River Stone Crushing Processing

【Introduction】:Pebble is a natural stone from the sand mountains generated by the uplift of the ancient river bed which has experienced the earth movement thousands of years ago. They have gone through the impact of the flash floods and the continuous extrusion, frictio

River stone will be fed into jaw crusher for primary crushing by vibrating feeder. After primary crushing, the material will be transferred to secondary crushing machine like Hard Material crusher for further crushing. Usually, we will equip the river stone crushing & screening plant with multi-deck vibrating screen. The vibrating screen is a key equipment to sieve the crushed stones into different grades. The crushed stone that meet the demands will be transported to the stockpile, the other will be sent to secondary crusher for fineness crushing.

Pebble is hard, but the silicon content is very high. Therefore, the design of crushing process is required to be reasonable. We should consider the production cost as well as the investment cost for the pebble crushing line. The losses of jaw plates, hammer and impact plate are very high in the pebble crushing.

So we mainly choose the crushing plant with laminated principle in the crushing line to reduce the losses of the wear parts. The classic equipment configuration with laminated principle is secondary jaw crusher or jaw crusher plus cone crusher. If the clients have higher request for final products shape, the impact crusher can be used for reshaping. Thus, three stage crushing process configurations are formed. Three stages crushing will inevitably lead to a higher investment cost.

But for the long-term operation stones factory, three stages crushing will be very substantial to the production cost reduction. For the material like pebble, which is hard to crush, the two stages crushing with jaw crusher and impact crusher can also be used. But something should be noticed, the two stages crushing with jaw crusher and impact crusher will inevitably lead to the loss of impact crusher hammer. The life of the hammer will be shorter and the proportion of the material that needs to be re-crushed will be higher.

In the plant, raw river stone will probably be fed into jaw crusher for primary crushing by vibrating feeder. After primary crushing, the material will probably be transferred to secondary crushing equipment like hydraulic cone crusher for further crushing.
