At Cemix, we use only our own exclusive, high purity, carefully selected marble to ensure a homogeneous raw material with a consistent mineral composition.

In a two-stage process with an optical separator and pre-crushing, only very white raw materials are pre-selected and then crushed to a precise particle size range of 0.1 - 4 mm. Only then does the actual grinding process take place. This harmonisation allows us to guarantee a uniform and excellent colour of the final material.

Super white on request: On request, we can pre-select the very whitest material for crushing and grinding, allowing you to order the highest white qualities.

Cost-effective alternative to TiO₂: Cemix Prowhite offers a high-brightness, non-toxic, and natural replacement for Titanium Dioxide (TiO₂), providing significant cost savings without compromising performance.

Stable and narrow PSD range: Our 6 Ring Roller Mills, equipped with an integrated air classifier and triple-stage filtration, deliver exceptionally tight particle size distribution, ensuring every batch meets exact specifications.

Uniform micronization with minimal oversize particles: We use multi-ring grinding that applies uniform pressure across all layers, resulting in uniform milling result.

Reliable D50 and controlled D98: The built-in air classifier actively separates fine particles based on precise airflow and centrifugal forces, continuously adjusting cut size to achieve a reliable D50 and controlled D98 (e.g., D98 < 4 μm, D50 = 0.9 μm).

Clean, dust-free output: The three-stage filtration system captures and recycles airborne fines, maintaining a clean processing environment and preventing cross-contamination, which is critical for high-purity applications.

This advanced setup allows Cemix to deliver precision-engineered GCC with consistent quality, ideal for high-performance applications in plastics, coatings, adhesives, and beyond.
