Phosphogypsum itself is a solid waste produced in the process of wet phosphoric acid production, if the phosphogypsum can be reasonably used, it can reduce the benefit of resources and achieve the sustainable development of resources. The main components of apatite are calcium sulfate dihydrate, phosphate ore, residual phosphoric acid, fluoride, acid insoluble matter, organic matter and so on. I take you to understand the apatite grinding equipment and the scope of application.
Want to process phosphatic limestone into powder need to choose a suitable powder making equipment, in the domestic phosphogypsum powder mostly using LM vertical mill, LM vertical grinding is a set of crushing, drying, grinding, grading, conveying in one of the advanced equipment, its process is simple, compact structure, small footprint, high degree of automation, fully closed system, full negative pressure operation, no dust overflow, energy saving and environmental protection advantages. The finished product has many advantages such as uniform particle size, good fluidity, and strong adaptability to the market. It can improve the production efficiency and product quality.
LM Vertical Grinding Mill
Phosphatic limestone powder can be used as raw materials for sulfuric acid and cement; or formulated with gypsum dihydrate as cement retarder, whose performance is basically the same as natural gypsum, and can be used as cement retarder; in addition, as phosphogypsum is rich in calcium and sulfide, it can be used as chemical raw materials after proper processing.
