PS Ball stands for Precious Slag Ball, which is an innovative material that can be produced by the rapid cooling of slag generated from steel making process by means of our own Slag Atomizing Technology (SAT). It has superior characteristics compared to Garnet sand or copper slag in its compressive strength, hardness, and anti weathering. The liquid steel slag stream is transformed into spherical slag balls of various sizes by the supercooling method of molten slag, using fast heat exchange of the falling liquid steel slag in high-speed airflow. During this process (Sand Blasting Machine & Shot Blasting Machine), free CaO and Fe2O3 are scattered to form a solid PS ball manufacturer or Precious Slag Ball manufacturer and thus produced is in a stable Spinel Structure.
