The coal is taken out from wagons with the help of a machine known as wagon tippler. The coal is the picked and sent to crushers, where it crushed and then to bunkers. From bunkers the coal moves on to mills and is finely grounded to a pulverized form and the fed to the boiler. Then this coal is fed to the boiler and combustion takes place.

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.
