Guangxi Longhua heavy calcium carbonate (referred to as "heavy calcium") is a widely used inorganic filler in industry. Heavy calcium is almost everywhere in our daily lives. Nowadays, market changes have driven the development of heavy calcium towards ultrafine powder and ultrafine modified powder. Therefore, the current development status of the ultrafine heavy calcium industry has become a focus of our attention. First, let's understand what an ultrafine heavy calcium production line is.

Long Hua, Guangxi Precipitated calcium carbonate (PCC), also known as heavy calcium carbonate, is a widely used inorganic filler in industry. Heavy calcium is found in almost everything we encounter in daily life. Market changes are driving the development of heavy calcium towards ultrafine powder and ultrafine modified powder. Therefore, the current state of the ultrafine heavy calcium industry has become a focus of attention. First, let's understand what an ultrafine heavy calcium production line is.

　　I. Raw Material Mining

　　Generally, calcium carbonate products come from three major minerals: calcite, marble, and limestone; the heavy calcium powder made from different stones also differs.

　　1. Stone Comparison

　　(1) Calcite is widely distributed and is a common type of natural calcium carbonate. The powder is soft, light yellow or slightly red due to different trace elements, with a hardness of 3.

　　(2) Limestone is pure white and has a hardness greater than or equal to 3.

　　(3) Marble powder is bluish-white, with slightly lower whiteness, and a hardness between 3 and 4.

　　(2) Mining

　　(1) Calcite ore is washed and hand-picked; no ore dressing is required.

　　(2) Limestone is washed; no ore dressing or purification is needed.

　　(3) Marble has many varieties and complex ore dressing. Intact marble is cut into pieces on site. Those unsuitable for natural marble slabs become calcium carbonate powder; the mine uses blasting to break the stone into large pieces, which are then crushed into smaller pieces by excavators.
