Phosphorus slag powder production process for concrete

Release date: 2024-03-11 13:56:39

In recent years, phosphorus slag powder has been widely used in concrete, which has made the phosphorus slag powder production market booming. As a manufacturer of phosphorus slag vertical mills, Guilin Hongcheng's phosphorus slag vertical mills are the main equipment for producing phosphorus slag powder. Today we will introduce to you the production process of phosphorus slag powder for concrete.

Concrete usually refers to cement concrete. Cement concrete admixtures are materials added during the concrete mixing process to improve the properties of concrete. What I want to introduce to you today is the production method of concrete mineral admixture, namely phosphorus slag powder.

The production process of phosphorus slag powder for concrete: first dry the phosphorus slag until the moisture content is less than 1% and then screen it to remove coarse particles with a particle size of more than 5 mm, and use fine particles with a particle size of less than 5 mm as raw materials. The iron-containing impurities are removed through magnetic separation, and then sent to the phosphorus slag vertical mill to grind into fine powder with a particle size of less than 80 μm. Check its activity, and then add active additives according to the predetermined ratio to activate, grind at the same time, and finally make The finished micro-powder product with a particle size of ≤80 μm and a specific surface area of 300 to 600 m2/kg is inspected, weighed, and packaged before leaving the factory. The finished product is a concrete mineral admixture. The concrete mineral admixture phosphorus slag powder is used in concrete, which can significantly improve and enhance the workability, mechanical properties, durability and volume stability of concrete. It is an indispensable admixture for the production of high-strength and high-performance concrete. Coal ash and blast furnace slag powder are both listed as the sixth admixture for concrete. Phosphorus slag powder can not only improve the performance of concrete, but also is low cost. A new way has been found for the utilization of yellow phosphorus waste residue from the electric furnace process, which can turn harm into benefit and help improve the environment.

In these phosphorus slag powder production processes for concrete, phosphorus slag grinding is an important process. The phosphorus slag vertical mill is used for grinding, which has the advantages of energy saving, high efficiency and good drying effect.
