Abstract
The invention relates to a preparation method of phosphorous slag superfine powder and belongs to the field of yellow phosphorous. The preparation method includes the steps of feeding phosphorous slag discharged from a yellow phosphorous furnace into an electric dryer for drying after water quenching, then feeding the slag into a vertical mill device for grinding, and performing even stirring to obtain the finished product. The preparation method has the advantages that the production cost and energy consumption can be effectively reduced and environmental protection is facilitated; and the obtained finished product accords with national relative standards, is superior in quality, and can be widely applied to permanent buildings such as hydropower station dams, highways, ports and bridges.
Description
Technical field
The present invention relates to the phosphorus production field, be specifically related to a kind of phosphorus slag submicron powder preparation method.
Background technology
Phosphorus slag is the slag of discharging in the phosphorus production process.The past phosphorus slag is stacked as waste residue usually, contaminate environment.People have developed the method for comprehensive utilization of some phosphorus slags now, be the Chinese invention patent " a kind of preparation method of phosphorus slag submicron powder " of 200810068787.X such as application number, and exist the shortcoming that power consumption is high, cost is high, treatment process is complicated in this patent of invention, the shortcomings such as it is unstable also to exist the products obtained therefrom quality, and purposes is narrow.
Summary of the invention
Main purpose of the present invention provides a kind of preparation method of phosphorus slag submicron powder, can obviously reduce production costs and energy consumption, and can significantly improve quality product.
The technical solution used in the present invention is a kind of preparation method of phosphorus slag submicron powder, and the method may further comprise the steps: after the phosphorus slag shrend that will discharge from Yellow phosphorus furnace, send into electric drying machine drying, then enter Vertical Mill equipment and carry out grinding, restir is even, gets finished product.
As preferably, the temperature of described oven dry is 300～600 ℃, makes the phosphorus slag water content after the oven dry be lower than 0.6%.
As preferably, the temperature of described oven dry is 350 ℃.
As preferably, the time of described Vertical Mill is 15～30 minutes.
