The first Stage: primary crushing
The limestone passes through the silo and is evenly fed by the vibrating feeder. It is transported to the jaw crusher for primary crushing. After primary crushing, the raw material and the fine material screened by the vibrating feeder are transported from the belt conveyor to the transfer stack.
The second stage: medium fine crushing.
The conveyor belt conveyor evenly conveys the material of the transfer material heap to the cone crusher for fine crushing and screening by circular vibration screen after crushing. Larger particles are sent back to cone and broken again; medium-sized materials are sent to sand machine for fine crushing and shaping; qualified granular materials are cleaned by sand washer as final products.
