Calcined Dolomite Powder

You need a partner you can trust. We provide a stable supply of high-quality calcined dolomite powder. Our factory covers over 20 acres and is supported by a professional R&D team of 9 experts. We use natural dolomite sourced from our own stable supply chain in Chaohu, China, ensuring consistent material quality.

Our goal is to provide you with a reliable calcium and magnesium solution. We do not just sell minerals; we build dependable partnerships. When you choose our calcined dolomite powder, you choose a worry-free supply.

We use a fully enclosed production line to guarantee quality. The specifications below form the foundation of our promise to you. We focus on purity and stability.

 

For example, our calcium oxide (CaO) content is maintained at 30–32%, and magnesium oxide (MgO) at 20–22%, resulting in a stable ratio of approximately 1.39. This consistency reduces the need for frequent formula adjustments.

 

We also offer a low-iron grade (≤0.1%) for high-end applications such as photovoltaic glass. Advanced equipment, including vertical mills and Raymond mills, ensures precise control of the final product. Every batch is tested to meet your requirements.

Our calcined dolomite powder is available in multiple particle sizes, ranging from 8 to 120 mesh. For example, the 30–50 mesh grade is ideal for flue gas desulfurization. In one case, we helped a power plant achieve over 90% efficiency using this grade.

We support OEM and ODM orders and can customize products to your specific needs. Our quality is backed by ISO 9001 certification. We also provide free samples (up to 5 kg) for testing.

With a monthly production capacity of 300,000 tons, we can deliver standard orders within 3–5 working days after receiving the deposit. We are committed to making your sourcing experience simple and successful.
