<p>Clayware pipes to be fired are conveyed longitudinally through the kiln on a series of driven rollers (12) extending transversely of the kiln, there being an induced draught passing through the kiln from the pipe outlet end to an extractor duct near its inlet end. The pipes are located by spacers 14 on the rollers. The spacers 14 may be angled or mutually offset on adjacent rollers to cause the pipes to rotate. Alternatively the axis of rotation of the rollers can be shown to make the pipes rotate. <IMAGE></p> |
