Limestone Production Line

The limestone processing machinery is widely applied in construction applications. Limestone processing operations may include conveying, crushing, screening, size classification, material handling and storage operation. Crushing can be processed in three steps according to final products applications: primary crushing, secondary crushing and tertiary crushing.

Screening is the single most important part of the processing cycle of crushed stone particles. A wide variety of screen types exist, and their selection is a function of the material processed and the final product required. Inclined vibratory screens are most commonly used in stationary installations, while horizontal screens are used extensively in portable plants.

The feeder or screens separate large boulders from finer rocks that do not require primary crushing, thus reducing the load to the primary crusher. Jaw crusher, impact crusher, or gyratory crushers are usually used for initial reduction.

Vibrating screen separates the primary crushed oversized rock from the smaller stone. The stone that is too large to pass through the top deck of the scalping screen is processed in the secondary crusher. Cone crushers or impact crusher are commonly used for secondary crushing, which typically reduces material to about 1 to 4 inches.

Some operation requires tertiary crushing for producing finer particle size for specific application. Cone crusher is often used as fine crushing equipment.
