Feasibility Study of Limestone Mining Project
The main component of limestone is calcium carbonate (CaCO3). Lime and limestone are raw materials used in large quantities for building materials and industries. Limestone can be directly processed into stone and fired into quicklime. Quick lime CaO absorbs moisture or adds water to become slaked lime. The main component of slaked lime is Ca(OH)2, which can be called calcium hydroxide. The slaked lime is formulated into lime slurry, lime paste, etc., which are used as coating materials and brick and tile adhesives.

Judging from the current domestic and foreign demand for limestone, the world’s annual demand is about 1.2 billion tons, but 80% is for general use. High-quality lime has a large market gap due to few resources and low output.
The overall investment of the 500tph limestone grinding powder production line is relatively small. Enterprises can reasonably purchase production line equipment according to their needs. K series vertical mill is a new type of equipment, which greatly improves the utilization rate of limestone powder and can reduce investment costs for enterprises.
