Silica Micropowder Preparation Line and Grinding System Solutions

Silica micropowder preparation production line and grinding system program

I. Introduction of Silica Micropowder

Silica micropowder (also known as quartz powder) is a powder material made from pure quartz (natural quartz or fused quartz) as raw material, which is processed through many precise procedures, such as crushing, picking, acid treatment, melting, grinding, fine grading and high-efficiency iron removal, etc. The product has the core features of high whiteness, low impurity, low iron content and stable physical and chemical properties. Its products have the core features of high whiteness, low impurity, low iron content and stable physical and chemical properties.

Second, the core process of the production line

This program provides a mature dry silica powder preparation system with the following core process flow:

1. Feeding and lifting
   Raw materials are transported to the buffer bin through bucket elevator to realize continuous and stable material supply.

2. Buffering and metering
   The buffer silo stores the material temporarily and feeds it accurately through the belt metering scale to control the production line throughput.

3. Preliminary iron removal
   The material passes through the cylinder magnetic separator to effectively remove the ferromagnetic impurities in the raw material and provide pure raw material for subsequent processing.

4. Fine Grinding
   The material enters the ball mill for mechanical grinding, and the fineness and particle size distribution of the powder is controlled by adjusting the grinding parameters.

5. Precision Classification
   After grinding, the powder enters into the air flow classifier, and the materials are accurately graded according to different mesh sizes through wind power sorting.

6. Finished product collection
   After classification, the qualified powder is separated from gas and solid by cyclone collector, and centralized to the finished product area.

7. Automatic Packaging
   The finished powder is measured, filled and sealed by automatic packaging machine.

8. Environmental protection and dust removal
   The whole line is equipped with pulse dust collector and induced draft fan to realize the comprehensive collection and purification of dust in the production process to ensure clean production.

9. Intelligent control
   Through the central electrical control cabinet, the entire line of equipment for automated control and operation monitoring, to ensure stable operation of the system.

V. Application Fields

With its excellent physical and chemical properties, silica micropowder is an indispensable key functional filler and raw material for many industries:

• Glass industry: flat glass, float glass, optical glass, glass fiber and other major raw materials.

• Ceramics and refractory materials: embryo and glaze materials for porcelain, and raw materials for various types of silica bricks.

• Building materials: high-performance concrete, artificial marble, cement standard sand, etc.

• Chemical industry: silicon compounds, raw materials of water glass, and sulfuric acid tower filler.

• Electronic field: high-purity silicon metal, communication optical fiber and other basic materials.

• Rubber, plastics and coatings: as a high-quality filler, it significantly improves the abrasion resistance and weather resistance of products.

• High-end science and technology: In the field of aviation and aerospace, it is used in key components and materials by utilizing its characteristics of high temperature resistance, low expansion and high insulation.

With mature design and stable operation, the system can provide customized dry/water production line solutions according to the characteristics of the raw ore and product targets (particle size, purity, yield) to meet the production needs of all kinds of materials, from ordinary fillers to high-purity electronic-grade materials.
