What is PS Ball

PS Ball is an abbreviation of Precious Slag Ball, an innovative material that can be produced by rapid cooling of slag which generated from steel making process by means of our own Slag Atomizing Technology (SAT). PS Ball is an environment-friendly material proved by Ministry of Environment. It has superior characteristics compared to sand or copper slag in its compressive strength, hardness and antiweathering.  

Application of PS Ball as Abrasive Blasting Material

It is being widely used in the field of ship repair industries and oil refinery plant maintenance for shot blasting purpose, PS Ball itself has shaped in a stable and safe form, not pollutant and harder that Copper Slag or Sand. 

     

Less risky to the operators and neighbors, low levels of dangerous contaminants, such as asbestos (in olivine) and arsenic (in copper slag) Exhaust fewer dust under normal usage conditions than Copper Slag and Garnet Easy use with high productivity without replacing blasting equipments Durability to allow collection, reclamation and reuse Appropriate grain shape and size for the intended application Low environmental impact during storage, use and disposal Easy to supply than Copper Slag and Garnet
