[0002] Cement processing, a powdery hydraulic inorganic gelling material, after adding water and stirring into a slurry, can harden in the air or in water, and can firmly glue sand, stone and other materials together. The early mixture of lime and volcanic ash is very similar to the modern lime volcanic ash cement. It is used to glue the concrete made of crushed stone. After hardening, it not only has high strength, but also can resist the erosion of fresh water or salt water. For a long time, it has been used as an important gelling material and is widely used in civil engineering, water conservancy, national defense and other projects. Limestone is one of the raw materials for cement production. Limestone is broken into particles with uniform and moderate particle size before ball milling, which can improve the quality of ball milling.
