Wet Grinding Calcium Carbonate Tappi Soby. The invention relates to a production method for superfine modified heavy calcium carbonate by wet grinding, which mainly comprises the following steps of 1 adding calcite into a jaw crusher to obtain crushed coarse grains 2 feeding the crushed coarse grains by using a vibrating machine into a flour mill …
calcium hydroxide to form calcium silicate, which makes recycling of lime difficult and reduces the activity of lime when the lime mud is calcined [2]. Currently, no commer-cial process exists to reuse the causticized calcium carbon - ate (CCC) with a moderate amount of silica. Many researchers have studied the problems caused by silicon.
