Explosion Protection For the Dairy Industry White Paper

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. Here the risk exists that tramp metal can get trapped in the grinding media.
