Nano steam kinetic energy mill

Steam kinetic energy grinding principle：

        Steam kinetic energy mill is the use of superheated steam through the same axis nozzle to accelerate the particles, and collision crushing, crushing the material after the classifier classification, qualified powder into the following collection system collection, unqualified materials returned to the grinder continue to be crushed. The steam of the whole system is kept in an overheated state, and the production is carried out under the full dry method.

Advantages of ultrafine and ultrafine pulverizer in processing ultrafine fly ash and sulfur ash by nano steam kinetic energy grinding

1. It can make full use of steam generated by existing waste heat or back-pressure steam after low-temperature power generation as power, which can effectively reduce powder processing costs; If the existing steam is not practical application is empty, the use of steam power grinding, powder processing costs will only be the airflow grinding processing costs 1/5-1/8; The advantage of energy conservation is that, where conditions allow, the use of low-grade energy is far more significant than that of high-grade energy.

2. Comparison of crushing strength: the designed linear speed of conventional airflow mill is 400m/s~600m/s, while the crushing strength of steam kinetic energy mill can reach 1000m/s.

3. Make full use of waste heat, in line with the requirements of the country's current policy of vigorously advocating energy conservation and emission reduction, and easy to obtain the support of government science and technology funds and national science and technology awards;

4. Steam power mill is made by the collision of materials and materials. The equipment has little wear and tear.

5. Wide range of powder particle size, can process 10um ultrafine powder, can also process 1 ~ 2um ultrafine powder as required.

6. Make full use of the unused superheated steam, meet the requirements of the country's current policy of vigorously advocating energy conservation and emission reduction, and easily obtain the support of government science and technology funds and national science and technology awards;

Characteristics of the equipment:

1. Low energy consumption, can make full use of steam generated by existing waste heat or low temperature power generation back pressure steam as power, can effectively reduce powder processing costs; If the existing steam is not practical application is empty, the use of steam power grinding, powder processing costs will only be the airflow grinding processing costs 1/5-1/8; The advantage of energy conservation is that, where conditions allow, the use of low-grade energy is far more significant than that of high-grade energy.

2. High crushing strength can obtain finer powder: the critical speed of superheated steam is high, the crushing strength is large, and it is easy to obtain finer ultrafine powder. For some materials, the processing of submicron or even nanometer powder can be realized.

3. Steam power mill is made by colliding materials with each other. The equipment has little wear and tear.

4. Good safety in the process of processing inflammable and explosive powder (such as coal powder/petroleum coke, etc.), the material is crushed in the whole superheated steam, so there is no risk of explosion; And after processing of powder can keep on the temperature of 40-80 ℃, to improve combustion efficiency;

5. Wide particle size range for powder processing, 100 mesh to 12500 mesh powder can be processed as required.

6. Make full use of low-grade superheated steam of thermal power plant as power to realize the processing of ultra-fine powder at low cost and on a large scale, which conforms to the requirements of the current policy of vigorously advocating energy conservation and emission reduction, and is easy to obtain the support of government science and technology funds and national science and technology awards.
