River stone crushing line in Ecuador

Process Description

One of our customers in Ecuador, his river stone is most below 120mm, but little parts are about 300mm.

For reducing the invest cost for him, we didn’t install the big primary jaw crusher, because the big size only engages little part, mostly is about 50-120mm, which can be fed into the cone crusher directly. We install a set of two layer vibrating screen 2YZS1237 before the cone crusher, to screen out the little part of big river stone, and then the ones below 120mm are screened out and transported to the hopper, and under the hopper, a small vibrating feeder GZG100-4 is needed for feeding stones into the cone crusher CSB75 continuously. Then crushed by the cone crusher.

If you need to make the sands, a set of VSI crusher will be needed after the cone crusher, for making sand and shaping the outputs into cubic shape. Then the outputs are transported to the vibrating screen for screening out the qualified outputs, the bigger ones will be transported back to the cone crusher or VSI crusher for re-crushing.
