In the prior art, phosphorus slag grinding mill equipment mainly utilizes dryers and ball mills. Firstly, the phosphorus slag is dried, and then sent to a ball mill for grinding to produce a finished product. However, due to the high water content of phosphorus slag, its grindability and abrasiveness are also poor. Using a dryer and ball mill system for drying and grinding, the system power consumption is up to 80KMh/t, and the treatment is small, which is difficult to meet the needs of large amounts of waste slag grinding. Aiming at the technical defects of ball mill grinding phosphorus slag powder, vertical grinding of blast furnace phosphorus slag powder has become a better choice. As a manufacturer of blast furnace phosphorus slag grinding mill machines, HCMilling(Guilin Hongcheng) will introduce the advantages of vertical mill of blast furnace phosphorus slag powder to you below.

Phosphorus slag is a solid industrial waste produced during the production of yellow phosphorus. Its chemical composition is: Ca0: 47-52%, Si02: 40-43%, P20s: 0.8-2.5%, Al203: 2-5%, Fe203: 0.8-3.0%, F: 2.5-3%. The potential mineral phases are pseudowollastonite, lance spar, and a small amount of apatite. About 90% of its structure is made of glass, and for each ton of yellow phosphorus produced by the electric furnace method, 8-10 tons of phosphorus residue are produced as a by-product. Currently, the utilization rate of waste residue is not high, and a large amount of waste residue is stacked in the sky, which not only occupies a large amount of land, but also P20s and other harmful elements in phosphorus residue can seep into the ground in the rain, causing water pollution and soil pollution. Therefore, the comprehensive utilization of yellow phosphorus waste residue is an urgent issue to be solved at present. An effective treatment method for phosphorus slag is to grind the phosphorus slag fine and then add it to cement for use as a mixture in the concrete industry.

Therefore, what are the advantages of vertical grinding of blast furnace phosphorus slag powder? The vertical mill occupies less land area, increasing land utilization efficiency. The phosphorus slag powder grinding system of the blast furnace vertical mill uses the tail gas generated by the yellow phosphorus production line as the fuel for the hot blast furnace to generate hot air. The waste gas generated by the system is used to dry the phosphorus slag in the vertical mill, not only achieving waste gas reuse, but also reducing the water content of the phosphorus slag, increasing the grindability and abrasiveness of the phosphorus slag. The power consumption of the entire system can be controlled at 42 degrees Celsius per ton, improving production efficiency and output. The blast furnace phosphorus slag grinding mill machine system includes a return transportation device, which allows the phosphorus slag entering the system to be completely harmless treated to prevent residual phosphorus slag from polluting the environment. Moreover, the particle shape of the vertical mill for blast furnace phosphorus slag powder is superior to that of the technical product for ball mill phosphorus slag powder grinding. Therefore, under the same specific surface area, the product performance is better.
