In fixed hearth kilns, the products are loaded into the kiln manually, mechanized or automatic loader.
Fixed hearth cells kilns loader
The products are placed directly in the kiln or previously stacked on refractory supports.
Ceritherm kilns can come equipped with a swing door – manual or mechanized – or a lifting door. The lifting door is operated by a hydraulic unit or an electric motor depending on door weight. These mechanisms, in accordance with the machine directive, have a “fall stop ” safe system and a secure maintenance position.
The Ceritherm kilns
The Ceritherm kilns have :
