Non-metallic Minerals Powder Coating modifying machine High Quality Surface Modification Machine

Process Features:

• Smallest coating agent to get highest coating rate.
• Both continuous process and batch process are available.
• Ocating agent includes atearic acid,coupling (Titanate Coupling,Aluminate Coupling,Phosphate Coupling and Silane Coupling).
• Several different coating machines available.
• We can supply tailored solution according to different material characters and different product application.
• Coated material has four functions:dispersion,reduced viscosity,increased filling,and interface mechanics function.
• The whole system has convenient operation,high automation,high efficiency and low production cost.
• Wide application and can achieve expected activation effect for various inorganic mineral materials.

Process Introduction:

Batch Process

High-speed Mixer + Classifier (or Mixer) Process

Process Features:

• Process: raw material would be dosed into high-speed mixer or continuous coating machine,mixed and heated (moisture < 0.3%).Coating agent would be added in liquid or after atomization.The material and coating agent get mixed in high-speed mixing.Coated powder would be sent to classifier to remove big particles.
• The choice of coating agent and dosage depend on product character,fineness (or specific surface area) and prodcut application.For example of kaolin,for 20-45 micron powder,the dosage should be 0.3%-0.5%; for 5-20 micron powder,the dosage should be 0.5%-0.8%; for 2-5 micron powder,the dosage should be 0.8%-1.0%.
• The temperature and time of coating is adjustable,and recipe can be applied in wide cases.
• In high-speed movement,material would be heated and coated with coating agent,which make material heated evenly and also improve coating rate.The dosage of coating agent reduced,and coating cost reduce.
• Classifier connected with coating machine can remove aggregate from coating effectively,and improve coated product quality and ensure performance of coated product.
• The inside of machine would be protected for wear resistance,which improve life time and also ensure purity.
