Characteristics of the kneader and its heater


The series produced by FRANLI is a new type of high-efficiency, high-precision special particle kneader, the kneader is sealed and dust-free, the operation is simple, the maintenance is convenient, and the service life is long.

Details of Kneader

  • The machine comprises a motor, cover press, main body, mixing chamber and rotor mechanism, gearbox, air control system, tilting machine, heating/cooling system, rubber belt transmission and base, etc.
  • The kneader can be made into vacuum, pressure, atmospheric, Normal temperature, high temperature, low temperature, etc. 
  • The temperature adjustment method of a kneader can be the jacket, halfpipe, far-infrared tile, steam, hot water, heat transfer oil, electric heating, cooling water, chilled water, and other methods. 

Application: Paint, Adhesive, Battery, Pharmaceutical industry, Cosmetic

When the kneader flows through the wall of the device and various fixed components installed in the container, it is also subject to shearing action. These shearing actions will cause many local eddy currents to diffuse. The combination of revolution and rotation in the kneader forms four flow forms of the powder: convection, shearing, diffusion, and infiltration. Combined compound exercise.

The mixing, heat transfer, mass transfer (including devolatilization), and reaction of high-viscosity fluid in kneader are one of the focuses of stirring technology research in recent years. For low-viscosity liquids, traditional propulsion, paddle, and turbine impellers can solve the problem. In the table, the anchor and frame impellers cover a wide range of viscosities. But as mentioned above, the kneading effect of the anchor wheel in the higher viscosity range is much worse than that of the screw belt, and in the low viscosity range, its shear stress is not enough, and the axial circulation is also very poor, and due to the impact of the blade diameter on the relatively large groove diameter leads to the large volume of the solid 1.1 rotation part, so only the mixing machine kneader groove kneader powder mixer dry powder kneader cone kneader mixer three-dimensional kneader Ribbon mixer Gravity-free kneader Spiral mixer is only used when the effect of the screw mixer is not high. However, where heat transfer is the primary purpose of stirring the soil, the anchor impeller is still very suitable.

When the kneader is stirring, the material in the kneader is moved by two rotors moving in opposite directions and performing the compound motion. The biaxial paddles drive the material to rotate clockwise along the inner wall of the tank, and the material near the axis rotates on the axis. U-shaped barrel structure, stable operation, uniform mixing, no dead angle, clean discharge, wide application range.


The kneader heater is developed and designed according to the special temperature control of the kneader. It has a fast heating speed when starting up, supercooling capacity, and precise temperature control.

The kneader can be designed as heating or non-heating according to the needs. The heat exchange methods usually include electric heating, steam heating, circulating hot oil heating, circulating water cooling, etc.

Working principle of kneader heater The mold temperature controller is composed of a water tank, heating and cooling system, power transmission system, liquid level control system, temperature sensor, injection port, and other components. Typically, a pump in the power transmission system moves the thermal fluid from a tank with a built-in heater and cooler to the kneader and the kneader back to the tank; a temperature sensor measures the temperature of the thermal fluid and sends the data to the control Part of the controller; the controller regulates the temperature of the thermal fluid, thereby indirectly regulating the temperature of the kneader.


Features of Kneader Heater

1. Simple installation (generally installed close to the reactor; if anti-riot is required, it can be installed in isolation, but the overall project will be much smaller.);
2. The operation is simple and does not require professionals to operate, as long as the operator is given simple training, it can be operated, or it can be operated by looking at the manual;
3. The heating method is cycle heating, so the medium has no loss.
4. No annual review is required.
5. It can operate under the specified operating pressure of 0.5mpa, and obtain a higher working temperature of ≤ 320°C, which reduces the pressure level of the heating equipment and improves the safety of the system.


As a professional kneader manufacturer, FRANLI has provided a complete set of mature equipment for related machines and production lines for more than 60 countries and thousands of industries in the world, and in Russia, Turkey, Spain, Brazil, Malaysia, Indonesia, and other regions, it has provided many An enterprise establishes related production lines.

Sigma Mixer: Indispensable Equipment For Manufacturing

Sigma Mixer is a type of mixer that uses a unique mixing principle to achieve an efficient blending of materials. The mixer consists of two blades that rotate in opposite directions, creating a kneading and folding action that ensures thorough mixing. The blades are shaped like the Greek letter Sigma, hence the name Sigma Mixer.
