**細(xì)**微粉碎機(jī)蒸汽動(dòng)能磨原理：

蒸汽動(dòng)能磨是利用過熱蒸汽經(jīng)過同軸心噴嘴將顆粒加速、并進(jìn)行碰撞粉碎，粉碎后的物料經(jīng)過分級(jí)機(jī)分級(jí)，合格粉料進(jìn)入后面的收集系統(tǒng)收集，不合格物料返回粉碎機(jī)繼續(xù)被粉碎。整個(gè)系統(tǒng)蒸汽保持在過熱狀態(tài)，生產(chǎn)在全干法下進(jìn)行。

Principle of kinetic energy grinding of steam:

Steam mill is using superheated steam through the coaxial nozzle, and will accelerate the particle collision crushing, crushing the material after grading, collect the powder into the back of the system of qualified, unqualified material return to mill crushed. The steam of the whole system remains overheated and the production is carried out under full dry process.

Advantages of steam kinetic energy grinding for ultrafine fly ash and sulfur fixing ash:

1. can make full use of existing waste heat generated by steam or low temperature power generation after the back pressure steam as the driving force, can effectively reduce the powder processing cost; if the existing steam is not applied on emptying, powered by steam after grinding, powder processing costs will only flow grinding cost 1/5-1/8;Energy saving advantages, in the conditional place, the use of low-grade energy is far more significant than the use of advanced energy saving.

2. crushing strength contrast: conventional gas mill design line speed of 400m/s~600m/s, while the steam kinetic energy mill crushing strength can reach 1000m/s.

3. the full use of waste heat, in line with the current state vigorously advocated energy-saving emission reduction policy requirements, easy access to government funding for science and technology and national science and technology incentives;

4. steam power grinding material and the material is crushed to collide with each other, small wear equipment, such as a large foreign body in raw materials (iron bolts, etc.) into the device will not cause damage to the equipment, low maintenance rate, few wearing parts, low maintenance cost;

5. the processing powder size range is wide, 10um superfine powder can be processed, but also can be processed according to the needs of 1 ~ 2um of ultrafine powder.

6. make full use of not used superheated steam, in line with the current state vigorously advocated energy-saving emission reduction policy requirements, easy access to government funding for science and technology and national science and technology incentives;

Equipment features:

1.low energy consumption, can make full use of the existing waste heat generated by steam or low temperature power generation after the back pressure steam as the driving force, can effectively reduce the powder processing cost; if the existing steam is not applied on emptying, powered by steam after grinding, powder processing costs will only flow grinding cost 1/5-1/8; energy saving the advantage, in some places, with lower energy than using advanced energy saving energy.

2. crushing strength, can obtain finer powder: critical velocity of superheated steam, crushing strength, easy to obtain ultrafine powder more fine, can realize the processing of submicron or nanometer powder of some material, conventional jet mill line design speed of 400m/s~600m/s, and the steam mill crushing strength of kinetic energy can reach 1000m/s.

3. steam power grinding material and the material is crushed to collide with each other, small wear equipment, such as a large foreign body in raw materials (iron bolts, etc.) into the device will not cause damage to the equipment, low maintenance rate, few wearing parts, low maintenance cost;

4. in the processing of flammable and explosive powder (such as coal / coke) in the process of safety, material is crushed in the superheated steam, so there is no danger of explosion; powder and processed can be maintained at a temperature of 40-80 DEG C to improve combustion efficiency;

5. the processing powder size range is wide, according to the needs of processing 100 mesh to 12500 powder.

6. make full use of low grade thermal power plant superheated steam as the driving force, low cost, super fine powder processing scale, conform to the state is vigorously promoting energy-saving emission reduction policy requirements, easy to obtain government funding of science and technology and support of the national science and technology award.
