China cement mill is composed by feeding part, discharging part, turning part and driving part (reducer, small driving gear, electric motor and electric control). The quill shaft adopts cast steel part and the liner is detachable. The turning gearwheel adopts casting hobbling process and the drum is equipped with wear-resistant liner, which has good wear-resistance. And Have You Studied Main Bearing of Cement Miller?
Main bearing of china cement mills under the quality of the rotary part and the impact of the grinding medium and grinding machine by hollow shaft support on the main bearing, bearing on bearing cover, observation hole (observation of drainage and the workings of the central shaft, bearings), the temperature of the thermometer.Bearing lubrication using both dynamic pressure lubrication and hydrostatic lubrication, dynamic pressure with low oil pump oil, because of the mill speed is low, the formation of dynamic pressure oil film thin, short of liquid friction lubrication, therefore adopt hydrostatic lubrication, cement making machinery have set up the high pressure oil pump for high pressure oil into the oil sac, thicker oil film layer formed by oil pressure.
During normal operation, hydrostatic lubrication work, dynamic pressure lubrication stationary, when occurrence problem of static pressure, dynamic pressure automatic work. General bearing of cement making machinery bush allowed temperature does not exceed 70 ℃, otherwise the tile burning phenomenon occurs, thus cooling methods must be taken.Main inspection area each big oil pump with and without vibration and sound, whether the oil level and oil tank of cement making machinery is normal, without leakage, main bearing, low pressure pump pressure should be above 0.1 MPa, flow rate reached more than 35 l/min, observe whether big tile oil film is in good condition.
In addition, they are professional cone crusher manufactures and dolomite grinding mill suppliers, and mobile mining...
