Lime kiln live feed

Nov 28, 2016 Kiln Feed and Feeders. High quality lime can be produced at a uniform rate only if the kiln is fed at a constant rate with lime sludge of constant composition. In some cases the feed to the kiln consists of a pumpable sludge containing 55 to 65% water. However, in most installations a drum filter or a centrifuge is installed just ahead of the

    Specifically in the lime kiln, wet lime mud enters at the feed end and is transported towards the discharge end due to the rotation and inclination of the kiln. On its way through the kiln, lime mud is heated by hot flue gases that move counter-current compared to the solids. Heat is supplied from a burner located at the discharge end

    The conventional rotary lime kiln has a length-to-diameter ( L / D) ratio in the 30–40 range with lengths of 75–500 ft (22.7–152.5 m) and diameter of 4–11 ft (1.2–3.3 m). Lime kilns are usually inclined at about 3 –5 slope with material charged at the elevated end and discharging at the lower end

    Lime kiln - Wikipedia

    A lime kiln is a kiln used for the calcination of limestone (calcium carbonate) to produce the form of lime called quicklime (calcium oxide).The chemical equation for this reaction is . CaCO 3 + heat → CaO + CO 2. This reaction can take place at anywhere above 840 C (1544 F), but is generally considered to occur at 900 C(1655 F) (at which temperature the partial pressure of CO 2 is 1

    The purpose of this thesis is to create a model of the lime kiln that performs mass- and energy balances over the process. This model is to be integrated in the WinGEMS software that is used to simulate mill systems in the pulping industry. There is an existing lime kiln block in WinGEMS but since has proven inadequate and in need of replacement
