were proposed to mitigate various negative phenomena experienced in the operations of vertical kilns. Keywords : Vertical shaft kiln, Operation, strategy, investment, Burner, Firing, Profile. 1.0 Introduction The vertical shaft lime kilns have been shown to posses a lot of potentials in the lime industry ( Okonkwo etal 1991).
One of these parameters may restrict the application in the refractory industry, especially if top quality refractory bricks are to be produced. It is almost impossible to correct these effects with modified kiln operation. The vertical shaft kiln used for the sintering of dolomite uses calcined dolomite briquettes as the feed material.
Rotary lime kilns are large steel tubes that are lined on the inside with refractory bricks. They are slightly inclined from the horizontal and are slowly rotated on a set of riding rings. Lime mud is introduced at the uphill, feed end and slowly makes its way to the discharge end due to the inclination and rotation. A burner is installed at the downhill or discharge …
