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.
