Dispersion Kneader
 This
is the most commonly used mixer in the rubber & plastic Industries.
With its unique design through material flow & controlled shear
mixing achieves a uniform compound mixture with best dispersion of
materials.
Applications :
Shoe-sole, Rubber Chappal or Footwear, Micro-sheet, Tyres & Tubes,
Tread compounds, Rubber Hose, Sports Ball , EVA, Chloroprene Rubber,
Conveyor Belts, E.P.D.M., Silicone Rubber, Plastic Compounds, Battery &
Plastic Blends, Motor parts etc.

CONSTRUCTION :
1. Mixing Chamber & Rotors :
The Mixing Chamber is fabricated from alloy steel & is W-shaped.
The chamber is fitted with two rotary blades. The surface is
hard-chromed and has a provision for a jacketing the inlet of water for
cooling & steam for heating. The rotors are also made of special
steel. The rotors are hard chromed, after the tips of the rotary blades
are welded with stelite. These blades are coupled with rotary joints
thus enabling to take steam or water.
2. Chamber Tilting:
The process of tilting is done mechanically by driving the separate
electric motor. The motor is controlled by electrical push buttons
fitted in the control panel, which makes the operation easy. Chamber is
tilted at an angle of 120° which ensures all the raw-material
dropping out very quickly. Tilting can be adjusted at an angle or 10°
plus minus.
3. Dust Collector:
It helps to collect spurt powder during mixing and powder can be
re-used thus saving of the material wastage.
4. Electrical Control Panel:
This is fitted with Voltmeter, Ampere Meter, Temp.Indicator cum
Controller, L & T Controllers, Timer, Buzzer, Hour Emergency Switch,
Complete Inter Locking provision, different ON/OFF switches individual
for all motors, hand operatied valves, MCB's, Overload Relay, FRL Unit,
Main Line Indicators etc.
5. Thermo Couple:
It is provided into the main chamber by which compound temperature
measurement can be done more accurately.
6. Accessories:
Dust Collector, Air Filter Regulator & lubricator Unit, Air- Gun
for quick cleaning of machine, Gear Covers, Hand Operated Oil Pump,
Water Pump.
