Introduction of mica ore processing

Mica is a kind of silicate mineral, commonly types include muscovite, phlogopite, and biotite. Mica has good dielectric, elastic, insulating, refractive, and tough properties, and is commonly used for the production of insulating materials, and in the processing of fillers for rubber, plastics, coatings, and paints. The processing of mica ore include crushing, impurity removal, sorting, drying, crushing, and grinding. Freshly mined and wet-processed mica ore has a moisture content ranging from 5-15%. This moisture will cause mica to clump, affecting crushing and screening, its insulation properties, and increasing the difficulty of storage and transportation. The best moisture content for mica in industry is 0.5-1.5%. Therefore, for subsequent processing and ensure the quality of the final product, mica must be dried first.

Working principle of mica rotary dryer

Mica rotary dryer is specifically designed for drying mica. It can dry various forms of mica minerals, such as mica flakes, mica ore, and mica powder. The mica rotary dryer consists of a drum, a lifting plate, a hot-air furnace, a driving device, etc. Hot air enters the drum from the front end, and the mica are gently turned over by a low-lift lifting plate to form a thin layer and stay, achieving efficient convection drying. The anti-adhesion design on the inner wall of the drum effectively prevents the mica from adhering.

Jiutian mica rotary dryer adopts a unique three-stage drying technology, achieving a thermal efficiency of up to 85%, which is 30% higher than traditional equipment. During the drying process, mica is fully exposed to hot air, enabling rapid evaporation of water and geatly improving drying efficiency. Also, the machine is equipped with an intelligent temperature control system, it can control the drying temperature fluctuation within ±2℃, effectively avoiding damage to the crystal structure of mica caused by high temperatures and ensuring mica quality. At the same time, mica rotary dryer is equipped with an efficient dust removal system, achieving a dust emission concentration below 10mg/m3 to meet the strictest environmental standards.

Advantages of mica rotary dryer

1. Low-temperature drying

The design temperature of mica rotary dryer is no more than 180°C. This temperature prevents heat damage and preserves the natural structure of mica.

2. Gently turn the material

The gentle lifting plate and drum design prevent mica damage and ensure stable performance of the mica.

3. Large processing capacity

It can operate continuously for 24 hours, with a processing capacity of 5-100 tons per hour, suitable for large-scale industrial mica processing.

4. Energy-saving design

Equipped with specially designed lifting plates and heat-insulating drum, it has high thermal efficiency. It supports various heat sources such as coal, biomass, heavy oil, LPG, and steam, helping to reduce energy costs.

Conclusion

The rotary dryer, when applied to mica drying, can effectively preserve its original structure and properties. After dried, mica is widely used in insulation, fillers, building materials, and other industries.
