Calcium sulphosilicate in lime-kiln wall coating
Summary Green calcium sulphosilicate layers were formed in lime-larnite-calcite wall coating in a lime kiln at Rivervale, Western Australia. The compound formed in the kiln flame area by the combination of siliceous lime sand feed with sulphur xide from the sulphurous oil fuel. The calcium sulphosilicate is orthorhombic with a 10·183, b 15·408, c 6·825 Å, space group Pcmn.

Rotary kilns for cement plants
In the ROTAX-2 kiln, an electro-mechanical direct drive on the support rollers replaces the electro-mechanical gear rim pinion drive used on the traditional 3-base kiln. The friction between the roller and the kiln tyre is sufficient to ensure the rotation of the kiln. No lubrication is needed for the drive station.
