The New Revimac Coloring System for glass conditioning Forehearths, enables the feeding, melting and mixing of the colorant before the final cooling and conditioning of glass.
The installation of such a system determines an additional length of the forehearth from 3 up to 6 meters approximately.
It is basically subdivided into the following zones :
Pre-heating zone: its function is to maintain a regular glass temperature that enables the proper melting of the color concentrate. The needed temperature is reached by means of a set of double-stack burners and controlled typically through an optical pyrometer.
Melt zone: this must be long enough to allow sufficient time for the colorant to melt and to exhaust the combustion gases on the glass surface before stirring.
Stirrers zone: it is required to ensure proper mixing of the colored glass.
