Rotary Kiln

Rotary Kiln

Rotary kiln is also known as lime rotary kiln.

Product specification:Φ2.5×40m-Φ6.0×95m

Production capacity:168-10000t/h

Rotation speed:0.1–5 r/min

Applied materials: roasting cement clinker in the industries of metallurgy, refractory matter and chemical plant.

in the lime kiln the reaction caco3 gives cao and co2 goes to completion because of

Thisreactionis irreversible in open system. Duringthe reaction CO2gasgoesout and the reversereactionis impossible. But if thisreactionis carried out in the closed system (sealed flask, tube etc.), it is reversible,because CO2gas can no We are a professional mining machinery manufacturer, the main equipment including: jaw crusher, cone crusher and other sandstone equipment;Ball mill, flotation machine, concentrator and other beneficiation equipment; Powder Grinding Plant, rotary dryer, you can click the button to consult us.

    Sothe reaction goesquickly. As they get used up, the forwardreactionslows down. Since this is a reversiblereaction, the products now have enough to start colliding with each other and forming the old reactants And so itgoes, back and forth until the rate of the forward and backwardreactionare the same. This is then called dynamic

    Nov 01, 2012· Most researchers prepareCaOeither via CaCl2 -> Ca(OH)2 ->CaOway, orCaCO3->CaO. And of course you can't allowCO2to pass into the device whereCaOis being prepared,because CO2will ruin everything. For this reason you can't prepareCaOusing an open flame of propane torch: C3H8 + 5 O2 => 3CO2+ 4 H2O
