Pressurized 75-Liter Rubber Kneader Hydraulically-Flipped L Mixing Chamber Water Cooling

The Pressurized 75-Liter Rubber Kneader Features A Hydraulically-Flipped L Mixing Chamber And Water Cooling

Basic Information

• Name:Pressurized 75L Rubber Kneading Machine
• Application:Primarily used in the rubber processing industry for the plasticization and mixing of rubber materials. It plays a vital role in the production of various rubber products such as tires, rubber seals, and rubber hoses.

Working Principle

• The machine operates based on the principle of shear and extrusion. Inside the sealed kneading chamber, two specially designed rotors rotate relative to each other. The spiral grooves on the rotor surfaces subject the rubber material to intense shearing, extrusion, and stretching forces. This causes the rubber molecular chains to break and rearrange, enhancing the plasticity and uniformity of the rubber.
• The pressurizing device applies pressure to the rubber in the kneading chamber, increasing the friction between the rubber and the rotors as well as the chamber walls. This further intensifies the kneading effect, ensuring the uniform mixing of rubber with various additives and improving the quality of rubber products.

Structural Components

• Power System: Consists of a main motor, reducer, and other components. The main motor, usually with a power of 110KW for a 75L pressurized rubber kneading machine, provides the power for the rotation of the main shaft. The reducer reduces the high speed of the motor to a speed suitable for the rotation of the rotors and increases the torque to meet the force requirements for kneading rubber.
• Kneading Chamber: It is the core part for rubber kneading, made of high-strength wear-resistant materials. There are two parallel rotors inside. The kneading chamber is usually of a jacketed structure, through which heating or cooling media can be passed to control the temperature during the kneading process.
• Pressurizing Device: Generally composed of components such as an air cylinder, piston, and sealing block, located above the kneading chamber. Compressed air or hydraulic oil is introduced into the air cylinder to drive the piston to move the sealing block downward, applying pressure to the rubber in the kneading chamber. The pressure can be adjusted according to process requirements.
• Feeding and Discharging Devices: The feeding hopper is located at the upper part of the kneading machine and is used to put rubber raw materials and various additives into the kneading chamber. Some kneading machines are also equipped with an automatic feeding system to accurately control the feeding quantity and time. The discharge port is located at the bottom or side of the kneading chamber. The kneaded rubber is discharged from the machine through a tilting discharge mechanism or a screw discharge device.
• Heating/Cooling System: The heating methods usually include steam heating and electric heating, while the cooling method generally adopts circulating water cooling. Through the temperature control system, the temperature of the kneading chamber can be accurately controlled according to the requirements of the rubber kneading process, ensuring that the rubber is kneaded within an appropriate temperature range.

Technical Parameters

• Mixing Capacity: 75L, indicating the volume of rubber materials that the kneading machine can process each time.
• Main Motor Power: 110KW, providing power for the rotation of the rotors.
• Tilting Motor Power: 3.75KW, used to control the tilting of the kneading machine hopper for convenient discharging.
• Pressure Accumulation Motor Power: 1.5KW, providing power for the pressurizing device.
• Tilting Angle: 110°, which ensures the smooth discharge of the kneaded rubber.
• Feeding Method: Front feeding/back feeding (F/B), allowing users to choose the appropriate feeding method according to actual production needs.
• Forward Speed of Stirring Shaft: 38/32 RPM. The rotation speed of the stirring shaft determines the mixing intensity and effect of the rubber materials in the kneading chamber.
• Reverse Speed of Stirring Shaft: 29/25 RPM.

Advantages in Application

• High Production Efficiency: The efficient kneading process can complete the mixing and kneading of rubber in a relatively short time, significantly improving the production efficiency of rubber processing.
• Product Quality Assurance: By precisely controlling parameters such as rotor speed, pressure, and temperature, the rubber materials can be fully and uniformly kneaded, ensuring the stability and consistency of rubber product quality.
• Reduced Labor Intensity: With a high degree of automation, the processes from feeding, kneading to discharging can be automated, reducing manual intervention and thus reducing the labor intensity of workers.
• Wide Range of Applications: It is suitable not only for the processing of natural rubber but also for synthetic rubber and the mixing of various rubber additives, with a wide range of applications.
