The design and maintenance of the kiln need to keep the distortion of the structure within acceptable limits. Flexure as the kiln rotates causes reduction in the life of the refractory lining (see below) as well as fatiguing the shell itself. …
A rotary furnace, also called a rotary kiln, is a long tube that is used as a continuous plug flow Another configuration consists of a reverberating design in which material is shaken down the tube.
ROTARY DRYERS, Indirect-Heat Design Capacity based on 10% moisture, wet weight, in material fed to dryer, and 3.26 pounds of moisture evaporated per hour for each cubic foot of the volume of the main cylinder. …
This paper proposes a novel hybrid algorithm for fault diagnosis of rotary kiln based on a binary ant colony (BACO) and support vec- tor machine (SVM). The algorithm can find a subset selection which is attained through the elimination of the features that produce noise or are strictly correlated with other already selected features.
For rotary kilns without a discharge dam, an equation was fist given by Sullivan et al. (1927) to calculate the mean residence time of the solids: (1) MRT = 1.77 · L D · Θ n · β. Accordingly, MRT is proportional to Θ and the size ratio L / D, but inversely proportional to the rotation speed n and the kiln inclination β.
