Drying sand by hot air

Natural gas burner is used to burn the natural gas, and the hot air furnace is used to supply the burning chamber. Finally under the function of induced draft fan, the hot flue gas goes into sand dryer machine, then heat and dry the wet sand, and evaporate the water into vapor, finally gets the dry sand as need. After being dried by sand drying

    The Continuous Fluid-Bed Dryer/Cooler In Sand

    Drying occurs because of the direct contact between the damp material and the hot air blown through it. The air velocity is adjusted to keep the moving layer of material fluidized. The same mechanism applies to the cooling part of the process, except that the air used is either ambient or conditioned (ie cooled)

    Hot air furnace supply the hot air for the sand dryer. Inside the sand dryer's cylinder, there are many flights, and these flights mix the wet sand and hot air sufficiently. The humidity in the wet sand is heated and evaporated into water vapour. At the end of the sand drying plant, there is one high pressure draft fan. Under the function of

    Oct 19, 2020 Fluid bed technology is used for cooling, heating and drying of bulk solids materials. Fluid bed heat exchange takes place by passing a gas (most commonly air) through a perforated distributor plate which then flows through a layer (bed) of solids. The air performs two functions. First, the air flows through the bed of solids at a velocity
