Abstract
Essentially dry hygroscopic dust recovered from the waste gas of a glass melting furnace is agglomerated with coarser particles of silica sand, calcium carbonate or dolomite having a moisture content of 5-20%, by weight, by intimately mixing the dust and coarser particles, and tumbling the mixture until particles of the dust are attached to the moisture-containing coarser particles.
Claims5
A method of agglomerating hygroscopic dust and a water-insoluble material, comprising
- a. placing within a sealable bag hygroscopic dust recovered from waste gas of a glass melting furnace and water-insoluble particulates selected from the group consisting of silica sand, calcium carbonate and dolomite, said particulates being coarser particles than said dust and having a moisture content of 5-20% by weight, an amount to adhere said dust particles to said coarser particles in forming agglomerates,
- b. sealing said bag,
- c. placing said sealed bag within a movable container,
- d. moving said container to tumble said bag therein to intimately mix and cause said dust particles to adhere to the surfaces of said particulates and form agglomerates thereby, and
- e. terminating the movement of said container, removing said bag therefrom, and recovering said formed agglomerates from said bag.
