Dolomite Calcium Powder

You need a reliable source of industrial minerals. We produce dolomite calcium powder from our own mines in Chaohu, China. Our factory covers over 20 acres and operates 6 automated production lines. A team of 30 skilled workers, including 12 technicians, manages the entire process.

We do not just produce stone powder; we create a stable industrial raw material you can depend on. Our dolomite calcium powder is the result of strict quality control from start to finish.

We control quality at every stage. Our inspectors monitor materials from the warehouse to the final product. The table below outlines our guarantees.

 

We maintain a stable chemical composition, with CaO at 30–32% and MgO at 20–22%. We also offer a low-iron grade (≤0.1%), which is preferred by photovoltaic glass manufacturers. Our focus on purity ensures that the acid insoluble content remains very low, resulting in a cleaner product for your process.

 

You can rely on the consistency of our dolomite calcium powder.

We offer multiple grades to meet the needs of different industries. Our 16–30 mesh size is our best-selling grade and is widely used in glass batch materials due to its stable composition.

We make the cooperation process simple. You provide your requirements for particle size, iron content, and application. We then offer a free sample (up to 5 kg) for testing. After sample approval, a 30% deposit is required to begin production. We provide photo and video updates every 7 days. Shipment is arranged after the remaining 70% balance is paid.

Our dolomite calcium powder is certified under ISO 9001, ISO 14001, and ISO 45001 standards.
