Product Introduction

COAL VERTICAL ROLLER MILL_ZK Ball Mill_Rotary Kiln

Coal Vertical Roller Mill (VRM) is an air swept, medium-speed, vertical pulverizer with integral classifier. It pulverizes coal by applying hydraulically-loaded grinding pressure through three grinding roller onto a rotating bed of coal. Grinding pressure can be adjusted to account for variations in coal grindability and desired product fineness.

mill. In principle, the reclaimer must be equipped with speed regulated motors and an integrated belt scale. The trans-port and subsequent proportioning of the reclaimed material and additional raw material is effected by speed regu-lated conveyors. Reclaiming capacity will always match the mill requirement and the reclaimer will operate

Now it is possible to derive the rotor impedance in 4. TARGET COAL MILL OPERATION the new operating point as (11): Z 2 = (1.572 + j 0.4)pu = (50.9 + j12.95)Ω (11) The target is to get coal mill running at 110% of the previous operating speed. Originally, the mill load torque Finally, the motor current at 55Hz driving the coal can be determined
