CaCO3 Powder

High quality stone are manually selected at the mines and tested for purity, are sent to works for further processing. Larges lumps are crushed to smaller size and washed to remove any impurities. These chips are ground and micronised as per customer requirements.

There are various kinds of Calcium carbonate powder with mean size from 5µm - 300µm (50-2500mesh). Our products applications for many industries: Plastics, Paint, Paper, Rubber, Masterbatches, Art marble…
