Ultrafine grinding of silica can be accomplished in a range of means, including dry ball milling using a global round mill or wet vertical milling. Global sphere mills can be equipped with agate round mills and grinding balls. The dry sphere mill can grind the average fragment dimension D50 of silica product to 3.786 um. In addition, damp vertical grinding is among one of the most efficient grinding methods. Considering that silica does not respond with water, wet grinding can be done by adding ultrapure water. The damp upright mill devices “Cell Mill” is a new sort of grinder that integrates gravity and fluidization technology. The ultra-fine grinding innovation composed of gravity and fluidization fully stirs the products with the turning of the stirring shaft. It clashes and contacts with the tool, resulting in shearing and extrusion so that the material can be effectively ground. The typical fragment size D50 of the ground silica product can reach 1.422 um, and some particles can reach the micro-nano level.
