Rotary Kiln an overview ScienceDirect Topics

The main components of a rotary kiln are an inclined cylindrical, refractory-lined reaction shaft equipped to rotate over rollers and a burner. Process heat is generated by burning fine coke or coal contained in the charge and by the exothermic heat of the PbO reduction by CO. This process produces molten lead and a slag with 3–5% Pb.

WE’RE ON FIRE FOR THE MOST EFFICIENT LIME KILNS.

2017-6-1 · The PFR kiln from Maerz is ideal for the production of soft-burnt lime. The lime is calcined in a parallel flow. The feedstock and the combustion gases move in the same direction from top to bottom. The energy needed for the calcination is supplied at the begin- ning of the calcination process.
