2020.9.16 Compared with compression crushing, impact crushing will create more fines within the circuit, which will cause greater wear if processing abrasive material. This is why rocks with lower silica content are more suited to reduction by impact crushers. When compared with cone crushers, impact crushers often have a lower capital cost, but can ...

MS is manufactured by grinding/crushing natural stones to (0–4.75-mm nominal size) aggregates. So, this study cal-culated the environmental impacts of manufacturing 1-ton MS from rocks (granite or limestone, etc.) and compared it with 1-ton RCA. Seven mid-point environmental impact (EI) categories, i.e. global warming potential (GWP), human-
