Limestone is quarried for building, roadbeds and landscape construction. Limestone used in manufacturing of cement is especially popular in architecture and many landmarks around the world. Limestone is readily available and relatively easy to cut into blocks or more elaborate carving.
Limestone is one kind of igneous rocks formed by the condensate of magma below the surface. The main component of limestone mine is quartz, feldspar and mica.
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.
