High Purity Natural Limestone Powder

Our High purity natural limestone powder is produced from natural high-grade limestone ore from our own mines, processed only through pure physical processes such as crushing, grinding and classification. No chemical addition or modification is made throughout the process, completely retaining the mineral properties of natural limestone. Our High purity natural limestone powder has high calcium carbonate content, few impurities and stable chemical properties, and is a high-purity natural mineral filler and raw material.

Different from synthetic precipitated calcium carbonate, our High purity natural limestone powder belongs to natural heavy calcium powder, with high density, strong filling performance and excellent temperature resistance. It does not decompose at high temperature and performs stably. We select high-quality ore layers in layers from the mining stage, remove impurity interlayers to ensure high purity and stable composition of each batch. With natural high purity and large-scale cost advantages, our High purity natural limestone powder is widely used in high-end fillers, building materials, environmental protection and other fields.

● High-end plastic filler: Used as natural mineral filler to improve product rigidity and dimensional stability and reduce cost.

● High-grade building materials: Used for artificial stone and decorative mortar, with natural texture, stable and durable performance.

● Environmental desulfurizer: Used as calcium-based desulfurization raw material, natural and environmental friendly, with low operating cost.

● Pharmaceutical and food carrier: Can be used as inert carrier and auxiliary material for medicine and food, natural and safe.

We own our own high-quality limestone mines with sufficient reserves and stable grade, which guarantees the quality and continuous supply capacity of High purity natural limestone powder from the source. The mines implement layered mining, preferring high-calcium low-impurity ore layers and removing weathered layers and impurity interlayers to ensure stable raw ore quality. Supported by multiple automated crushing and grinding production lines, we have sufficient annual production capacity to stably guarantee continuous bulk supply for large and medium-sized customers.

We have established a full-link quality control system from mines to finished products: ore layer sorting is implemented in the mining stage to ensure raw ore grade; particle size distribution and composition fluctuation are monitored online during production; calcium carbonate content, fineness, whiteness and impurity indicators are tested batch by batch before finished products leave the factory. We strictly control composition deviation between batches to ensure stable product performance and avoid affecting downstream production due to raw material fluctuation. Factory inspection reports can be provided with the goods to support customers' incoming re-inspection.
