In Philippine, there are abundant of river stone, which is with less mining cost, but with high value. After crushing, screening, the natural river stone is a very good raw materials for many industries, like water conservancy and hydropower, high-grade highways, high speed railway, bridge, airport pavement and runway, municipal engineering, buildings. The sand crushed from river stone are widely used as aggregates of concrete.
One of our customers in Philippine, his river stones are mostly below 6mm, but little parts are about 300mm. He wants to reduce the size into 0-6-19-25-38mm （S1，3/8, 3/4, G1）.
Main Equipment: Jaw Crusher + Cone Crusher
Detail: Vibrating feeder GZG0816 + Vibrating Screen 2YK1548 + Jaw Crusher 400x600 + SC1000M Cone crusher + 4YK1548 + XS2816 Sand Washer.
Raw material: River stone
Final size: 0-6-19-25-38mm 「S1 (40%)，3/8, 3/4, G1」
Application: Concrete, Highway, Construction
In order to reduce the investment cost for him, we didn’t install the big primary jaw crusher, because the big size only engages little part, mostly are about 0-6mm (40%) which can be separated by first screen directly. And 60-100mm (40%), which can be fed into the cone crusher directly. We install a set of a 2-layer vibrating screen 2YK1548 before the crusher, to screen out of the 6-100mm and 100-300mm (20%), we just need to crush 100-300mm by PE400x600 Jaw Crusher, and then put all the +6mm material to Cone Crusher SC1000M. After that, we separate all the crushed material to 0-6-19-25-38mm by one set of 4YK1548 Vibrating Screen. At the same time, we wash all the sand by one set of Sand Washer XS2816.
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.
