The explosibility of some industrial dusts in a cyolone plant has been investigated. The dusts were dispersed in the turbulent air stream and ignited with a propane flame. All the dusts which propagated explosions in the plant were in explosibility Class I. Manioc, a marginal Class I dust, and calcium citrate, a Class II dust, did not explode. Preliminary information has been obtained on the size of vents to safely relieve explosion pressures in the cyclone itself.
