Recommended solution

1. Primary crushing stage

The river stones (pebbles) are evenly fed into the coarse crusher (jaw crusher) by the feeder for preliminary crushing, and the crushed materials are transported to the next stage.

2. Secondary crushing stage

The coarsely crushed river stones are sent to the cone crusher by the conveyor for further crushing. The cone crusher adopts lamination crushing, and the crushed particles are relatively better.

3.Screening stage

The river stones after fine crushing by the cone crusher enter the vibrating screening machine, where they are separated into stones of different specifications, and those that meet the requirements are transported to the finished product pile.

4. Return material crushing stage

The river stones that do not meet the specifications separated by the screening machine must be returned to the cone crusher for further crushing until they meet the requirements of the finished product specifications.
