Ebonygrit is produced from metallurgical slags and provides fast blast-cleaning rates. Three grades are available to suit most common blasting operations. The hardness and high density of Ebonygrit give it a high resistance to fracture with very low dust formation during blasting, as well as faster blast-cleaning speed when compared to local slag abrasives. This abrasive is commonly used for restoration of heavily painted steel bridges, ships and water towers.
Ebonygrit is a disposable high-density blasting slag made from a by-product of copper production. Ebonygrit distinguishes from light-weight blasting slag, due to its high density property.
Typically, the majority of its composition is iron oxide and silicon dioxide, formed when molten slag is quenched in cold water. This cooling process fractures the slag into coarse and angular particles, making it an ideal blasting slag with optimal blasting properties.
Advantages Of Ebonygrit – Copper Slag
- Very high cleaning speed
- Very low dust level
- Lower abrasive consumption
- Crystalline silica levels are less than 1%
“In some cases, the reduction in dust has been at least 70%… The productivity increase has been in the area of 60% faster…” – Decker Inc./Echo Bridge Inc.
Benefits Of Using Ebonygrit
- Reduces slag consumption rate
- Increases blasting productivity rate
