Characteristics and uses of ultrafine fly ash

Ultrafine fly ash is a special type of fly ash with an average particle size of less than 10μm, so it is also called micro-fine fly ash or nano fly ash. It has a high specific surface area, high activity, good adsorption performance, lightweight, heat preservation, and environmental protection. As a new type of mineral admixture, ultrafine fly ash has special applications in concrete and mortar. So what equipment is used to process ultrafine fly ash?

What equipment is used to process ultrafine fly ash?

1. Ball mill: This is a traditional grinding equipment suitable for grinding materials of various hardness. In fly ash processing, the ball mill can fully grind and crush the raw materials to obtain fly ash with finer particle size.

2. Raymond mill is a grinding equipment widely used in mines, cement plants, chemical plants, and other fields. It is one of the important equipment for deep processing of non-metallic minerals. It is mainly used for high-fine powder processing of hundreds of materials such as non-flammable and explosive mineral products, chemical raw materials, and building materials with Mohs hardness not more than 9.3 and humidity below 6%. It has the advantages of stable performance, strong adaptability, and high-cost performance. The finished product fineness can be arbitrarily selected between 0.18-0.038mm (80-400 mesh).

3. A High-pressure suspension roller mill is a grinding equipment widely used in metallurgy, building materials, chemical industry, mining, highway construction, water conservancy hydropower, and other industries. It is particularly suitable for processing various non-flammable and explosive mineral materials with humidity below 6%. The finished product particle size can be adjusted between 0.613 mm and 0.033 mm, and it can also produce 30-80 mesh coarse powder by adding special devices.

4. SRM vertical mill is a large-scale grinding equipment integrating fine crushing, drying, grinding, powder selection, and conveying. It is widely used in cement, electric power, metallurgy, chemical industry, non-metallic minerals, and other industries for grinding and ultra-fine grinding of various solid materials.

Characteristics and uses of ultrafine fly ash

1. Cement concrete admixture: Ultrafine fly ash can be used as an admixture for cement, mortar, and concrete to improve the stacking degree of the overall cementitious material system of concrete and the hydration degree of fly ash, refine the pore size, and thus improve the strength and durability of concrete.

2. Road construction: Ultrafine fly ash can be used for roadbeds and pavement materials in road construction to improve the strength and durability of roads.

3. Environmental protection: Ultrafine fly ash can be used in wastewater treatment, waste gas purification, and other fields, using its excellent adsorption properties to remove harmful substances and protect the environment.

4. Building insulation: Ultrafine fly ash can be used as a raw material for building insulation materials and used to produce insulation bricks, insulation boards, and other products.

How much does an ultrafine fly ash mill cost?

The ultrafine fly ash mill price depends on factors such as equipment type, specifications, brand, and manufacturing process. When purchasing equipment for processing ultrafine fly ash, in addition to considering price factors, it is also necessary to consider factors such as equipment performance, quality, and after-sales service to ensure the normal operation and production benefits of the equipment. For specific price information, it is recommended to consult relevant equipment suppliers or refer to market price information for comparison and selection.
