Coal Mill
The analysis of individual mill design and operation is complex; so, for simplicity we will consider a typical mill layout for one mill type only. As VSMs have come to represent the bulk of the power station mill fleet, the explanation of mill operations will be based on this mill type. Figure 13.2 illustrates the typical key components of a VSM.

Silo/Filter Probe System for coal mill
Silo/filter probes for your coal mill system. Highly combustible coal dust poses a serious hazard. CO builds up in coal-filled silos and in cyclones or bag houses that are not being used, while imprecise O2 levels in inert coal mills can also present a significant danger. In either situation, self-ignition is a real possibility.
