruggedly designed for the mixing of different kind of materials ranging from low viscosity adhesive to high viscosity polymers.
Applications : - Rubber Compounds & End Products
Natural Rubber, Synthetic Rubber Mastication of NR, IIR, SBR, CR, EPDM, Fluorine Rubber, Silicone Rubber. Rubber Tires, Packing Gaskets, Hose, Belts, Shoe Sole, Sponge, Electric Wire Covering, Casters, Golf Balls, Oil Seal, Weather Strips, Water Proof Sheet, EVA, Thread Compound Battery Containers etc. - Plastic Compounds & End Products
HDPE, LDPE, PP, PVC, ABS, PS, EVA Thermoset plastics compounds & profiles wire covering, BMC etc. Salient Features : - Maximum Dispersion & High Production
Double blades, proper clearance and high cooling effect gives excellent dispersion which can not be obtained form a open roll mill. Its production is 4-5 times more than an ordinary mixing-mill thus saving on labour and electricity. - No Foundation Required
The kneader has a common bed-plate for all parts and required no foundation. - Easy Cleaning & Colour Change
Mixing chamber can be tilted which enables easy cleaning, because of this, different coloured compounds can be made without trouble. - Easy Operation
Easy operation with push-buttons and handlever valves from the operating board. - Short Mixing Time
Mixing time ranging from 6 to 12 minutes depending on compound's specific gravity. - Accident Proof
No chance of an accident as on open roll-mill. Comparison Chart:

| Construction
Mixing Chamber : The mixing chamber is made from alloy steel & is a 'W' shape through which the rotors are assembled. The contact surface of the chamber is stelite welded & wear resistant hard chrome plated. Special steel jacket is provided for cooling & steam for heating. The rotors are coupled with special quality rotary joints to take water or steam.
Pressure Lid : This is made from alloy steel & is fitted with special pneumatic cylinder to press the material to be mixed. Wider surface area is provided which allow the ingredients being mixed to turn & move in the chamber freely. An arrangement for water or steam circulation is provided & the surface is hard chrome plated.
Dust Collector : Dust collector is provided to collect spurt powder during mixing & this collected powder can further be used in mixing, hence saving of waste material.
Electrical Control Board : A powder coated, dust proof electrical panel box is provided fitted with voltmeter, ampere meter, temp. indicators cum controller, contactors, timer, buzzer, emergency button, interlocking provision, on/off switches for motors, hand operated valves, overload relay etc.
Bed Plate : The machine has common bed on which all components are arranged in proper manner by which there is no need of foundation. (NOT REQUIRE FOUNDATION BOLTS ONLY FLOOR LEVEL SOLID RCC ) |
