Ball clay undergoes limited processing. Most is size reduced and some 70% is sold in this form. This allows the clays to be more easily handled and blended. The blending being essential to optimise clay use and to consistently meet customer specifiions. Some are also dried and milled and are dispatched in bulk or bags. For the sanitaryware market some products are .

Ceramic powder processing consists of powder production by milling/grinding, followed by fabriion of green product, which is then consolidated to obtain the final product. A powder is a collection of fine particles. Synthesis of powder involves getting it ready for shaping by crushing, grinding, separating impurities, blending different powders, drying to form soft agglomerates.

· My main desire for using the ball mill on clay is for slip making. I would hope that being able to measure the dry clay accurately will help me make consistently good slip. Also, I am guessing that starting with powdered clay will reduce the number of chunks in my clay needing to be sieved out. Pres Surely I don't need a ball mill, or any other fancy tool. But I am an .

The local clay was ground at varying times from 5 to 20 h with a 10:1 or 20:1 weight ratio of the balls to powder, which produced six different ball milled clays (BMClay1 to BMClay6). Ground clays were then characterized by particle size measurement, Xray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy analysis, and adsorption experiments. .

The ball to powder ratio (BPR) is a processing parameter that is frequently used in both mechanical (ball) milling and mechanical alloying. A number of recent studies provided the BPR as a principal milling parameter while neglecting other parameters, such the vial volume, the diameter and quantity of milling balls and the powder mass. In this experiment, different .
