Dry ground mica powder supplied by WANCHENG MINERAL provides several practical advantages for industrial manufacturers. The product is not only a filler but also a functional mineral material that can improve performance in many formulations.
1. Cost-Effective Functional Filler
Dry grinding is suitable for large-scale production, making dry ground mica powder a cost-effective choice for coatings, plastics, rubber, construction materials, and welding electrodes.
2. Natural Flake Structure
The layered structure of mica improves barrier properties, dimensional stability, and surface texture. It helps create a physical barrier inside coatings and composites.
3. Good Heat Resistance
Mica is naturally heat resistant and suitable for formulations exposed to elevated temperatures.
4. Electrical Insulation
Mica has good dielectric and insulation properties, making it useful in electrical and insulation applications.
5. Chemical Stability
Dry ground mica powder has stable chemical properties and good resistance to many industrial environments.
6. Flexible Mesh Sizes
WANCHENG MINERAL can provide multiple particle sizes for different applications, from coarse grades to fine powder grades.
7. Reliable Export Supply
We support global customers with stable supply, export-grade packaging, sample testing, and professional communication.
WANCHENG MINERAL provides flexible packaging solutions for dry ground mica powder according to customer requirements, order quantity, transportation method, and final market needs. Proper packaging helps protect the product from moisture, contamination, and leakage during storage and international shipment.
Common packaging options include 25kg PP woven bags, 25kg kraft paper bags, laminated bags, jumbo bags, palletized packaging, and OEM customized packaging. For export shipments, bags can be loaded directly into containers or packed on pallets for easier warehouse handling.
Storage should be in a dry, clean, ventilated warehouse. Avoid moisture, rain, oil contamination, and damaged packaging. If the product is used in coatings, plastics, or high-value formulations, customers should keep bags sealed before use to maintain stable dispersion and cleanliness.
The production of dry ground mica powder focuses on raw material selection, mechanical grinding, particle size control, and quality inspection. WANCHENG MINERAL follows a controlled production process to provide stable and reliable mica powder for industrial customers.
1. Raw Mica Selection
Selected natural mica ore is chosen according to color, purity, flake structure, impurity level, and target application.
2. Cleaning and Sorting
Raw mica is cleaned and sorted to reduce visible impurities and unsuitable materials before crushing.
3. Crushing
The selected mica is crushed into smaller pieces suitable for grinding.
4. Dry Grinding
The crushed material is processed by dry grinding equipment to obtain the required particle size range.
5. Screening and Classification
The ground mica powder is screened and classified into different mesh sizes. Oversized particles may be returned for further grinding.
6. Quality Inspection
Each batch is checked for particle size, appearance, moisture, whiteness or color, impurities, and packaging condition.
7. Packaging and Shipment
Qualified products are packed according to export standards or customer requirements.
