Abstract
Abstract Method of forming granules from meltable mixtures containing sand, aqueous sodium hydroxide and quicklime. The components are fed to a granulating mixer and are mixed in the presence of heat until compact granules have been obtained. The mixture to be fed to the granulating mixer may also contain soda ash and limestone.

Claim 1
Independent Claim
29 words
aqueous sodium hydroxide solution of about 50 percent concentration and in an amount sufficient to provide a quantity of water to enable the formation of granules by agglomeration; and
Claim 2
Dependent Claim
29 words
aqueous sodium hydroxide solution of about 50 percent concentration and in an amount sufficient to provide a quantity of water to enable the formation of granules by agglomeration; and
Claim 3
Dependent Claim
23 words
A method as claimed in claim 1, wherein the water content of the mixture of (a) is between about 5 - 8 percent.
Claim 4
Dependent Claim
29 words
aqueous sodium hydroxide solution of about 50 percent concentration and in an amount sufficient to provide a quantity of water to enable the formation of granules by agglomeration; and
Claim 5
Independent Claim
17 words
A method of forming granules from a glass-producing mixture comprising: a. preparing a mixture consisting essentially of
Claim 6
Dependent Claim
50 words
quicklime and limestone; b. feeding said mixture into the mixing zone of a rotating mixing granulator and rotating the mixture in said mixing zone to form granules, whereby the water in said aqueous sodium hydroxide solution reacts with said quicklime in the forming of said granules in said mixing granulator.
Claim 7
Dependent Claim
48 words
quicklime; b. feeding said mixture into the mixing zone of a rotating mixing granulator and rotating the mixture in said mixing zone to form granules, whereby the water in said aqueous sodium hydroxide solution reacts with said quicklime in the forming of said granules in said mixing granulator.
Claim 8
Dependent Claim
53 words
quicklime; b. feeding said mixture into the mixing zone of a rotating mixing granulator anD rotating the mixture in said mixing zone in the presence of heat to form granules, whereby the water in said aqueous sodium hydroxide solution reacts with said quicklime in the forming of said granules in said mixing granulator.
Claim 9
Independent Claim
133 words
A method of forming granules from a glass-producing mixture comprising: a. feeding a mixture of heated sand and quicklime into the mixing zone of a rotating mixing granulator and rotating said mixture in said mixing zone at a first rotational speed; b. adding aqueous sodium hydroxide solution of about 50 percent concentration to the mixing zone, said aqueous sodium hydroxide solution being added in an amount sufficient to provide a quantity of water to enable the formation of granules by agglomeration; and c. rotating the resulting mixture in said mixing zone at a second rotational speed to form granules, said first rotational speed being greater than said second rotational speed, whereby the water in said aqueous sodium hydroxide solution reacts with said quicklime in the forming of said granules in said mixing zone.
Claim 10
Dependent Claim
19 words
The method of claim 4, wherein the mixture of (a) also contains an amount of limestone as calcium-containing component.
Claim 11
Independent Claim
17 words
A method of forming granules from a glass-producing mixture comprising: a. preparing a mixture consisting essentially of
