Powder Surface Modification Machine

The surface modification machine operates in conjunction with the Raymond mill, connected in series after the cyclone collector. It utilizes the residual heat of the powder (60~110°C) to reduce energy consumption and improve coating efficiency, achieving uniform surface modification of the powder. This effectively reduces oil absorption value, enhances hydrophobicity and flowability, upgrading ordinary mineral powders into high-value-added functional fillers.

Features and Advantages of Powder Surface Modification Machine

Precise Coating: Integrates high-speed shearing, mechanical impact, and precise atomization technologies to significantly enhance the efficiency and quality of powder coating.

Targeted Property Design: Enables targeted control of powder properties, such as effectively reducing oil absorption, enhancing hydrophobicity, and improving dispersibility and flowability, meeting the specific functional requirements of different materials.

Composite Modification: Not only activates the surface activity of powders but also integrates the compounding and spheroidization of multiple powders, significantly expanding the application range and enhancing the added value of powders.

Eco-Friendly and Energy Efficient: Seamlessly integrates with upstream grinding equipment, utilizing residual heat from powders generated in the preceding process for modification, significantly reducing energy consumption. The entire system operates in a fully enclosed manner with minimal dust emission.

Working Principle of Powder Surface Modification Machine

Dispersion and Activation: Utilizes shearing and impact force fields to disperse powders and activate their surface crystal structures, increasing surface energy and reactive sites.

Surface Modification: Liquid modifier is atomized and uniformly mixed with the activated powders. Surface properties are precisely controlled through temperature and mechanical force regulation.

Coating and Shaping: Achieves monolayer coating through mechanical friction and performs spheroidization shaping for soft particles, simultaneously completing surface modification and morphological control.
