It is possible that they might be referring to a type of calcium ...
Most polyolefin fabricators will use calcium carbonate via masterbatches in their processes. These are generally 70 to 80% by weight calcium carbonate in a polyolefin carrier resin. Loadings of up to 35% calcium carbonate in the finished product(s) have a signifi cant effect on .
Aug 19, 1986· The present invention relates broadly to a process for wet grinding of natural and synthetic carbonates, as, for example, calcium carbonate in wet suspension systems. The milling of calcium carbonate in the mineral processing industry is steadily increasing to produce, for instance, fillers suitable for paper filling and coating.
In the production of ultrafine calcium carbonate additives, various aspects must be considered when selecting and deciding among available types of processing systems: Fineness range, annual output (uncoated and coated GCC), dry or wet grinding, specific energy consumption, investment costs, plant engineering, running costs and logistical aspects.

Wet and dry coating structure of calcium carbonate pigments with narrow particle size distribution, TAPPI JOURNAL, February 2000, Vol. 83(2)
Daswell wet grinding mill for calcium carbonate is used to produce fine and high quality ultra fine ground calcium carbonate powder in wet milling way. In other words, the calcium carbonate particles are dispersed in a liquid by impact or by attrition. The fineness of the ground calcium carbonate can reach μm or even superfine.
paper and wetweb. Low wetweb strength leads to frequent sheet breaks and thus poor machine runnability. In this work, we have determined the impact of increasing filler content on the strength and pressability of wet web. The results indicate that addition of precipitated calcium carbonate (PCC) filler into sheets substantially reduced their
