The roller kiln and the prefabricated oven with lighted carriages represent, under precise design conditions, a timely and integrated response to the request of a heat treatment system that allows rapid firing of sanitary materials. The low thermal inertia represented by the prefabricated modular structure, obtained with the use of light refractory bricks in the first face and ceramic fibers in the second, represents a necessary condition to give elasticity and manageability to the thermal machine.
For the hypothesised conditions to be realized, however, the plant installed on the machine and the control and regulation devices have been designed in a manner consistent with the required elasticity and manageability.

Once these conditions have been met, the choice between a roller kiln and a trolley oven will be based essentially on the production potential required, on the variety of the planned type or, more generally, on the desired setting of the production line to be created, which is the main matter of discussion. It should always be remembered that as the dough and the enamel are to be designed according to the thermal cycle that is to be realized, so too the oven to be used must be designed according to the entire production line. Intensive high speed burners are installed on the ovens. The burner types are selected and alternated according to the thermotechnical characteristics of the various zones and the particular functions that are assigned to them in the operating economy of the kiln. Each burner is equipped with automatic ignition and flame control.
