The vast majority of coal mill designs are based upon a 50 to 55 HGI design point. However, grindability is a complex issue and such factors as coal moisture content, required fineness (high volatile coals can require a coarser grind) along with the milling and burner systems are all factors in assessing coal grindability. Generally, a value of ...

Tailormade layout The layout of your coal grinding system must take into account the available heat sources for drying the raw coal as well as the fire and explosion hazards of coal and coal dust. The entire grinding plant must therefore be shockresistant and equipped with a number of explosion relief valves. From the raw coal silo, the feed is

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 cylindrical mill, and the pulverized coal is lifted to a powder separator by

VG: At best, coal mill safety is not well understood and, at worst, it is ignored. When it comes to coal mill systems, most cement plant operators just presume that the supplier of the equipment knows all of the standards and rules and is capable of making a system that conforms to these and is therefore safe. However, this is not the case.
