Ceramic fibre production line
A complete ceramic fibre production line consists in several machines that process the material, from melting to packaging. The “hot” part is located at the beginning of the line where the machine melts raw materials (silica, alumina and feldspar) and transforms them into fibre. The polymerisation and material processing stages follow, where the product takes on its final shape (panels and mattresses both needled). The packaging system is located at the end of the line and consists in machines that package the product and prepare it for warehousing or shipment.
The indicative production capacity of a ceramic fibre line can vary from 200 – 500 kg/h with electric melter.
Product specifications can vary according to the customer’s requirements. The working width of a production line is 1220 mm.
Fibre production
Ceramic fibre is obtained by melting and transforming sandy materials silico-aluminous. A complete ceramic fibre system consists in a machine assembly, which carries out the transformation process. The first stage of the process consists in the storage and melting of the sandy materials. The machines that make up this part of the line generally include: raw material storage, mixing and feeding system; a melting system and fibre forming. The latter transforms the melted material into fibre by means of a centrifuge.
Material formation
This stage is fundamental to achieve good quality end products.
The fibre feeding/distribution system, the needling machine and the annealing oven are the most important machines in this part of the line.
Smokes and dust filtration systems
To safeguard the environment, Gamma Meccanica has always given priority to developing and providing its lines with efficient systems to filter and treat the gases and residues which can be produced during the transformation process.
Processes and final product
After the annealing process, the ceramic fibre felt is ready to be transformed into panels or rolls. On leaving the annealing oven, the material is trimmed. The trimmings are automatically recovered and returned to the production process.
Packaging systems
The production process ends with the material packaging phase: Gamma Meccanica proposes several solutions to pack the end product in order to satisfy different market requirements.
