CE Certified 75-Liter Rubber Kneader Is Driven By A Double Rib Rotor And A 110kw Motor
Rubber Kneader Introduction
Structural composition of rubber kneader
1. Mixing chamber: usually adopts jacket structure, can be passed through cooling water or steam for temperature control, the inner wall is generally plated with hard chrome to reduce wear. A pair of rotors of specific shape and relative rotation are arranged in the chamber, the surface of the rotor has spiral ridges, common ones are two-sided, four-sided, six-sided, etc., and its cross-sectional geometric shapes are triangular, cylindrical or elliptical.
2. Feeding and pressing device: It consists of a feeding hopper and a pressing device. The pressing device generally adopts a cylinder or a hydraulic cylinder, and applies pressure to the rubber in the mixing chamber through the upper push bolt to ensure that the rubber is in full contact with the rotor and the mixing chamber wall during the mixing process, thereby improving the mixing effect.
3. Unloading device: Commonly there are flip unloading mechanisms, such as arc worm gear and worm mechanism, which have strong load-bearing capacity and long service life. The mixing chamber can be flipped forward at a certain angle for unloading, which is convenient for connecting the upper and lower processes.
4. Transmission device: including main motor, reducer, coupling, etc. The main motor provides power, reduces the speed and increases the torque through the reducer, and then transmits the power to the rotor through the coupling, so that the rotor rotates at the set speed and speed ratio.
5. Temperature control system: The temperature measurement system composed of thermocouples, etc. is mainly used to measure the temperature change in the mixing chamber during the mixing process; the heating and cooling system is mainly to control the temperature of the rotor and the surface of the inner wall of the mixing chamber to ensure that the mixing process is carried out within the appropriate temperature range.
6. Sealing device: It is used to prevent the leakage of rubber and powder during the mixing process. Generally, advanced sealing methods are used, such as sealing rings made of high temperature resistant, wear-resistant, and small thermal expansion coefficient materials, and are equipped with sealing springs on the outside.
Working Principle
After adding the rubber raw materials and various compounding agents into the mixing chamber from the feeding port, the upper bolt is pressed down to apply a certain pressure to the rubber. Driven by the main motor, the two rotors rotate relative to each other at different speeds, clamping the rubber and bringing it into the roller gap, so that the rubber is squeezed, sheared, stirred and rolled by the rotors. In the process of flowing around the rotor, the rubber is sheared and rubbed everywhere, the temperature rises sharply, the viscosity decreases, and the wettability of the rubber on the surface of the compounding agent is increased, so that the rubber and the compounding agent are fully in contact. The compounding agent lumps pass through various gaps together with the rubber, are sheared and broken, and are surrounded by the stretched and deformed rubber, and are stabilized in a broken state. At the same time, the ridges on the rotor make the rubber move along the axial direction of the rotor, which plays a stirring and mixing role, so that the compounding agent is evenly mixed in the rubber.
Technical parameters:
Effective kneading capacity: 75L.
Effective mixing chamber capacity: about 170L.
Main motor power: 110KW.
Hydraulic station motor power: about 7.5KW.
Rotor speed: The common front rotor speed is 30r/min, and the rear rotor speed is 24.5r/min.
Tilting angle of mixing chamber: generally between 110°-140°.
Different rubber formulas have different mixing times: generally the mixing time is 5-10 minutes.
Cooling water pressure: 0.2-0.4MPa.
Steam pressure: 0.5-0.8MPa
Performance characteristics of 75Lrubber kneader
1.Good mixing effect: It can make rubber and various compounding agents fully and evenly mixed, improve the quality and performance of rubber materials, and ensure the stability and reliability of products.
2.High production efficiency: Compared with traditional open mills, the mixing time is short, the production efficiency is greatly improved, and the production cost can be effectively reduced.
3.Easy operation: Equipped with an automatic control system, it can accurately control the mixing temperature, time, pressure and other parameters. The operation is simple and convenient, reducing the error and labor intensity of manual operation.
4.Good environmental performance: The fully enclosed structure design effectively prevents dust flying and rubber leakage, improves the working environment, and reduces pollution to the environment.
5.Sturdy and durable: Using high-quality materials and advanced manufacturing technology, the equipment has a sturdy structure, long service life, low failure rate, and low maintenance cost
