Information About Fly Ash |Professional Fly Ash Ultra-fine Mill

Fly ash ultrafine mill is specially used to grind tiny ash particles with particle size between 1~100μm during coal combustion. Adding limestone, calcium carbonate and other additives, it can be processed into finished products of 7-45μm. A finished particle size of 3μm can be obtained after secondary classification. For more information on fly ash, see below.

Why are the colors of fly ash different?

HCMilling(Guilin Hongcheng) has received many inquiries from customers: Why is the fly ash I see on the Internet milky white, but the fly ash produced by the fly ash ultrafine mill I purchased is gray and black? In fact, these two colors are fly ash. The color of fly ash reflects the carbon content and fineness of fly ash. In general, fly ash varies from milky white to gray-black. Milky white to gray-black varies. The darker the color of fly ash, the finer the particle size of fly ash, and the higher the carbon content.

Are fly ash classification and grading properties the same?

According to the content of free calcium oxide in fly ash, it is usually divided into F type (low calcium ash), C type (high calcium ash) and composite ash. According to the fineness of fly ash, it is usually divided into grade I, grade II and grade III.

First-class fly ash fineness: refers to the sieve allowance of 45μm square hole sieve not more than 12%, that is, the 45μm pass rate often said in the micropowder industry is 88% (45μm is equivalent to 325 mesh)

Secondary fly ash fineness: the allowance of 45μm square hole sieve is not more than 20%

Three-level fly ash fineness: the allowance of 45μm square hole sieve is not more than 45%

What are the application conditions of fly ash in the cement industry?

Cement materials incorporating fly ash are often named Portland cement. Its own strength is much higher than that of cement without fly ash, and the fly ash needs to be ground to about 200 mesh (0.08mm) before the cement clinker, gypsum and other materials can be mixed and applied in the cement.

Why choose fly ash ultra-fine grinding for processing fly ash?

Fly ash ultra-fine mill breaks through the bottleneck of ultra-fine powder processing capacity, can replace imported equipment, and can be ground into finished products of 7-45 μm at one time.

Advantages：

1. High efficiency and energy saving: The principle of material layer grinding is adopted, which has high grinding efficiency, low energy consumption and large single-machine production capacity.

2. Convenient maintenance and low operating cost: low wear and tear, the grinding roller and grinding disc lining are made of special materials, and the service life is long.

3. High degree of automation: automatic control technology adopts German Siemens series PLC, equipped with automatic control system, which can realize remote control;

4. Product quality is stable: the product has uniform particle shape, narrow particle size distribution, good fluidity, and strong product adaptability;

5. The equipment has strong applicability and low investment: with secondary classification, it can produce 325 mesh-2500 mesh powder, realize multi-purpose equipment, strong equipment practicability, and save investment costs.

6. Environmental protection: The pulverizer system is sealed as a whole, operates under full negative pressure, and has no dust spillage. It can basically realize a dust-free workshop.
