What is an explosive atmosphere? An explosive atmosphere is an accumulation of gas, mist, dust or vapour, mixed with air, which has the potential to catch fire or explode. An explosive atmosphere does not always result in an explosion, but if it caught fire, the flames would quickly travel through it.
Zone 21 (ATEX 1999/92/EC) definition. What is a Zone 21 hazardous area? A Zone 21 area is classified as a place in which an explosive atmosphere consisting of a mixture with air or flammable substances in the form of powder or dust is likely to occur in normal operation occasionally.
The ATEX directive consists of two EU directives describing what equipment and work space is allowed in an environment with an explosive atmosphere. ATEX derives its name from the French title of the 94/9/EC directive: Appareils destinés à être utilisés en ATmosphères EXplosives
Technical Article: Understanding ATEX Milling Introduction to ATEX. Past legislation to control explosive atmospheres has only been concerned with electrical equipment. The current ATEX directives now include hazards from mechanical sources, such as mills. A seized bearing or mechanical failure causing excessive heat generation is as likely a ...
Fit silos or bins with explosion relief and vent to an unoccupied place of safety, preferably outside the building. Ensure that the venting system is designed to an acceptable standard. Vent openings should be unrestricted to allow the free venting of an explosion. Protective systems such as explosion relief panels need to be ATEX certified.
ATEX Conical Mill for Use in Explosive Atmospheres Why an ATEX Conical Mill is Needed "An explosive atmosphere is defined as a mixture of dangerous substances with air, under atmospheric conditions, in the form of gases, vapours, mist or dust in which, after ignition has occurred, combustion spreads to the entire unburned mixture." 1 Hence, the presence of gas or dust in certain ...

varnishes, solvents and dust which when mixed with air could cause an explosive atmosphere ( dust from milling and sanding operations). Flammable substances may be found, in varying quantities, in most workplaces. An explosive atmosphere means a mixture with air, under atmospheric conditions, of
Mining of coal leads to coal dust, and flour mills likewise have large amounts of flour dust as a result of milling. A gigantic explosion of flour dust destroyed a mill in Minnesota on May 2, 1878, killing 14 workers at the Washburn A Mill and another four in adjacent buildings.
In Europe, similar regulations have been enforced since the 90s and take the name ATEX (Atmosphere Explosive). A dust explosion analysis is also required. ... On the other hand, for a mill reaching 2040 m/s in tip speed, the risk will be high that sparks happen in case of malfunction or presence of foreign bodies. 4. Calculate the risk
Having left the mill at the top, the final product continues with the gas to the filter or cyclone, where it is collected. Tailormade layout The layout of your coal grinding system must take into account the available heat sources for drying the raw coal as well as the fire and explosion hazards of coal and coal dust. The entire grinding
