Abstract
In this study, the surface coating (modification) of micronized calcite (CaCO3, d50=135 μm) in a stirred media (bead) mill with stearic acid was investigated. As a result of 15 min grinding and 5 min coating experiments, a product with d50=2.15 μm and specific surface area of 3.21 m2/cm3 was obtained. The activation rate of this final product as an indicator of coating rate was 97.7%. According to the optimum coating results, the stearic acid rate was determined as 1%, the modification time was 7.5 min, the ball load was 900 g and the stirring speed was 600 rpm.

Abstract
Bu çalışmada mikronize kalsitin (CaCO3, d50=135 μm) stearik asitli karıştırmalı ortam (bilyalı) değirmende yüzey kaplaması (modifikasyonu) incelenmiştir. Yapılan 15 dak öğütme ve 5 dak kaplama deneyleri sonucunda d50=2,15 μm ve özgül yüzey alanı 3.21 m2/cm3 olan bir ürün elde edilmiştir. Kaplama oranının bir göstergesi olarak nihai ürünün aktive oranı %97.7 elde edilmiştir. Optimum kaplama sonuçlarına göre stearik asit oranı %1, modifikasyon süresi 7.5 dak, bilya yükü 900 gr ve karıştırma hızı 600 rpm olarak belirlenmiştir.
