In kilns with moveable plate -kiln cars, products are loaded outside the kiln on the moving plate – kiln car – using a manual, mechanized or automatic charger.
The loaded moving kiln car is then positioned in the kiln. This kiln design enable loading/unloading operations from one kiln car whilst the firing of another and/or give an increased accessibility to the load. The products are either placed directly in the kiln, or previously stacked on refractory structures for porcelain kilns.
Moving hearth cell kiln with low thermal inertia
Ceritherm moving hearth kilns can be equipped with a manual or mechanized swing door, a lifting door or a door mounted on kiln car. The lifting door is operated by a hydraulic unit or an electric motor, depending on the weight of the door. These mechanisms, in accordance with the machine directive, have a « fall stop » safe system and a secure maintenance position.
