cze	Simulace výbuchu kávového mlýnu podle směrnice ATEX 137	Článek se zabývá 3D numerickou simulací projevů výbuchu směsi káva-vzduch v kávovém mlýně programem LS-DYNA. Procedura je provedena v souladu se směrnicí ATEX 137. Na základě této analýzy bylo prokázáno, že 3D simulace programem LS-DYNA je velmi silný nástroj pro návrh nového uzávěru mlýna.

eng	SIMULATION OF COFFEE MILL EXPLOSION ACCIDENT UNDER ATEX 137 DIRECTIVE	The paper deals with numerical 3D simulation, through the code LS-DYNA, of the effects caused by coffee powder ? air explosion on a coffee mill cover. The procedure applied follows strongly ATEX directives. From the analysis, it is concluded that the current cover coffee mill design is not appropriate, the cover sealing failure occurs at time around only 17 ms after the explosion when the loading overpressure was only 10% of the maximum overpressure value. On the base of this analysis, it has been concluded that the 3D numerical simulations using LS-DYNA have been a very powerful and useful tool for the design of a new coffee mill covers. However, in more, the analysis performed illustrates quite general approach that can be used successfully for many industrial explosion accidents.
