High-Speed Mixing Powder Coating and Modification Process

Product Description

Three-roller Mill Realize powder surface modification by changing inner vortex with three rotating rotors. Mature technology, low investment, suitable for stearic acid coating. Self-friction generates heat, no heating device is needed, less auxiliary machine, and low operating cost. Suitable for powder coatings of 325~1250 mesh. Power range: 11kW~225kW; Maximum output: 6t/h. Disadvantages: The air volume is small, the dispersibility is poor, especially the fine powder, and the amount of modifier is large. Self-friction heat generation is easily affected by environmental factors, and the modification temperature is poorly controllable. There is a dead zone and the coating rate is low. Features and Advantages Wide Range of Applications The ideal coating effect can be achieved for various inorganic mineral powders. High Coating Efficiency The highest cladding ratio or coating effect is achieved with minimal coating material or cost. High Automation The entire system is easy to operate, high efficiency and low cost. Flexible Production Process According to material characteristics and customer request, a continuous production process or a batch production process can be selected. Rich equipment selection Has variety of options for different processes. Customizable Solution Provide technical consultation and personalized solutions for coating process according to material characteristics and product use.
Working Principle
Coating mechanism
1. The basic principle of coating: obtain the highest coating rate or coating effect with the minimum coating material or cost;2. Surface coating of mineral fillers, the main functions include dispersion, viscosity reduction, filling, and interfacemechanics;3. The most commonly used coating methods are: surface chemical coating method, coated coating method, mechanical force chemicalcoating method;4. The coating methods mainly include: coating mechanism, modifier, coating process and equipment, process control, product testing and evaluation;5. If the purpose, method and modifier of the coating are different, the process and equipment are also different.Basic Process Requirements
1. The modifier uses dilution, emulsification, spray addition and other measures to improve the dispersion, preferably continuous spray or drip with the continuous feeding of the powder;2. Precision metering and uniform feeding of modifier and materials to ensure the instantaneous precision of the ratio of the two, to achieve uniform and firm coating of the modifier on the surface of the powder, good controllability and stable product quality;3. The regulation of the temperature and time of the system should meet the requirements of the coating mechanism or the modifier on the process conditions, and ensure the sufficiency of the coating reaction;4. the equipment operating conditions are good;5. The use of auxiliary equipment (deagglomerator or classifier), environmental factors (temperature, humidity), etc.
