Redesign reject valves, throat rings, classifier vanes, and other internal components as necessary for fuel and application. Perform mill dribble tests to determine minimum throat velocity minimum PA flow. Perform mill response tests to evaluate proper balance of mill primary air/fuel ratio at high load.
The situation is further complicated by the ''mill reject'' streams that reject undesirable material (tramp metal and noncoal bearing rock) from the mill. Generally, the following steps illustrate the path through a VSM: • The raw (coal) feed enters the mill through a central delivery pipe and falls under gravity onto the Grinding Table; •
