Product Description (1). Introduction of Quick Lime Rotary Kiln, Active Lime Rotary Kiln with Competitive Rotary Kiln Price 1. Rotary kiln refers to the rotating furance pellets,it belongs to the building equipment.2. According to the difference of the processing material,rotary kiln can be divided into cement kiln,metallurgy&chemical kiln and lime kiln.Lime kiln is used for active lime and light burned dolomite roasting in steel works and ferroalloy works.(2) Construction Of Quick Lime Rotary Kiln, Active Lime Rotary Kiln with Competitive Rotary Kiln Price The basic components of a Cement Calcination rotary kiln are the shell, the refractory lining, support tyres and rollers, drive gear and internal heat exchangers. Kiln ShellThis is made from rolled mild steel plate, usually between 15 and 30 mm thick, welded to form a cylinder which may be up to 230 m in length and up to 6 m in diameter. This will be usually situated on an east/west axis to prevent eddy currents. Upper limits on diameter are set by the tendency of the shell to deform under its own weight to an oval cross section, with consequent flexure during rotation. Length is not necessarily limited, but it becomes difficult to cope with changes in length on heating and cooling (typically around 0.1 to 0.5% of the length) if the kiln is very long.BricksThe bricks are determined according to the time-proven performance from every aspect such as temperature distribution in the kiln, wear resistance, and scientific properties (i.e., acidity, neutrality, and reducibility) of the material. As for the joints, dry joints are used normally, while mortar joints are used as needed.Combustion unitGenerally, heavy oil or gas is used for the heat source, which enables either of mono-fuel combustion or multi-fuel combustion according to the combustion conditions. In either case, continuous automatic operation is facilitated through the temperature detection at a set position. The flame monitoring safety device is provided preparing for the contingency.Equipment before/after kilnBefore or apart from the kiln, normally will be a pre-heater.Usually, after the kiln, a rotary cooler is used.(3).
