Stone Crushing without screening is known as open circuit broken. The process is simple but the product size is unstable. O/Solutions/Stone-crushing-and-screening-plant.htmlre 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./Solutions/Stone-crushing-and-screening-plant.html

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 limestone 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 limestone crushing plant to reach production size requirements.
