screening and crushing stone indonesia

Stone crushing and screening plant is formed by crusher and screen machinery connected by belt conveyor. There are many different types of crushing and screening process.They can be categorized into the following elements: the number of broken segments, mechanical configuration of the relationship between crushing and screening machinery, whether materials on the screen is returned.

Stone Crushing without screening is known as open circuit broken. The process is simple but the product size is unstable. Ore broken needs screening, is called closed-circuit crushing. Screening before or after the crushing during the closed-circuit crushing process is divided into inspection and pre-screening.

Pre-screening is screening before the material broken. Fine screening can prevent excessive fragmentation and increase the production capacity of crusher to reduce energy consumption. When the ore contains a large water and mud, pre-screening can prevent and reduce the degree of crushing machine being blocked.

For the flux of the crushing and screening, due to sintering of the stone used in the general requirements of 3-0mm of the content should be greater than 90% (pellets require more detailed), infiltration plant limestone particle size limit of 40mm, and some even up to 80mm on top, it must be carried out into the stone crushing plant to reach production size requirements.

Required equipments in stone crushing and screening plantjaw crusher, impact crusher, cone crusher, vibrating screen, etc. Jaw crusher is used in primary crushing, while the impact crusher or cone crusher will be used in secondary crushing.
