For coal mill or coal crusher, the working process is that the raw materials are fed into the coal grinding mill by feeder through feeding machine and hot air goes into the coal grinding mill through the air pipe. With the rotation of mill drum, coal and hot air have heat transfer in the mill and coal is crushed and ground in the mill.
The MPS mill also grinds, dries, calcines, and classifies gypsum without any problem, all in a single machine, for any fineness requested and considering individual requirements. The MPS vertical roller mill built to last, reliable and energyefficient is the optimum solution when it comes to performing several process steps in one unit.
Raw coal from the raw coal bunker is supplied to the Coal Mills by a Raw Coal Feeder. The Coal Mills or pulverizer pulverizes the coal to 200 mesh size. The powdered coal from the coal mills is carried to the boiler in coal pipes by high pressure hot air. The pulverized coal air mixture is burnt in the boiler in the combustion zone.
If the mill is restarted without first removing the hot coal, an explosion can occur when particles are suspended and exposed to the inrushing combustion air. Even in routine mill shutdowns, there is a danger that any residual coal left within the mill will oxidise, and may explode as the mill is restarted.
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. The measurement is not updated, if the variation is less than 1%.
