There are easyaccess doors for inspection and maintenance of all of its parts, where roller replacement can occur while still inside the mill. For comprehensive maintenance, the large door is removable for crane access. Our coal mill offers the flexibility of noninert and inert operation, depending on the exploding potential of your coal type.
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%.
