A calcium carbonate production line can produce finished ground calcium carbonate powder in different particle sizes for different applications. Both dry grinding and wet grinding are available. A grinder or grinding mill is the core equipment for a calcium carbonate grinding plant, which can largely determine the fineness of the end product.
The bulk material of calcium carbonate is crushed by the crusher to the feed fineness (15mm-50mm) that can enter the mill. The crushed calcium carbonate small pieces of material are sent to the silo through the elevator, and then sent to the grinding chamber of the mill by the vibrating feeder for quantitative grinding.
Calcium carbonate is used in paper mill as a filler material in the alkaline papermaking process. Now a days Calcium carbonate dominant over other papermaking filler materials; though at the first stage of papermaking kaolin was 1st choice. The main reason behind the preference of calcium carbonate is the demand for brighter and …
