During melting of copper ore concentrates an iron silicate is formed. This is passing a groove and is granulated at a temperature of approximately 1250 °C, using a temperature-controlled pressurized water jet. After cooling down in a tank with fresh water the fine particles are separated from the granulate manufactured in this way. Material produced in accordance with DIN EN ISO 11126-3.
Advantages of Coal Slag for Blast Cleaning
– Vitreous amorphous slag.
– Absorbs no water.
– During the manufacture of the abrasive no crushing or grinding procedures are included. Therefore, the single abrasive particle is not broken up and retains its extreme hardness and tenacity which is the case for all particle sizes.
– Dust reduced.
– All constituents are present in oxidized form, predominantly as bonded silicate..
Used as blast cleaning abrasive for all applications fields in conventional corrosion protection on almost all surfaces. Suitable for SA-3, SA-2½, SA-2 and SA-1.
