FactSheet

Using crushing machines at construction sites to reduce the size of large rocks, concrete, or construction rubble can generate respirable crystalline silica dust. When inhaled, the small particles of silica can irreversibly damage the lungs.

Introduction to Crushing

silica. The total silica content of a rock issilica. The total silica content of a rock is decisive for its abrasive properties: The higher the silica content, the higher the wear on the crusher liners. From experience we know that there is a approximate relationship between the Abrasion Index AI and the silica content of the materialthe material.
