The configuration of 10-20 TPH pebble sand making machine is listed as follow:
This pebble sand making line consists of two stes of PEW250 *1000 European type jaw crusher, one set of VSI9526 high efficiency vertical shaft impact crusher, one 3YZS2160 circular vibrating screen and one set of XSD3016 sand washing machine.
The working process of 10-20 TPH pebble sand making machine is recommended as follow:
The dump truck pours stones less than 210 mm into the silo, and feeds them into two pairs of European type jaw crusher by belt conveyor for the first stage of crushing. After the primary crushing, circular vibration screen will select the stones whose size is greater than 40 mm to sent back to European type jaw crusher for re-crushing. The finished sand less than 4 mm is sent to the sand washing machine. The stones whose size ranges from 4mm to 40 mm will be sent to VSI sand making machine. The crushed stones are screened by circular vibration screen, and the finished sand is washed by sand washing machine. Then they will be sent to the finished area by belt conveyor. The unqualified stones are crushed again by sand making machine, thus forming a closed-circuit circulating crushing system.
