Overview
The mixing/kneading and heat transfer of high viscosity materials are particularly complex and difficult in industrial facilities, and no equipment can solve these problems in one package. The $r $n screw extruder is a typical equipment for continuously processing high viscosity materials and is widely used in polymer processing. However, the screw extruder has a small diameter, small volume, and very short residence time, making it unsuitable for processes that require long-term processing. The $r $n kneading machine is a commonly used equipment for batch processing of high viscosity materials, commonly used in the production of rubber products. Its small heat transfer area, small aspect ratio, and very wide residence time distribution limit its application in continuous large-scale industrial plants.

Mixing of high viscosity materials/kneadHeat transfer is particularly complex and difficult in industrial installations, and no equipment can solve these problems in one package.
Screw extruder is a typical equipment for continuous processing of high viscosity materials, widely used in polymer processing. However, screw extruder has a small diameter, small volume, and very short residence time, making it unsuitable for processes that require long-term processing.
Kneading machine is a commonly used equipment for batch processing of high viscosity materials, commonly used in the production of rubber products. Its small heat transfer area, small aspect ratio, and very wide residence time distribution limit its application in continuous large-scale industrial plants. In addition, the kneading machine is prone to clumping and sticking to the mixing shaft (agitator) when handling viscous and ultra high viscosity materials, resulting in ineffective mixing function.
The scraper type thin film evaporator is suitable for desolvation or devolatilization of materials with a certain viscosity, with a heat transfer coefficient higher than all other equipment, but the residence time in seconds cannot remove solvents or volatiles from high viscosity materialsOther volatile componentsWhen there is a phase change in the material, it is even more powerless.
The original horizontal self-cleaning mixing equipment has a different structureThe mixture/Kneading and heat transfer equipment have comprehensive performance that cannot be compared to other equipment when processing high viscosity materialsof
The horizontal self-cleaning mixing equipment consists of a transmission mechanism, a seal, a mixing shaft, a mixer, and a sealed container. The aspect ratio can be large or small, and it can be operated continuously or in batches. The range of equipment capacity is from2.5L—10000LThe maximum loading coefficient can reach70The maximum torque can reach200000Nm.
