Primary Crusher an overview ScienceDirect Topics

The broken stone is dumped into a primary crusher where the large rock fragments are broken into smaller sizes. Crushing to the proper size usually occurs in stages because rapid size reduction, accomplished by applying large forces, commonly results in the production of excessive fines (Rollings and Rollings 1996 ).

TECHNICAL NOTE PRIMARY CRUSHER OPTIMAL FEED

The search for a primary crusher optimal operation necessitates the development of a procedure able to relate the fragmentation from blasting with the crusher feed. This is
