High Purity and High Activity for Fast Reactions
We offer Quick Lime Dust. This product reflects our pursuit of "high purity" and "high activity." We use special high-grade, high-calcium limestone as the raw material. It is processed through high-temperature calcination and fine grinding.
Our factory was established in 2017 and has extensive experience in producing calcium-based products. Our team consists of 30 skilled employees, including more than 12 technical staff. We are not just a supplier-we are a trusted expert in calcium oxide materials. Our Quick Lime Dust is a premium-grade product designed for industrial applications.
Key Specifications and Superior Quality
We maintain strict quality control throughout the entire production process, ensuring stable chemical composition and excellent physical properties.
The table below presents our two high-purity grades. Both have an effective calcium content of ≥90%, which is higher than standard construction-grade lime.
The 200 mesh grade is a general-purpose high-efficiency product suitable for stirred reactor systems.
The 325 mesh grade is an ultra-fine, fast-dissolving type with a surface area approximately 40% larger, designed for rapid reaction applications such as dry desulfurization.
Our Quick Lime Dust is designed for demanding industrial applications.
