For fine powder production, ore jaw crusher, impact crusher and cone crusher crushing directly after the Raymond mill type, product fineness 100-325 mesh, the specific process is as follows:
The first stage: rough broken
Limestone bulk materials by silo by vibrating feeder uniform feeding, conveying to the jaw crusher for crushing, crushing materials after sieving shaker, transported by belt conveyor to a crusher.
The second stage: crushing
Delivery to the back breaking the material after crushing counterattack broken broken, the circular vibrating screen screening after counterattack broken broken material, larger particles back to counterattack broken broken again; for more fine products or plastic, the crushed material into the sand making machine for further broken plastic.
The third stage: Milling
The crushed limestone pieces of material by hoist sent to the bunker, and then by the uniform quantitative vibration feeder into the grinding chamber for grinding.
