Slag Powder Vertical Mill Trial-run Method

How to guarantee the normal trial-run of vertical roller mill and slag powder production system? 

Firstly there are lots of welding work during installation process. During this process, there is high risk of welding distortion. Once there is welding distortion, it is quite hard to recorrect it. That is dangerous for future operation of Slag Powder vertical roller mill.  

XinXiang Great wall Company optimizes the welding technology to guarantee the minimum welding distortion, the nonmetal surface texture reaches flatness requirements of 1/1000, and its parallelism and perpendicularity will be within ±0.5mm. 

Secondly, the grouting quality and technology requirements high accuracy due to its obvious operating vibration. We suggest that there should be complete grouting technology, also should be attended by owner, installation part, civil engineering part, designer. 

What’s more, grinding roller’s position correction, space adjustment between grinding rollers, deviations are key factors that influence the vertical roller mill’s vibration. The application of theodolite and balance level are not sufficient for correcting the grinding rollers positions to guarantee them to be within allowable variation. 

XinXiang Great wall Company  applies unicom span level with frame level meter to correct the grinding rollers’ position, and the accuracy can reach 0.02mm/m.
