Matters in installation of ball mill bearing

Mobile jaw crusherzk-ballmill,Ball mill main bearing bottom plate processing surface should be located in the same horizontal plane, the installation is available when liquid together with the device or level, level measurement, the longitudinal and transverse horizontal deviation not greater than 0.1mm / m, two floor relative height difference is less than 0.Vibrating grizzly feeder5mm, and the feed end higher than the discharge end.coking coal processing plant Ball mill bearing plate of the longitudinal center line of the coaxial error is not more than 1mm, the transverse center line of parallelism error no more than 0.5mm / m.

Mobile jaw crusher font-size: 9pt">Ball mill bearing on the spindle bearing base plate, so that the two center line, the bearing and the bearing seat contact surface along their sides should be uniform contact, local clearance shall not be greater than 0.1mm,Cement making machine does not contact the edge length shall not exceed 100mm, the cumulative length of no more than around 1 / 4 of length, otherwise, should be treated.portland cement manufacturing

The main bearing assembly accessories to find a positive effect, can be removed temporarily,Hydraulic cone crusher to find it, according to the installation need timely installation of ball mill. Bearing installation on bearing pressure testing, its value should not be less than 25Mpa, trial of continuous period of not less than 10min, such as the discovery of the complete elimination of leakage should be.Tin ore Production Line Secondary cone crusher font-size: 9pt">The upper cover is installed before, should be first ball mill main bearing cooling water pipe on the water test, test pressure is 0.45 ~ 0.6Mpa, 30min test time, there should be no leakage phenomenon.

Ball mill bearing seat is installed,China sand washers should check the bearing seat of the cooling water hose and the end cover shaft neck and check whether a collision, thermal resistance and shaft neck contact is good. Thermal resistance should be installed in the shaft bearing plate and the bearing side, between each side should be 0.76 ~ 1.5mm space, finally the cleaning ball mill bearing seat of the foreign body, the ball mill bearing shell of useless holes are blocked. Grease filled bearing shell and the shaft neck contact rubber sealing grooves, at the same time test nozzle flow. In ball millmain bearing is installed, should be the bearing base, bearing the relative sliding fit surface is clean.
