Definitions
- the invention relates to a method for the production of foam glass granules with the features specified in the preamble of claim 1 features.
- the glass batch is placed in a container designed as agitator tank in which the glass batch is stirred for a stirring time of 50 to 80 minutes for at least partial digestion of the glass components.
- the glass batch is introduced via a metering pump into a continuous granulating mixer, in which metered addition of additional glass powder is added in such a way that the moisture content of the glass batch drops to about 18 to 18.5%.
- Granulated green bodies form in the granulating mixer and are subsequently dried and foamed, for example, in a rotary kiln to give foam glass granulate particles at temperatures of around 800 ° C.
- a disadvantage of the known process is the fact that a high expenditure of energy is required for the heating of the water to form the aqueous glass binder slurry for this so-called "hot digestion.”
- hot digestion there is a general desire to use the highest possible foam glass granule particles To be able to produce strength in order to make it as pressure resistant and mechanically stable in terms of universal applicability in a variety of products.
- the invention is based on the object to improve the known method for foam glass granulate production so that with lower energy use granules are obtained with higher strength.
- the glass batch is sent via a metering pump in a continuous granulation, is mixed into the further glass powder to form granules green bodies.
- additional green grain having a particle size of preferably 0.25 to 0.5 mm is added as a granule nucleating agent.
- the mass fraction is about 4 to 8% based on the total mass of glass batch and dosed glass flour.
- the granulated green bodies thus produced are passed over a Granulêtl- ler, where a subsequent granulation on the granule green body is carried out to a higher average grain size. Furthermore, the granule green bodies are dried in a granulating dryer to a residual moisture content of 0.1% and classified by screening in different granule particle sizes before foaming.
- Typical particle size classes are, for example, the following diameter ranges: 0.25 to 0.5 mm,
- the corresponding granules are then foamed in a conventional manner in a rotary kiln at a temperature of about 790 ° C.
