Boiler slag can be converted into blasting abrasives that are non-hazardous with respect to silicosis. For this purpose, the material is dried, impact-crushed and sieved to achieve the desired grain size, depending on the requirements.
The demand for this material is very high, because its sharp edges make it highly abrasive. Depending on the blasting method and the grain size, it can be used for blasting building materials such as metal or concrete, but also wood.
