Abstract
A method of producing a glass briquette in which reclaimed glass fines are mixed with a binder material to create a mixture. The mixture is subsequently compressed in a chamber to form a briquette having the shape of the interior of the chamber. The reclaimed glass includes glass fines of a size of smaller than 10 mm. The method is performed without melting the glass fines such that the resulting briquette contains the discrete glass fines held in the binder and may be used as a furnace ingredient for later glass product production. The glass briquette may contain other batch ingredients required in the production of glass.
Claims19
A method of producing glass briquettes, comprising the steps:
- a) providing reclaimed glass as glass fines of a size of smaller than 10 mm
- b) spraying a binder material comprising a lignosulphate and/or sodium silicate onto the glass fines and mixing the binder material and reclaimed glass to create a mixture having 2-5% by weight of the binder material;
- and subsequently
- c) compressing said mixture in a chamber to form briquettes having the shape of the interior of the chamber and capable of withstanding a drop test from a height of 1 m;
- wherein steps b) and c) are performed at a temperature below the melting point of the glass fines, such that the glass fines remain present as discrete, solid particulate material contained with the binder of the mixture in the formed briquettes.
A glass briquette, comprising:
- a compressed mixture of reclaimed glass fines of a size of smaller than 10 mm and having 2-5% by weight of a binder material comprising a lignosulphate and/or sodium silicate, wherein the reclaimed glass comprises glass fines are present as discrete, solid particulate material contained with the binder of the compressed mixture and the glass briquette is capable of withstanding a drop test from a height of 1 m.
A method of producing glass briquettes, comprising the steps:
- a) mixing reclaimed glass comprising glass fines of a size of smaller than 10 mm with silicon dioxide, sodium carbonate and calcium oxide;
- b) spraying a binder material comprising a lignosulphate and/or sodium silicate onto the product of a) and mixing the product of a) with the binder material to create a mixture having 2-5% by weight of the binder material;
- and subsequently
- c) compressing said mixture in a chamber to form briquettes having the shape of the interior of the chamber and being capable of withstanding a drop test from a height of 1 m;
- and
- wherein the steps are performed at a temperature below 500° C., such that the glass fines remain present as discrete, solid particulate material contained within the binder of the mixture in the formed briquettes.
