Introduction

Limestone in the forms of calcium or slacked lime, mainly includes CaCO3 that can directly be processed into stone material or burned into calcium lime. With CaO as the main ingredient and lump as the common shape, the pure calcium lime is black while the impure is light gray or pale yellow. After absorbing moisture or water, the calcium lime will change into slacked lime with Ca(OH)2 as the main component. The slacked lime can be formulated into lime slurry, paste, motor and so on for being used as coating materials and tile adhesive.The limestone is also the important raw material for numerous industries including construction.

Process

After being blast from the mountain, the limestone less than 1200mm is sent into the vibrating feeder by dumper and then evenly fed into heavy hammer crusher for primary crushing. The large blocks coming out of the primary crusher will be transported to the next crusher for secondary crushing and shaping. After being screened by the circular vibrating screen, the block materials with unqualified size will be returned to the secondary crusher for re-crushing while the finished materials are conveyed to the Finished Product Area.
With the compressive strength of about 150Mpa, the limestone is a kind of soft rock; therefore, it is an economical and reasonable technique to adopt the two heavy hammer crushers to form a closed circuit for crushing twice in the limestone production line.
