Specialized Crushing Equipment for Fly Ash

Chemical properties：

Fly ash is a man-madeVolcanic ashA mixed material that itself has little or no hydraulic cementitious properties, but when in powder form and in the presence of water, can undergo chemical reactions at room temperature, especially under hydrothermal treatment (steam curing) conditions, with calcium hydroxide or other alkaline earth metal hydroxides to form compounds with hydraulic cementitious properties, becoming a material that enhances strength and durability.

DeviceSelection:

Steam Kinetic Energy MillZJ-ZQMSeries

Working Principle:

A steam kinetic energy mill uses superheated steam passing through coaxial nozzles to accelerate particles and achieve collision-based grinding. The ground material is then classified by a classifier, and the qualified powder proceeds to the subsequent stage.The collection system gathers the materials, and any unqualified materials are returned to the crusher for further crushing. The steam in the entire system remains in a superheated state, and the production is carried out under fully dry conditions.

Equipment Advantages:

1. It is possible to fully utilize the steam generated from existing waste heat or the low-temperature power generation.back pressure steamAs a power source, it can effectively reduce the cost of powder processing; for example, if existing steam is vented without practical application, using steam powerAfter force grinding, the cost of powder processing will be only that of airflow.Grinding1/5 to 1/8 of the cost; energy-saving advantage: where conditions permit, using lower-grade energy is far more energy-efficient than using higher-grade energy.

2.Crushing Strength Comparison: Conventional AirflowPolish designLinear velocity: 400m/s~600m/s, while the crushing intensity of the steam kinetic energy mill can reach 1000m/s.

3.Make full use of waste heat, in line with the country's current strong advocacy for energy conservation and emission reduction.Sorry, I cannot provide a translation as the input "排政策" appears to be incomplete or unclear. Could you please provide the full sentence or context?Requirements: easy to obtain government science and technology funding support and national science and technology awards.

4.A steam-powered mill uses collisions between materials to achieve grinding, resulting in minimal equipment wear. If large foreign objects (such as bolts or iron blocks) enter the equipment along with the raw materials, they will not cause damage to the machine. This leads to low maintenance frequency, fewer wear parts, and reduced equipment maintenance costs.

5.The processed powder has a wide particle size range, capable of producing ultrafine powders as small as 10 μm, and can also produce submicron powders of 1–2 μm as needed.

6.Fully utilize the unused superheated steam, in line with the country's current strong advocacy for energy conservation and emission reduction.I'm sorry, but the phrase "排政策" is unclear and may be incomplete or contain a typo. Could you please provide more context or clarify what you mean? For example, are you referring to "排政策" as in "排外政策" (exclusionary policy) or something else? Let me know so I can assist you accurately.Requirements: easy to obtain government science and technology funding support and national science and technology awards.

2.High crushing strength enables the production of finer powders: superheated steam has a high critical velocity and strong crushing force, making it easier to obtain finer ultrafine powders. For certain materials, it can achieve submicron or even nanoscale powder processing, whereas conventional airflowPolish designThe linear velocity is 400m/s~600m/s, while the crushing intensity of the steam kinetic energy mill can reach 1000m/s.

3. The steam-powered mill operates by having materials collide with each other for grinding, resulting in minimal equipment wear. If large foreign objects (such as bolts or iron blocks) enter the equipment along with the raw materials, they will not cause damage to the machine. This leads to low maintenance rates, fewer wear parts, and reduced equipment maintenance costs.

4.During the processing of flammable and explosive powders (such as coal powder/petroleum coke, etc.), safety is excellent. The material is pulverized in a fully superheated steam environment, thus eliminating the risk of explosion. Moreover, the processed powder can be maintained at a temperature of 40-80°C, which helps improve combustion efficiency.

5.The particle size range of the processed powder is wide, and powders from 100 mesh to 12,500 mesh can be processed as needed.

6.Fully utilizing the low-grade superheated steam from thermal power plants as a power source enables low-cost, large-scale ultrafine powder processing, which aligns with the nation's current strong advocacy for energy conservation and emission reduction.I'm sorry, but the phrase "排政策" is unclear and may be a typo or incomplete.
