Abstract
A method and apparatus is disclosed for the formation of lumps or pellets of mixtures of raw materials for glass. Soda and water are added to a mixture of the raw materials in a mixing container. The resulting mixture is at least partially heated for vaporization of the water and the mixture is compressed in a roller press. Pellets or lumps result which are fed to a heat exchanger for pre-heating prior to introduction into a melting furnace. Exhaust gases from a furnace are fed to the heat exchanger and also to the mixing container and a supply container for the roller press.
