Limestone is mainly quarried for the construction of buildings, roadbeds and landscape construction. Limestone is widely used in cement production for the construction of architecture and landmarks around the world. It is widely distributed and quite easy to be processed into different sizes for block making as well as carving works.
Limestone Crushing Process:
Passing through a hopper, raw limestone materials are fed by vibrating feeder into the jaw crusher evenly and gradually for primary crushing. After first crushing, the material will be transferred by belt conveyor to impact crusher for secondary crushing. The crushed limestone materials will then be transferred to vibrating screen for separation. After separation, products in required size will be retained as final products, while the rest will be returned to the previous impact crusher for recushing until getting all required sizes. In this way, the whole line completes a closed circuit crushing process. We can separate different sizes according to your requirement.
Grind the limestone to ultrafine mill process:
First, vibrating feeder feeds limestone materials into grinding chamber evenly and gradually. After being grinded, the powder will be blowed to cyclone by blower. Then the material will be transferred to storage room through pipes, and then will be discharged as final products. The whole process works in a negative pressure environment. First, through pipes, the air from the blower enters the cyclone collector above the storage room along with powder, and then returns to the blower through return pipe. In the way, air can be recycled. There is a powder locking equipment under the cyclone, which isolates the outside positive air pressure and the negative air pressure inside cyclone. And this ensures high productivity. In addition, the residual air and dust under the main unit will be transferred to dust catcher equipment through pipes and be cleaned there. The clean air will be discharged so that environment will be protected.
