In the production of many chemical products, operations such as kneading, mixing, vulcanization, and polymerization of high-viscosity and elastic-plastic materials are required, such as silicone rubber, sealants, hot melt adhesives, food gum bases, etc., and the kneader is really for these operations. It is also a kind of special mixing and stirring equipment, so how do we choose a kneader suitable for production? Correct configuration and selection of the kneader can select the optimal technical equipment for the factory, with low maintenance cost, high mixing efficiency and low energy consumption, so that the limited investment can maximize the economic benefits. As an indispensable and important equipment in the development of modern I industry, kneader plays an important role in the development and production of new materials. The structure of our commonly used vacuum kneader generally adopts two blades, which are arranged in a side-by-side tangent differential type arrangement. , that is, the speed of one stirring paddle is fast, and the speed of one stirring paddle is slow, so as to generate shearing force, and different paddle speeds enable the kneaded materials to be quickly sheared, so that the materials can be mixed evenly. Different types of kneaders have different structures and characteristics, so the environments used are also different. Therefore, when choosing a kneader, it must be selected according to the characteristics of the environment. Because the vacuum kneader is a kind of mixing equipment, it has different systems for different industries. According to different classification methods, kneaders can be divided into the following categories: 1. The kneader can be made into ordinary type, force type and vacuum type according to the working pressure; 2. The kneader can be divided into carbon steel kneader, stainless steel kneader and special material kneader according to the material of the inner tank; 3. According to the discharging method, the kneader includes hydraulic overturning and dumping, ball valve discharging, screw extrusion discharging, and flapping plate discharging, etc.; 4. According to the design volume of the machine, it is divided into: 1-6000 liters; 5. According to the different heating medium, it is divided into normal temperature type, steam heating type, heat conduction oil oil bath electric heating type and water cooling type; 6. According to the weight of the load and the degree of impact, it is divided into standard type and aggravated strength type; Please refer to the above information at the beginning of the selection, and choose a suitable vacuum kneader model according to the formula and process requirements. After our kneader is purchased and installed, the first thing to do is to clean, decontaminate and wipe the anti-rust grease inside the machine. In addition, check whether there is enough lubricating oil at each lubricating point of the machine. If not, you need to inject lubricating oil (grease). The oil pool is lubricated and replaced every three months.
The above is about rubber machinery. If you want to know more about our company's dynamics or products, you can consult us. We also sell Dispersion Kneader, Rubber Internal Mixer, Rubber Open Mill, Two Roll Mill, Plastic Granulator and Extrusion Pelletizer.
