Limestone is mainly composed of calcium carbonate (CaCO3), MO's Hardness 3 degrees. The limestone particles or powders can be used in building materials, road construction, metallurgy, chemical and other industries after crushing or grinding.
Limestone belongs to medium and low hardness, the configuration of Jaw Crusher and Impact Crusher can complete its gravel production operations. If it needs to produce mechanism sand, a sand maker can be configured after the impact crusher.
Vibrating feeder → jaw crusher → vibrating screen → impact crusher → vibrating screen → sand making machine → vibrating screen → sand washing machine → stock pile of finished materials.
1. The bulk limestone material is fed evenly by the vibrating feeder, and conveyed to the jaw crusher for coarse crushing by belt conveyor. The materials after coarse crushing are screened by a vibrating screen and then transported to the impact crusher.
2. After being crushed by impact crusher, the secondary crushed materials will be screened by circular vibrating screen. Larger materials will return to impact crusher for re-crushing. The crushed materials will send to sand making machine for further processing if finer materials and reshaping are needed.
The standard aggregates for general construction are between 0mm to 31.5mm. The vibrating screen can screen them into different sizes.
