ATOX coal mill - FLSmidth
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 shock-resistant and equipped with a number of explo-sion relief valves. From the raw coal silo, the feed is extracted and conveyed in enclosed equipment. Both the mill and ...

Pulverizer - Wikipedia
The grinding force for coal pulverization is applied by a loading frame. This frame is connected by vertical tension rods to three hydraulic cylinders secured to the mill foundation. All forces used in the pulverizing process are transmitted to the foundation via the gear reducer and loading elements. The pendulum movement of the roller wheels provides a freedom for wheels to move in a radial ...
