Best Practices for Dust Control in Metal/Nonmetal Mining – Crushing Facilities
Silica, or silicon dioxide (SiO2), is a critical material in many applications, from glass and ceramics to cement and abrasives. But the very characteristics that make silica such an industrial success story also make it challenging to process if quality equipment is not selected. The hard, abrasive nature of silica demands heavy-duty equipment designed …
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 ...
