280kw Motor 110L Rubber Banbury Mixer High Production Efficiency

280kw Motor 110L Rubber Banbury Mixer Is Characterized By High Production Efficiency

Product introduction

110L drop-type rubber mixer is a common rubber processing equipment. Here is some information about it:

1. Basic structure:
- Mixing chamber: It is the main place for rubber mixing, with a volume of 110 liters. The inner wall of the mixing chamber is usually plated with hard chrome to reduce wear, and has good sealing, which can ensure that the rubber material will not leak during the mixing process.
- Rotor: The rotor is the core component of the mixer. It is generally elliptical, integrally cast, with convex edges welded with hard alloy, and side edges and other mixing parts plated with hard chrome. The surface of the rotor is made of prismatic spirals, and the gap formed between it and the mixing chamber is variable. When the rubber passes through this gap, it will be strongly squeezed, sheared, and stretched, thereby achieving rubber mixing.
- Pressing device: It is used to press the rubber raw material into the mixing chamber to ensure that the rubber can be fully affected by the rotor and improve the mixing effect.
- Flip unloading device: It usually adopts arc worm gear and worm mechanism, which has strong load-bearing capacity and long service life. After the mixing is completed, the rubber material in the mixing chamber is discharged by turning the unloading device.
- Drive motor: Provides power for the rotation of the rotor. Its power will affect the mixing efficiency and effect of the mixer.
- Cooling system and heating system: The cooling system is used to reduce the temperature of the mixing chamber during the mixing process to prevent the rubber from burning due to excessive temperature; the heating system can heat the rubber when necessary to meet certain special processing requirements. The cooling and heating system usually adopts a jacket structure, which can be used to pass medium (such as water, steam, heat transfer oil, etc.) to achieve temperature control.
2. Working principle: When the falling rubber mixer is working, the rubber raw material is added to the mixing chamber from the feeding port. As the rotor rotates relative to each other, the raw material is clamped and brought into the gap between the rotor and the mixing chamber wall, and is squeezed and sheared by the rotor. Under the action of the convex ridges of the rotor, the rubber raw material will also move along the axial direction of the rotor to play a role in stirring and mixing. After a period of mixing, the compounding agents in the rubber raw material can be fully mixed and evenly mixed to achieve the desired mixing effect.
3. Technical parameters:
- Drive motor power: The motor power of 110L falling rubber mixer produced by different manufacturers may vary, generally between 75-220 kW.
- Rotor speed: Usually the front rotor speed is 30-36 rpm, and the rear rotor speed is relatively low. The specific value depends on the equipment model and manufacturer.
- Compressed air working pressure: Generally 0.5-0.8 MPa, compressed air is mainly used to control some pneumatic components, such as pressing devices, etc.
- Cooling water pressure: Usually 0.3-0.4 MPa, used to cool the mixing chamber and related components.
- Dimensions: The dimensions of equipment from different manufacturers will vary, but the approximate size range is 4-7 meters long, 2-3 meters wide, and 3-4.5 meters high.
4. Application scope: Widely used in the rubber products industry, such as the production of tires, rubber tubes, rubber soles, rubber seals, etc. It can be used for plasticizing and mixing of various rubber materials such as natural rubber, synthetic rubber, recycled rubber, etc. It can also be used for blending rubber and plastics and blending various low-viscosity materials.
5. Advantages:
- Large mixing capacity: It can process large batches of rubber raw materials at one time and improve production efficiency.
- Good mixing effect: The powerful extrusion, shearing and stretching effects enable the rubber and compounding agents to be fully mixed, improving the quality and performance of the rubber.
- Convenient operation: The high degree of automation and simple operation reduce the labor intensity of workers.
- Good working environment: It better overcomes the problem of flying dust, reduces the loss of compounding agents, and improves the working environment.
6. Disadvantages:
- High equipment cost: Compared with some small rubber processing equipment, the price of the 110L falling rubber mixer is higher and the investment cost is higher.
- Difficulty in maintenance: Due to the complex structure of the equipment, maintenance and repair work requires professional technicians to carry out, and the maintenance cost is high.
- Large floor space: The equipment is large in size and requires a large production space.
