limestone stone crushing plant - shanghai zenith company
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.
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.
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.
granite stone crushing plant - shanghai zenith company
Granite is one kind of igneous rocks formed by the condensate of magma below the surface. The main component of granite mine is quartz, feldspar and mica. The crushed granite rocks also can be used in cement or to be filled in Dams. In addition to being used as advanced architectural decoration project and the hall ground, Granite is also the best material for sculptures.
Big granite materials are fed to the jaw crusher evenly and gradually by vibrating feeder through a hopper for primary crushing. After first crushing, the material will be fed into cone crusher by belt conveyor for secondary crushing; then the crushed granite materials will be transported to vibrating screen for separating. After separating, the aggragates that can meet your requirements will be separated out as final products, while the other aggragates will be returned to cone crusher. This whole process can form a closed circuit for aggragates. Size of final products can be combined and graded according to your specific requirement.
