NARROW PARTICLE SIZE DISTRIBUTION CALCIUM CARBONATE AND METHODS OF MAKING SAME |
| 摘要 |
<p>Calcium carbonate particles having very narrow particle sizes with a controlled D98 and minimal ultrafines (very small particles) are described. The particles are prepared by grinding a feedstock in a centrifugal grinding mill, which utilizes very high centrifugal forces to impact the particles with each other or grinding media.</p> |
