Measurement Tools For The Cement Industry

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.

The cement kiln

Wet process kilns. The original rotary cement kilns were called 'wet process' kilns. In their basic form they were relatively simple compared with modern developments. The raw meal was supplied at ambient temperature in the form of a slurry. A wet process kiln may be up to 200m long and 6m in diameter.
