Shaft Kiln Vertical Shaft Kiln Vertical Kiln AGICO. As one of the main cement equipment, it plays the same role as a cement rotary kiln for cement clinker manufacturing, also composed of preheating zone, calcining zone, and cooling zone, while no matter the production process, investment or cement properties, it is different from the rotary kiln.

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 first rotary kiln was introduced in England to replace the vertical shaft kilns. 1887. Henri Le Chatelier of France established oxide ratios to prepare the proper amount of lime to produce portland cement. He named the components: Alite (tricalcium silicate), Belite (dicalcium silicate), and Celite tetracalcium aluminoferrite).
