Powder coating and modification machine

Product Advantages

1. Modifiers and materials are precisely metered and evenly added according to the mixing ratio, ensuring instantaneous accuracy of the mixing ratio. This allows for a high coating rate with minimal coating material.
2. Product modification results in excellent, stable quality.
3. High-speed friction generates heat, eliminating the need for a heating device, resulting in low operating costs and investment savings.
4. Customized powder surface modification solutions are provided based on material properties, product applications, and user needs.
5. Widely applicable, achieving ideal results for a variety of inorganic mineral powders.

Working Principle

1. Modification Mechanism
   Basic Principles of Modification: Achieve a high encapsulation rate or modification effect with less coating material and lower cost.
   Main Functions of Surface Modification: Dispersion, Viscosity Reduction, Filling Enhancement, and Interfacial Mechanical Effects.
   Modification Methods: Surface Chemical Modification, Coating Modification, and Mechanochemical Modification.
   Modification Process Selection: Modification mechanism, modifier, modification process and equipment, process control, and product testing and evaluation.
   Different modification objectives, methods, and modifiers require different process equipment.
   
   
2. Basic Process Requirements
   The modifier is diluted with water. Measures such as dispersant, emulsifier, and spray addition are used to improve dispersion, and continuous spraying or dripping is linked to continuous powder feeding.
   Precise metering of modifier and material is required for uniform addition and feeding, ensuring instantaneous accuracy of the ratio between the two, achieving uniform and firm coating of the modifier on the powder surface, good controllability of process parameters, and stable product quality.
   System temperature and time control must meet the process conditions required by the modification mechanism or modifier to ensure sufficient modification reaction or coating.
   Equipment operating conditions are convenient.
   The use of auxiliary equipment (disintegrator or classifier) and environmental factors (temperature and humidity) are also considered.
   
   
3. Continuous Modification Production Process
   Continuous surface modification processes involve continuous feeding of materials and the continuous addition of surface modifiers. Therefore, in addition to the main modification equipment, continuous powder surface modification processes also include continuous feeding and dosing (for adding surface modifiers). Because continuous modification processes utilize different production equipment than intermittent modification equipment, they can be modified continuously in large batches.
   

Continuous surface modification processes include: eddy current mills, eddy current mills, eddy current mills, and eddy current mills.

Batch surface modification processes
Batch surface modification processes involve simultaneously feeding a measured amount of powder material and a pre-mixed surface modifier into the surface modification equipment. The surface modification process is performed at a constant temperature for a specified period of time. The treated material is then discharged and refilled for the next batch of powder for surface modification. This process is typically combined with an air classifier to separate agglomerated particles during the modification process, improving product quality.

       Batch surface modification processes include: high-speed mixing and modification machines.

5. Composite surface modification processes
   Surface modifiers are added during mechanical force application, fine grinding, or ultrafine grinding, reducing the powder particle size while chemically coating the surface of the particles.
