Grinding Mill Installation, Commissioning

First, the installation of grinding mill

First, the installation of grinding mill

1 , first mill gear hanging into the pit , good attention to controlling the center of a certain height and then use the standard instrument correction "B" plane , while bolt into the hole reserved .

2 mill host installation. Installed before the base contacts the bottom surface and the cement foundation and anchor bolts connecting office rubber shock pad between the pad (see Figure 2 ), then the level of instrument calibration box -shaped base "A" plane , calibration points, four points for the cross- cross lines , while Tone , its different degrees should be less than 0.20 mm shaft , E1 - E2 is not greater than 0.1 mm shall not be parallel , "E1", "E2" The gap should be kept within 5-8 mm .

3 , pipeline equipment location and height should always plan to install , not an arbitrary change and heightening, the pipe joints should be sealed , not a leak , after fastening the phenomenon . Electrical equipment should be accurate and reliable, the components to be installed after the test machine should be carried out .

Second , grinding mill debugging (empty running test machine)

1 , the pressure spring work height ( effective height after being compressed ) the lower the pressure roller on the material the greater , the higher the yield , but should be based on the load situation of main motor , with the mill roller is small Gradually compressed . Pressure spring work height of not more than 80 , temperature should not exceed 35

2 , empty load running test machine , in the absence of load test machine, roll grinding devices should adopt a rolling prison network wire rope , roller and grinding ring to avoid contact with the impact , then the host air test machine running at least 1 hour ; Host Operation should be smooth , cabinets oil temperature should not exceed 80 , temperature does not exceed 40 . Analysis of the host machine and the direction of rotation shown in Figure 4 .

3, blower should load boot , after the load to be operating normally , and then observe its smooth operation, no abnormal noise and vibration , bearing maximum temperature of over 70 , temperature should not exceed 35 .

4 , load test machine running time of less than 8 hours , after the Raymond machine is working properly no abnormal noise machine , the pipe joints leak wind generated by the test machine again to tighten the compact solid , can be put into regular use .
