    Abstract: The present invention relates to a process for the wet production of granules from powdered materials, in particular raw materials for the production of glass. The process of the invention comprises the following successive steps: (i) the powdered materials to be granulated are divided into at least two portions: a first portion and a second portion; (ii) a binder liquid is added to the first portion of powdered materials; (iii) the first mixture thus obtained is agglomerated in the granulator in order to obtain granules (a); (iv) the second portion of powdered materials is added to the granulator; and (v) the new mixture obtained is agglomerated in the granulator in order to obtain granules (b). This sequenced granulation process allows granules to be obtained that have a degree of moisture that assures their stability and their ease of handling eliminating the drying step.

  • Patent number: 8544297
    Abstract: A process and apparatus is provided for enhancing the formation of a uniform population of hollow glass microspheres. A burner head is used which directs incoming glass particles away from the cooler perimeter of the flame cone of the gas burner and distributes the glass particles in a uniform manner throughout the more evenly heated portions of the flame zone. As a result, as the glass particles are softened and expand by a released nucleating gas so as to form a hollow glass microsphere, the resulting hollow glass microspheres have a more uniform size and property distribution as a result of experiencing a more homogenous heat treatment process.

  • Publication number: 20130219963
    Abstract: The production of synthetic quartz glass granules by vitrifying a free-flowing SiO2 granulate from porous granulate particles is time-consuming and expensive. The aim of the invention is to provide a method that allows a continuous and cost-effective production of dense synthetic quartz glass granules on the basis of porous SiO2 granulate. According to the invention, this is achieved by the following method steps: (a) granulating pyrogenically produced silicic acid with the formation of the SiO2 granulate made of porous granulate particles; (b) drying the SiO2 granulate; (c) cleaning the SiO2 granulate by heating in an atmosphere containing halogen in a cleaning furnace; and (d) vitrifying the cleaned SiO2 granulate by sintering in a vitrifying furnace with the formation of quartz glass granules. The drying, cleaning, and vitrifying of the SiO2 granulate are each carried out in a tary tube of a rotary tube furnace, said rotary tube rotating about a central axis.
