Before the start of vertical roller mill, you should check all access doors are closed tightly, to adjust the fan and the spindle, the exhaust valve should be in the fully open position. After starting the engine, should immediately charge (you should add a small grain size, coupled with the normal material) and then open the air valve, the inlet not to spray under the premise should try to close the exhaust valve. Then adjust finished product fineness. With a jaw crusher and hoist series gap should be checked before starting the jaw crusher is consistent with the particle size of the feeding material, adjust the vertical roller mill speed should be approximate analysis for finished product size. Finally, according to the following order to boot.
Open bucket hoist
On the jaw crusher
To have the material hopper, start the analysis machine
The blower is started (empty load starting, to normal operation after loading)
Starting the engine, at the start of the host instant start of electromagnetic vibration feeder. At this grinding work is started.
The sequence of vertical roller mill operations that are as follows: the simple "start" hoist - crusher - Analysis - Fan - Host - feeder.
Stop vertical roller mill should be in the following order off the machine:
Turn off the feeder stop feeding
For a minute after the cessation of the host
The material remaining after blowing off the blower
Finally, analysis of closing machine
The shutdown sequence is: feeder - Host - blower analysis machine
Note:
Hoist transport materials to hopper must finally, first stop the crusher and then cease to ascend, this should be the storage volume change.
vertical roller Milling machine in normal operation is allowed to refuel, to ensure production safety, milling machine in any part of the occurrence of abnormal noise, or load increases suddenly, should immediately stop check, troubleshooting, so as to avoid the occurrence of major accidents. Continue to boot must be mill take out the residual material, not just the boot when the current is too large, the start.
