chemical composition Of crushed quartz. the exact composition of slag varies over a range.in general, factors that determine the suitability of slag for usage in composite cement mainly include the fineness of grinding, glass content and the chemical composition.fineness like most of other cement materials, the reactivity of slag is influenced by its surface area.the ball is applied to produce different types of ceramic, glass, and chemical raw materials. the grinding efficiency and wear resistance ability of the ball is far better than ordinary stone ball and cobblestones. So alumina ceramic ball are excellent grinding medium for grinding equipment, such as ball mill, tank mill and vibrating mill.
