Process Flow of Limestone Crushing and Processing

Sep 10 2015

Limestone is a sedimentary rocks of crystalline and layered structure. It often used in kinds of construction, chemical, electronics and other industries after processing, and different process has different application. Let's look at the limestone crushing production process.

The first stage: primary crushing

The chunks of limestone is transported to the crushing plant through uniform feeding by feeding equipment (such as feeder). Generally jaw crusher is the primary crushing equipment, crushed limestone is send to next process or stored in the side./

The second stage: medium fine crushing

The crushed limestone uniformly delivered to cone crusher or impact crusher machine for fine crushing by the conveyor belt, then sieved by circular vibrating screen. Larger pellet are returned to the limestone cone crusher for second crushing; medium-grained limestone are send into next process.

The third stage: fine crushing and shaping

Fine crushing and shaping are mainly conducted by sand making equipment(sand or limestone making machine). First, medium-grained limestone or limestone sand carried into the crusher crushing process, limestone treated by the screening equipment (circular vibration sieve) were sieved, and larger grain size limestone sand making equipment returned to the process again, compliance or to meet user demands products are send into the stockpile storage by belt, or directly into the next process for cleaning.

Fourth stage: sand washing Finished

The processed limestone was send into the sand washing machine in the washing machine to filter out the dirt, and products were used in major construction, chemical, road filled and other industries after cleaning.
