End, it is widely used in the industries such as cement, electric power, metallurgy, chemical industry.Slag vertical-mill mainly by transmission device, hydraulic means, mill 1,
Grinding roller 2, lower shake-changing arm 3 and brake 4 form, and the gap wherein between mill 1 and grinding roller 2 forms milling zone 6, block and graininess
Raw material obtains the powder of required granularity after grinding roller 2 and mill 1 are ground.Slag vertical-mill in use, mill 1 and grinding roller
2 abradant surface can progressively wear with the increase of milling time, so that the gap increase between mill 1 and grinding roller 2, this meeting
The mill efficiency of slag vertical-mill is influenceed, reduces yield, product quality also cannot be guaranteed, thus need to adjust mill regularly
Gap between 1 and grinding roller 2.The structure of grinding roller 2 and mill 1 in currently used slag vertical-mill is shown in Figure 1, lower shake-changing arm
3 middle part is articulated with the support shaft 5 of the frame of slag vertical-mill, and the epimere that grinding roller 2 is fixedly installed on lower shake-changing arm 3 is anterior, braking
The head 71 of screw rod 7 in device 4 presses on the hypomere rear portion of lower shake-changing arm 3, is needed when the gap between mill 1 and grinding roller 2 increases
, it is necessary to first remove the parts such as the bolt on brake 4, anti-rotation fixed plate, then rotary screw 7, make screw rod 7 during adjustment
Head 71 is moved backward, and now lower shake-changing arm 3 makes the hypomere swing backward of lower shake-changing arm 3, the epimere of upper rocker arm 3 under gravity
Swing forward, drive grinding roller 2 close to mill 1, until the gap between grinding roller 2 and mill 1 is adjusted to stop during process set value
Rotary screw 7, the gap regulated efficiency between grinding roller 2 and mill 1 is very low, and in actual use, often has
The impurity such as grain slag, dust are fallen in the thread groove of screw rod 7, and this can cause screw rod 7 is stuck can not be rotated in brake 4,
So as to realize the adjustment of the gap between grinding roller 2 and mill 1, this external screw rod 7 is also subject to certain axial force, ridge mutability
Shape, also results in that screw rod 7 is stuck can not to be rotated in brake 4, so as to it can not realize between grinding roller 2 and mill 1 between
Gap is adjusted, and brake 4 is changed very frequently, considerably increases maintenance cost.
