Apparatus to amalgamate a paste of vitreous material in the molten state with an additive material in the form of granules, scales, slivers or filaments, made of metal, of other types of glass or other material in order to obtain a vitreous compound. The apparatus comprises containing means (11) to contain the paste of vitreous material, mixing means (15) to convey the vitreous compound downwards, in its molten state, towards rolling means (12) to produce manufactured articles. The mixing means (15) comprise at least a first pair of mixing cylinders (19a, 19b) having the respective axes of rotation (20a, 20b) arranged substantially horizontal, parallel to each other and substantially parallel, or slightly inclined, with respect to the direction in which a rolling force is applied by said rolling means (12).
Apparatus to amalgamate a paste of vitreous material in the molten state with an additive material in the form of granules, scales, slivers or filaments, made of metal, of other types of glass or other material in order to obtain a vitreous compound, said apparatus comprising containing means (11) to contain said paste of vitreous material, mixing means (15) to mix said vitreous compound while it is conveyed, in its molten state, towards rolling means (12) to roll said vitreous compound for the subsequent production of manufactured articles, characterized in that said mixing means (15) comprise at least a first pair of mixing cylinders (19a, 19b) having the respective axes of rotation (20a, 20b) arranged substantially horizontal, parallel to each other and substantially parallel, or slightly inclined, with respect to the direction in which a rolling force is applied by said rolling means (12).
Apparatus as in any claim hereinbefore, characterized in that inclusion means (22) are arranged between said containing means (11) and said mixing means (15) in order to insert inside said paste of vitreous material at least an additive material in the form of granules, scales, slivers or filaments.
Apparatus as in any claim hereinbefore, characterized in that each of said mixing cylinders (16a, 16b;
Apparatus as in any claim hereinbefore, characterized in that heating means (41) to heat said vitreous compound are arranged at least upstream of said rolling means (12).
Apparatus as in any claim hereinbefore, characterized in that at least part of said mixing cylinders (16a, 16b;
Method to obtain a vitreous compound starting from a paste of vitreous material in the molten state and comprising a step of inserting an additive material in the form of granules, scales, slivers or filaments into said paste of vitreous material flowing from a containing element (11) towards rolling means (12) to roll said vitreous compound for the subsequent production of manufactured articles, characterized in that downstream of said step of inserting said additive material there is at least a first mixing step to mix, by means of crushing, the compound of vitreous material and additive material, in a direction substantially orthogonal, or very inclined, with respect to the direction in which a rolling force is applied by said rolling means (12).
Method as in any claim from 13 to 15 inclusive, characterized in that water or other cooling liquid is made to flow in each of said mixing cylinders (16a, 16b;
Vitreous compound obtained with an apparatus according to any one of the claims from 1 to 11 inclusive, or by means of the method according to any one of the claims from 12 to 16 inclusive, and comprising a paste of vitreous material amalgamated with non-vitreous additive material in the form of granules, scales, slivers and/or filaments.
