Method for controlling and setting desired operating point of e.g. fan-beater mill, during pulverizing e.g. brown coal, involves regulating value representing desired operating point by adjusting mill rotation speed
Method for controlling and setting desired operating point of e.g. fan-beater mill, during pulverizing e.g. brown coal, involves regulating value representing desired operating point by adjusting mill rotation speed
The method involves determining the pressurized conveyed volume flow (12) of pulverized coal in a direction of conveyance behind a grinding space of an injecting mill (2), where the conveyed volume flow is immediately determining based on readings (102), and regulating a value representing a desired operating point by adjusting mill rotation speed. The conveyed volume flow is varied according to the operating point within a permissible range of values and maintained in the permissible range of values. An independent claim is also included for a device for controlling and setting a desired operating point.
