The product is suitable for large and mediumsized cement plants, thermal power plants and mines and other industries vertical vertical mill grinder roll have been exported to Canada, South Korea, Nepal and other countries and Taiwan area. At present, TGC can provide vertical mill wearresistant parts varieties are as follows:
the nozzle ring velocity corresponds to reject rate and pressure drop Running with a high velocity in the nozzle ring gives a high pressure loss, but also a low reject rate. However the lower pressure drop with 45 m/s is to prefer and will both give considerable power savings on the fan and less wear in the mill body Operational problems
Operating data from a coal mill is used to compare the fault detection observerbased method and PCA/PLS models based approach. There are 13 process measurements available representing different temperature, mass flows, pressures, speed etc in the coal mill. ...

NOZZLE RING: The nozzle ring is located between grinding plate and mill housing. The guide channels of the nozzle ring show an oblique arrangement and so create a spiral gas flow. The spiral flow carries the fine material upwards into separating zone. The gas stream enters the mill through an inlet duct which located below the nozzle ring
