An apparatus for automatically wetting and mixing glass batch immediately prior to its introduction into a glass melting furnace. This apparatus is an axillary extension of a typical glass furnace charger hopper and provides for complete glass batch wetting and mixing immediately adjacent the glass melting furnace so as to minimize the possibility of batch "dryout" and similarly thereby minimize atmospheric dust pollution and other associated problems. Mixing action is continuous and the apparatus is arranged such that a fluid, normally water, is added to and mixed with the batch responsive to charger operation. The apparatus is structured in such fashion to emphasize mixing rather than material conveyance, thus reducing wear upon the structural elements while at the same time providing complete and uniform wetting of the batch within same.
A combined glass furnace batch charging and mixing apparatus and comprising an integral hopper and receptacle, said receptacle being positioned atop said hopper and having separate top inlet and bottom outlet openings disposed one above the other, rotatably mounted mixing means positioned within said receptacle and separate feeding means positioned within said hopper, driving means for each said mixing means and feeding means, and a fluid delivery system including fluid delivery means positioned for simultaneous wetting and feeding such that batch upon entry to the receptacle is wetted therefrom, said fluid system including control means that responds in conjunction with movement of said feeding means to discharge fluid through the delivery means and which upon cessation of feeding means movement terminates said flow of fluid.
