Description

Technical Field

[0001] The invention relates to the technical field of phosphorus slag powder production, in particular to a phosphorus slag powder grinding device. Background Art

[0002] Phosphorus slag powder is an important concrete admixture. Adding an appropriate amount of phosphorus slag powder to concrete can not only save cement, improve concrete performance, but also protect the environment. Studies have found that since phosphorus slag powder has hydraulic activity, after being added to concrete, it is again stimulated by the alkalinity of calcium hydroxide, the hydration product of cement clinker, to increase the strength of concrete and generate gelling hydration products. Therefore, the hydration of phosphorus slag powder is slower than that of cement clinker, and it has a retarding effect on cement concrete, resulting in a decrease in the early strength of concrete. Our company has conducted multiple project studies on phosphorus slag powder products in the early stage, and improved the relevant characteristics of phosphorus slag powder through technical means, obtained a number of research results, and achieved good economic benefits after being put on the market.

[0003] After searching, the application with patent application number 201620422544.1 discloses a phosphorus slag grinding system, which includes a phosphorus slag feeding device, a phosphorus slag grinding device and a discharging device, wherein the phosphorus slag feeding device is connected to the phosphorus slag grinding device, and the discharging device is connected to the phosphorus slag grinding device; wherein the phosphorus slag grinding device includes a vertical mill and a hot blast furnace, wherein the vertical mill is connected to the phosphorus slag feeding device, and the hot blast furnace is connected to the air inlet of the vertical mill, and the fuel of the hot blast furnace is the tail gas of the yellow phosphorus production line. The phosphorus slag grinding system of the present application grinds the phosphorus slag through the vertical mill, and the vertical mill occupies less land area, thereby increasing the land utilization efficiency. In addition, the tail gas generated by the yellow phosphorus production line is used as the fuel of the hot blast furnace to generate hot air for the hot blast furnace, or the waste gas generated by the system is used to dry the phosphorus slag in the vertical mill, which not only achieves the waste gas recycling, but also reduces the water content of the phosphorus slag, increases the grindability and abrasiveness of the phosphorus slag, and the power consumption of the entire system can be controlled at 42 degrees / ton, thereby improving the production efficiency and output.
