Fine Ceramics Production Process | Introduction to Fine …
Raw powder and solvating media (such as water) are fed into a mill with ceramic balls. This ball mill is then rotated or shaken to create a uniform mixture (called a slurry), with evenly distributed particles of various sizes. Adjustments are made by adding raw powder and binder dispersants throughout this process.

What Are the Differences between Dry and Wet Type Ball Mill?
The water can wash away the fine particles in time to avoid over-grinding. The wet ball mill has a low noise, and low environmental pollution. The wet ball mill has a simple transportation device with less auxiliary equipment, so the investment is about 5%-10% lower than that of a dry ball mill. The grinding particle size is fine and uniform.

Ball Mills
Ball Mills. In ceramics, ball mills are used to grind down materials into very fine particles. Materials such as clay and glaze components can be broken down in a ball mill by getting placed into rotating or rolling jars with porcelain balls inside them. During milling, the porcelain balls pulverized the materials into an incredibly fine powder.
