Özet:

 In this study, the surface coating modification of micronized calcite CaCO3, d50135 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 d502.15 μm and specific surface area of 3.21 m2cm3 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.

 Bu çalışmada mikronize kalsitin CaCO3, d50135 μm stearik asitli karıştırmalı ortam bilyalı değirmende yüzey kaplaması modifikasyonu incelenmiştir. Yapılan 15 dak öğütme ve 5 dak kaplama deneyleri sonucunda d502,15 μm ve özgül yüzey alanı 3.21 m2cm3 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.
