  • What is a Rotary Tube Furnace?

    By definition, a rotary tube furnace is a heat-treating circular furnace, which rotates during heat-treatment. Samples are transported through the furnace in a circular path as they are heated. Rotary tube furnaces generally burn pulverized, solid, gaseous or liquid fuel into its working section, and then the heating gases created flow towards the sample. These furnaces feature a metal drum lined ...

  • Enhancement of struvite pellets crystallization in a full-scale plant using an industrial grade magnesium product

    A full-scale struvite crystallization system was operated for the treatment of the centrate obtained from the sludge anaerobic digester in a municipal wastewater treatment plant. Additionally, the feasibility of an industrial grade Mg(OH)2 as a cheap magnesium and alkali source was also investigated. The struvite crystallization plant was operated for two different periods: period I, in which ...

  • Iron Ore Pelletizing Plants - Case Study

    Changing the iron ore processing chain The iron ore being mined globally can approximately be divided equally into boulders and fines. For further processing boulders have to be sized to 10-30 mm for blast furnaces and 6-18 mm for sponge iron plants. Iron ore in a finely ground state is not easily transported or readily processed .The iron ore pelletizing process agglomerates the fine ...

  • Modelling particle growth of calcium carbonate in a pilot-scale pellet fluidized bed reactor

    Pellet fluidized bed reactors have been widely used to soften water. Reports from laboratory-scale research on the particle growth kinetics of calcium carbonate in pellet reactors have been put forward. However, the reports have not been comprehensive as they only consider the influence of supersaturation on the calcium carbonate growth process. The influence of three factors, namely, the ...

  • Filtration media: Shapes and manufacturing processes

    The shape of the filtration media and the production process directly affect the absorption capacity of the granulate and consequently the efficiency of filtration. Granules in the shape of a pellet (cylinder) do not facilitate such a high degree of compaction as spherical granules, so that the passage of the air flow becomes easier, ...
