Laboratory Roller Kiln LRK-1230/140-1220

Laboratory roller kiln permits simulation of any firing cycle, faithfully reproduing the required operating conditions. The thermal gradient of firing curve can be readily controlled at any point of the cycle and the optimum gradient for the product being examined. Outside structure steel plate coated with epoxy powder paint. Internal structure insulating refractory ceramic materials for those parts exposed to the fire; ceramic fibres for the insulating parts.
