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.
