Its processing capabilities and application flexibility make the machine the ultimate tracked mobile solution for the processing and separation of recycling materials such as incineration slag, shredder light and heavy fraction, scrap metal, electronic scrap, C&D, C&I, bulky waste, compost, plastic fractions, biomass, topsoil, ore and aggregates.
The contents of light naphtha, medium fraction and heavy fraction of the shale oil derived in 40 min are 11.
Schideman noted that the heavy fraction could potentially be used in asphalt-like products.
The biocatalytically oxidized fuel is then distilled in order to eliminate the heavy fraction which contains most of oxidized organosulfur compounds.
The nitrogen content in this soil fraction (density [is less than] 2 g/mL) generally decreases with cropping more than the nitrogen content in the soil heavy fraction, which reduces the ability of the soil to mineralise nitrogen (Dalal and Mayer 1987a, 1987b).
Laminar flow directs the heavy fraction of flake out the bottom and the light fraction out the top, separating any plastics with a difference in density over 0.
The gangue minerals are essentially quartz, carbonate and graphite which readily float while the copper bearing minerals are essentially chalcopyrite and chalcocite which readily report to the heavy fraction.
