Besides the treatment of alternative fuels, mineral solids are also reduced in size over several stages before further analysis. As is the case with alternative fuels, sampling, homogenisation and sample division are of key importance here, too.
Treatment of hard and brittle solids:
- Primary size reduction (crushing, coarse grinding)
- Finest comminution (grinding down to analysis fineness)
- Sample merging and homogenisation
- Sample division
e.g. iron oxide, ferrous materials, feldspar, fly ash, rock aggregates, blast furnace slag, lime-stone, clinker, coal, marl, petcoke, pozzolanas, quartz sand, sand, shale, clay and trass
Besides common mills, the following machines are also available for treating solids:
- jaw crusher, disc grinder, coarse grinder, roller crusher
- The following machines are available for homogenisation and division:
- rotating sample divider, sample splitter, drum hoop mixer, tumble mixer, cross separator, vortex mixer
Taking representative samples is essential to obtaining meaningful analysis results and depends on numerous factors, e.g. particle size distribution, sampler and size of the sample. We can assist you starting in the early stages and offer advice on everything from planning sampling to interpreting the measurement results.
