[vc_row][vc_column][vc_column_text css_animation=”fadeIn”]Grinding<\/strong> constitutes the second stage of fragmentation. It handles already reduced\u00a0 materials (< 10 mm) and brings the particle sizes to micrometric dimensions. It operates through dry or wet (pulp) sorting.<\/p>\n

Different techniques to various degrees implement principles such as crushing, impact, attrition and abrasion. This operation, taken as far as the levels of micronisation, can at the extreme lead to the amorphisation of crystalline structures made use of in mechano-chemistry to functionalise the materials (manufacturing of new binders, activation, etc.).[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column]\n
