ZGM113G coal mill roller device

2018 - ZGM113G coal mill roller device 08 - 02 ( Xd operation department) ZGM113G roller device by roller mill, roller, roller, roller core, bearing, oil seal, etc. Roller in the mill and crushing, tilt 15 & deg; By crushing positioning. Used in the process of roll ring is unilateral wear, wear after certain depth can be turn to use, to make full use of wear resistant material. Roller running under high temperature, inside cavity of the oil temperature is higher, Up to 110 ℃) To ensure good lubrication bearing, roller in filled with high viscosity, high viscosity index, high temperature stability, good synthetic hydrocarbon SHG high temperature bearing, gear oil, each roller oiling 29 liters. By two oil seal oil seal: the first oil seal external environment, the second internal lubricating oil, oil seal between the two oil seal fill grease has higher heat resistance, used to lubricate the first oil seal lip. Roller with the size of two kinds of bearings, cylindrical roller bearing is bearing, small bearings is a double row centripetal spherical roller bearings, two bearing roller under radial force and axial force. The role of the roller frame is pass through the hinge axis loading force to roller. It through roller seal duct connected to the seal air system, seal the wind through the roller frame inner cavity flow to the grinding roller between air sealing ring, oil seal external and roller in the cleaning of loop seal, prevent damage of pulverized coal in the oil seal, and also has the effect of reducing the grinding temperature. At the end of roller frame of the roller is equipped with breathing apparatus. It makes the oil seal and internal wind cavity are interlinked, eliminate the negative effects of different temperature and pressure, to ensure the normal pressure of oil cavity and good environment. On the roll shaft is equipped with the oil level measurement probe hole, screw the plug after use.
