What are the defects of phosphorus slag ball mill? In the existing technology, phosphorus slag grinding equipment mainly uses dryers and ball mills. However, due to the large water content of phosphorus slag, the grindability and abrasiveness are also very poor. Using a dryer and ball mill system for drying and grinding, the power consumption of the system is as high as 80KMh/t, and the processing capacity is small, making it difficult to meet the needs of processing a large amount of waste residue for grinding. In view of the technical shortcomings of ball mill grinding phosphorus slag powder, vertical phosphorus slag grinding mill has become a better choice. As a vertical mill manufacturer, today Guilin Hongcheng will introduce to you the advantages of vertical mill blast furnace phosphorus slag powder.

The technology of ball mill grinding phosphorus slag powder is divided into open flow system and circle flow system.
Open-flow system ball mill grinding phosphorus slag powder technology: the materials are metered and fed into the ball mill, and the materials coming out of the ball mill are the finished products. This process is the earliest applied slag powder grinding technology. It has the characteristics of simple process, reliable production, low technical requirements for operators and low investment.
The unit power consumption for grinding 420m2/kg specific surface area slag powder is about 100kWh/t. This process has low grinding efficiency, high energy consumption, high unit product cost, small stand-alone machine capacity, and difficulty in adjusting product fineness. The current high-energy-consuming grinding method is not suitable for the development direction of modern enterprises.
Compared with the open-flow grinding process, the product fineness is convenient to adjust, which can reduce the phenomenon of over-grinding of materials. The grinding efficiency is relatively high, and the single-machine capacity has increased. However, the problem of complex system and small single-machine capacity still exists. Compared with the advanced vertical mill blast furnace phosphorus slag grinding process, the unit power consumption for grinding 420m2/kg specific surface area slag powder is about 75kWh/t. The consumption of grinding body is above 300g/t, and the operating cost is high.
Vertical mills occupy less land area and increase land utilization efficiency. The vertical mill blast furnace phosphorus slag powder grinding system uses the exhaust gas generated by the yellow phosphorus production line as fuel for the hot blast stove to generate hot air. The waste gas generated by the system is used to dry the phosphorus slag in the vertical mill, which not only achieves waste gas reuse, At the same time, the moisture content of the phosphorus slag is reduced, and the grindability and abrasiveness of the phosphorus slag are increased. The power consumption of the entire system can be controlled at 42 degrees/ton, improving production efficiency and output. The vertical mill blast furnace phosphorus slag powder system includes a return transport device, which allows the phosphorus slag entering the system to be completely harmlessly treated to avoid residual phosphorus slag from polluting the environment. Moreover, the particle shape of vertical mill blast furnace phosphorus slag powder is better than that of ball mill ground phosphorus slag powder technology products. Therefore, under the same specific surface area, its product performance is better.
Guilin Hongcheng HLM vertical mill blast furnace phosphorus slag powder production technology is mature, product quality is stable, energy saving and consumption reduction, and it has been maturely applied in the market.
