Core Applications and Technical Analysis of Modification Machines in Non-metallic Mineral Powder Processing

In the field of deep processing of non-metallic mineral powders, surface modification is a key link to enhance the added value of powder materials and expand application scenarios. The powder surface modification technology system covers modification methods, process routes, modifier formulas and dedicated equipment. Among them, the surface modification machine, as the core execution equipment, directly determines the stability of the modification process, the uniformity of the modification effect and the economy of the production process. Especially after the modification process and the formula of the modifier are determined, high-performance modification machines become the core guarantee for achieving efficient and green modification of non-metallic mineral powders.

I. Core Functions and Key Process Characteristics of Powder Surface Modification Machines

A high-quality surface modifier must simultaneously meet the three core functions of mixing, dispersion, and efficient combination of modifiers, which are specifically manifested as:

Precise mixing: Ensure that the powder and surface modifier achieve full contact at both the macroscopic and microscopic levels within the equipment;

High-efficiency dispersion: Break the agglomerated particles in the powder raw materials while avoiding secondary agglomeration during the modification process;

Uniform coating: Promote the rapid dissolution and dispersion of surface modifiers, and form stable bonds with the surface of powder particles, thereby enhancing the coating rate.
