Stone Crusher Plant Price List
In stone crushing production line, the feeder or screens separate large blocks from finer rocks that do not require primary crushing, thus reducing the load to the primary crusher. Jaw, impactor, or gyratory crushers are usually used for initial size reduction.
The stone that is too large to pass through the top deck of the scalping screen is processed in the secondary crushing plant. Cone crushers are commonly used for secondary crushing.
The output from the secondary crusher and the throughs from the secondary screen are transported by conveyor to the tertiary circuit, which includes a sizing screen and a tertiary crusher.
Stone Crushing Machine Selection
The choice of stone crushing machine depends on the properties and amount of material to be crushed. Gyratory and jaw crushers are the bulk of primary crushers applied in mining operations modern time. Roller impact crushers, VSI crusher are often used in secondary crushing operations. Cone crushers remain the most popular for fine crushing applications, although some mines use vertical impact crushers for tertiary and quaternary crushing.
The major equipment in a primary crushing circuit usually includes only a crusher, vibrating feeder and belt conveyor. Secondary and tertiary crushing circuits have the same basic equipment items, along with screens and surge storage bins. There are also mobile crushing plant which could be easily move on the working site.
