Canada: Progressive Planet Solutions has successfully produced a new supplementary cementitious material (SCM) called PozDE from diatomaceous earth. The company says that it developed PozDE using calcium bentonite-containing diatomaceous earth from the Red Lake mine in Kamloops, British Colombia. The SCM’s seven-day and 28-day strength activity index (SAI) values are 101% and 120% those of ordinary Portland cement (OPC) respectively, while its water demand is lower at 98%.

Chief operating officer Ian Grant said “It is uncommon to see SCMs exceed the 7-day strength of the control Portland, so we are excited to see better strength while indicating lower water demand."

Germany: Clariant Germany has purchased the first mobile Loesche grinding plant to grind bentonite at its Balikesir facility in Turkey. Clariant required a mobile plant because the site is due to be relocated. The mill is integrated into seven ISO containers, all the electrical connections between the containers are pluggable and no foundations are required for its erection on solid ground. The mill is expected to be commissioned in May 2016.

The vertical roller mill uses a type LM 9.2 D mill, it is designed for grinding industrial minerals and it has a capacity of 1.8t/hour. The Balikesir facility grinds bentonite, which is ground to a fineness of 30% R 0.063. The grinding plant has a power transmission capacity of 45kW. All grinding plant components from the open loop control to the feed bin, the crusher, the mill with classifier, the hot gas generator, the filter, the fan and the pneumatic product transport are placed in containers.

Clariant is a global leader in specialty chemicals. Its headquarters are in Muttenz near Basel in Switzerland.
