vertical coal mill explosion prevent in india coal pulverizer explosions ball mill 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.
parameters for coal and petcoke are shown in Table 2. Fine petcoke/coal storage and conveying The fine petcoke/coal is stored in two steel bins mounted on load cells. To ensure smooth extraction, both bins are cone- shaped and manufactured from stainless steel. In addition, they have explosion vents complying with the IS14491 standards.

Explosion vent - Wikipedia
An explosion vent or rupture panel is a safety device to protect equipment or buildings against excessive internal, explosion-incurred pressures, by means of pressure relief. An explosion vent will relieve pressure from the instant its opening (or activation) pressure pstat has been exceeded.
