<p>A conveyor, e.g. for coal has a conveyor box and a cylindrical housing surrounding this conveyor box. The cavities between conveyor box and housing are sealed by bulkhead(s) in which burst plate(s) are present which seal the cavities dust-tightly, but are destroyed in the case of an explosion so that rapid pressure equalization can occur between the conveyor compartment and the cavities. Preferably there is an aperture with a dust-proof but not pressure tight seal between the cavities and the conveyor box, allowing pressure equalization in normal operation. Advantageously the condition of the burst plate is monitored by suitable means.</p> |
