Raw coal is conveyed from the storehouse by a belt conveyer. Then it is lifted to the entrance level of a vertical cylindrical mill by a bucket elevator, and an electromagnet is used to remove iron objects from the raw coal. The raw coal is pulverized in the vertical

mill to produce a coal slurry in the 1-to 5-Vm particle size range. For a number of years, DOE has considered the possible use of microfine coal in water as a substitute for oil in fir ing steam boilers (5) or as an addition to diesel fuel for use in diesel engines

Spill and Accident Procedures: If an accident occurs, report immediately to the lab supervisor (G217-05) or other appropriate staff member. If no one is around, dial 911 on the landline phone near the door of G217-09 to reach the campus police. The lab first aid kit is

Vertical roller mill application Control challenges Among the operational challenges of a vertical roller mill are the fast dynamics of the process. Compared to ball mills with dynamics changing in 15-20 minutes, vertical roller mills have dynamics changing in 2-4
