Explosion protection for coal grinding plants. What

2020-12-11  Most explosions in coal mill plants have their initial ignition location within the mill chamber. This is because the mill chamber is the section of the plant in which the conditions for the ignition of air dispersed fuel are most favourable, as well as the risk that tramp metal gets trapped in the grinding media. Also, grinding causes impact ...
