Nov 04, 2019 This is where simulations come in. Simulations are necessary to determine how the primary crusher will perform and how its performance will affect load downstream. There are a number of software programs out there that simulate the aggregation process which can give you a good idea of the crusher’s real-world performance.
Read MorePrimary Crushing. The primary jaw crusher is the first stage of processing in most sand, gravel, and mining operations. Material that has been excavated from the ground (Pit run) or blasted (Shot Rock) is fed to a large crusher, typically a jaw crusher, where it

Sep 02, 2019 HSI crushers can be primary or secondary crushers. In the primary stage, HSIs are better suited for softer rock, such as limestone, and less abrasive stone. In the secondary stage, the HSI can process more abrasive and harder stone. CONE CRUSHER. Cone crushers are similar to gyratory crushers in that they have a mantle that rotates within a ...

Secondary crushers use the same size bottom shells as certain size primary crushers, but different size top shells, mainshaft and spider assemblies. The 30-70 secondary gyratory crusher uses the bottom shell of the 42-65 primary crusher; the 24-60 secondary uses the 30-55 primary bottom shell. PERFORMANCE TABLE. CAPACITIES OF GYRATORY CRUSHERS

Cone crushers are fed with pre-screened material from the primary crusher (usually a jaw crusher or primary gyratory), and the secondary crusher should always, if possible, have a scalped feed. Ideally, the deck on the scalping screen should have a cut point equal to the closed side setting (CSS) of the crusher.

Selecting the right primary crusher is foundational to success at a crushing site. The primary crusher is the engine that drives the rest of the plant; it’s the workhorse that takes blast feed sizes and reduces them to sizes that are manageable for other site components – the belts, the screens, and eventually any secondary crushers – on the road to a finished product.
