MECHANICAL CONDITION MONITORING ON ROTARY KILNS
Kiln Shell Laser Kiln Shell Laser The Kiln Shell Laser is a measurement tool, which measures the deformations (roundness, straightness, eccentricity) in shells of rotary kiln and dryer during operation. It measures continuously the distance to the shell and records the deviations. The tool is placed in various positions along the kiln.
A Preliminary Control System on a Barium Sulphide .
Rotary kiln processes are strongly coupled multivariable nonlinear systems with large lag. A barium sulphide rotary kiln process is still under manual control because of the lack of analysis instrument, so that the burning status cannot be maintained stable and the product quality is hard to be kept consistent. To deal with this problem, this paper proposes a preliminary control strategy based ...
