Rubber internal mixer and rubber kneading mill are two commonly used mixing equipment in rubber processing. They have their own characteristics and advantages in structure, function and application scenarios. The following is a comparative analysis of the characteristics and advantages of the two combined with the search results:
1. Characteristics and advantages of rubber internal mixer
Enclosed and efficient production
The internal mixer works in a closed, pressurized and temperature-controlled environment to avoid dust leakage and reduce environmental pollution. Its production efficiency is 2-3 times that of the open mixer, and the mixing time is only 6-10 minutes, which is suitable for large-scale continuous production.
Precise temperature control and material uniformity
The mixing chamber, rotor and other components adopt a jacketed structure, which can be heated/cooled by steam, heat transfer oil or cooling water to meet different process requirements. The optimized design of the rotor spiral angle, combined with the wear-resistant carbide coating, ensures uniform material dispersion and stable quality.
Advanced sealing and durability
The rotor shaft end adopts a lubrication-free sealing structure based on Taiwan technology, which has excellent anti-leakage performance; the inner surface of the mixing chamber is hard chrome plated (0.12-0.18mm), which has strong wear resistance and long service life. The reducer adopts military-grade 42 chrome-molybdenum steel, with high transmission efficiency and low noise.
Automation control
The electronic control system integrates a PLC device, has automatic monitoring, alarm and safety interlocking functions, supports manual/automatic switching, is easy to operate and has high safety.
Wide applicability
It is suitable for rubber products such as tires, seals, soles, and mixing of chemical raw materials such as cable materials and EVA. Models cover 20L to 150L to meet different capacity requirements.
Two.Features and advantages of rubber kneading machine
Flexibility and small batch production
The kneading machine (such as the experimental XH-401 model) is compact and suitable for laboratories or small-scale production. The effective capacity ranges from 3L to 200L, supports customized needs, and is convenient for material research and development and process verification.
Efficient mixing and convenient cleaning
The pressurized design is adopted, and the rotor is a two-edge shearing structure, which improves the dispersion of materials through high-speed shearing. The mixing chamber can be turned 140° for unloading, which is convenient for cleaning and color change, and is suitable for multi-variety production.
Energy saving and environmental protection
The new motor drive system has low energy consumption, and the mixing efficiency of some models is twice that of traditional roller machines. The fully enclosed structure reduces dust spillage and improves the working environment.
Special process adaptability
The mixing chamber can be fed with cooling water or steam to meet the mixing needs of low-viscosity materials (such as plastics and paints). Some models (such as Qingdao 35L) support automatic temperature control and time control, and the operation is precise.
Durability and convenient maintenance
The rotor ridges are welded with wear-resistant alloys, and the mixing chamber is hard chrome-plated to extend the service life. Some manufacturers (such as Dalian Yunshan Machinery) use 42 chromium-molybdenum steel rotor shafts, which have stronger resistance to bending and breaking.
Three. Comparison and applicable scenarios
Internal mixers are more suitable for large-scale, continuous production, especially rubber product companies that focus on efficiency and environmental protection (such as tire factories and cable factories)
Kneading mills focus on R&D, small batch or multi-variety production scenarios (such as laboratories and seal factories), taking into account flexibility and ease of operation
