I would think the design considerations would be similar, with the main exception that grain dust explosions can yield secondary explosions when loose material is shaken loose by the primary explosion. Technical references are available for velocity/pressure.
It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.
You might poke around Factory Mutual's public guide, Prevention and Mitigation of Combustible Dust Explosion and Fire, FM 7-76, April 2013, available here,
