It crosses and is welded and fixed, the contact area being welded and fixed is big, and connection more fastens, and is such as screwed, and fixed point is relatively fewer, and
It is in wind for a long time to sweep in environment, screw is easy to wear away, and causes to fall off between connector.
Preferably, in a kind of above-mentioned vane device for slag vertical-mill, the spacing of the first passage is 10-
15mm, one of them is the rotating member of rotation to two components being related to due to this distance, another is static static element, such as
Fruit distance value is too small, and there are the danger that two pieces bumps against；Good lock wind effect is not had if distance value is excessive.
Preferably, in a kind of above-mentioned vane device for slag vertical-mill, the vane calibrated bolck and the adjustment plate
The T-shaped structure in joint, and shortest distance is 10-15mm between the vane calibrated bolck and the mill.
It can be seen via above technical scheme that compared with prior art, it is vertical for slag that the present disclosure provides one kind
The vane device of mill, changing traditional vane device, installation is inconvenient as caused by numerous plates change vent area, it is numerous to repair
Phenomenon trivial, Boiler pressure control is inaccurate, mill interior air-flow operating condition is unstable；
Vane device integral manufacturing disclosed by the invention is technically simple, dismounting is convenient, easy to maintenance, safe and reliable, practical
Property it is wide, according to Specific construction situation, pass through the reasonable arrangement to adjustment plate position, change the wind of outlet air open area and air outlet
Speed realizes the screening function to material after grinding；The position between baffle of the present invention, vane calibrated bolck and mill is closed simultaneously
System ensure that the smooth circulation of air-flow between mill and vane calibrated bolck, realize that mill interior air-flow operating condition is normal.
