The processing technology of mica powder

Mica powder can be divided into two types according to processing technology: dry process and wet process.

At present, the production equipment of dry and wet process sericite powder in China is replaced by other mining production machinery, which is actually a simple and complex production process, resulting in high production costs.

1. Raymond grinding processing

Mineral processing - rough crushing - processing - grinding - grading - packaging - finished products.

The mica powder content of this product can reach over 70%, making it suitable for use in industries such as mid to low grade paints, exterior wall coatings, anti-corrosion and fire retardant coatings, marine coatings, rubber, welding rods, cables, etc., with good results.

2. Adopting a new process - airflow purification and classification processing

Mineral processing - rough crushing - processing semi-finished products - purification - grinding - grading - packaging - finished products.

This process separates mica and quartz, resulting in highly purified mica powder with a mica content of over 95%. The technical indicators of this product can meet the standard of wet mica fine powder. This advanced equipment, under automated control, standardizes the production of mica fine powder, preserving the unique flake like structure of mica ore, with a high aspect ratio and excellent quality in all aspects. Mica powder is suitable for use in high-end exterior wall coatings, powder coatings, anti-corrosion and fire retardant coatings, ship coatings, multifunctional paints, and coatings, with good results.
