In Egypt, the ATEX Directives will have to be complied with by all coal-using industries very soon. This will be a very interesting process to observe. A cyclone of an indirect firing coal mill system that hardly could have been laid out worse. The cyclone has been installed inside a building, which disallows protection by means of explosion venting. Equipping it with explosion vents has been aborted, as evidenced by the blind covers that have been installed in place of explosion

Coal dust - Wikipedia

08/08/2003  Coal dust is a fine powdered form of coal, which is created by the crushing, grinding, or pulverizing of coal. Because of the brittle nature of coal, coal dust can be created during mining, transportation, or by mechanically handling coal. It is a form of fugitive dust. Grinding coal to dust before combusting it improves the speed and efficiency of burning and makes the coal easier to handle. However, coal

27/09/2018  Egypt’s notorious power black-outs were among a list of grievances when, in 2011, crowds on Cairo’s Tahrir Square forced president Hosni Mubarak from power in one of several revolts known as the Arab Spring. But the new government was unable to lift the output of kilowatts, and outages continued until, in 2014, parliament voted to overturn a ban on importing coal and, two years later, changed the law to allow coal-fired

In case you intend to realise a new coal grinding system independently from the realisation of a new cement line, a similar requirement package will be part of the contract. Even if the coal grinding system now stands in the centre of the discussion with the supplier(s), the discussions will normally not lead to a result that differs from the case described before.

Fire and Explosion Hazards in Cement ... - Dust Safety

Coal is often the main fuel source used to heat the cement kiln. Coal pulverizers are required to grind the coal from the bulk storage size to a smaller particle diameter to use in the kiln. Coal pulverizers significantly reduce the mean particle size of the coal, drastically increasing the fire/explosion hazard risk. This risk is present inside the pulverizing equipment and during transport to the kiln for burning.
