Device Performance: The adoption of separator blades in axial side and the enlargement of the interspace in disc tube greatly improve the regularity of coal powder as well as reduce the times of powder circulation. Compared with the former radial type pulverizer, the present one can elevate the power of coal grinding, reduce the resistance in separator and eliminate electricity consumption.Structure feature: *Larger separator’s volume, lower volume intension; *axial type fold door with a Max. opening angle of 45 degrees; *flowrate from inlet to outlet varies from 18 to 20M/S to reduce its resistance; * an conical and movable cap on inner cone can help to adjust the granularity of coal powder roughly; * powder recycling device of inner cone adopts fencing type and crevice type structure, crevice type structure is recommended by us; * fold door and the adjusting pole of conical cap should be regulated respectively. Applications: *it is designed specially for medium-grade soft coal, but all kinds of coal are applicable ( R90 range is 6-28%.); * resistance coefficient ￡=5-7; * both explosive and anti-explosive are available ; * coal powder degree coefficient ￡>5.Specification Selection: at first, according to the quality of coal, the powder granularity R90 should be chosen as the standard of pulverizing system. Then calculate its volume intensity QTF/V according to formula (1), its value varies within the following data.

R9O %	4-6	6-15	15-23	28-40
QTF/V cubic meter /n cubic meter	900-1100	1100-1500	1500-2000	2000-2600

2、From the top of the cyclone separator, we can see that the counterclockwise entrants of the coal powder air mixture are levorotary（Z）；clockwise entrants are levorotary（Y）. The icons in this manual are levorotary（Z）.
3、The company can manufacture four kinds of fine powder separators; of which HWB-XZ Type and HW-XBY Type are used for the explosive fuel and HW-XFZ Type and HW-XFX Type are used for the non-explosive fuel.
4、The upper part of the separator can be regulated to any angle.
5、The load of the buttress, stent platform, etc will be designed by the design company.
6、Fine powder separator specifications (see annex)
7、Selection of fine powder separator

：Vty-ventilation m³/s
HW-XB-I Series fine powder separators are much higher. The outer cylinder cross-section calculation flow rate is 3 ~ 3.5 m / s. You should follow the following way to choose powder separator diameter.
