Pebble crushing


River pebbles/pebbles are hard solids formed after thousands of years of mountain and water impact and flowing water transportation.
River pebbles are hard in quality and strong in pressure resistance. They are the main material for the production of machine-made sand and gravel, meeting the requirements of artificial sand and gravel in various places.

pebble sand making flow

The river pebble/cobblestone sand making process is divided into three stages: coarse & fine crushing, sand making & screening, and sand washing & recycling.

The first stage: coarse & fine crushing
The materials are uniformly fed by the vibrating feeder through the silo and transported to the jaw crusher for coarse crushing. After the coarse crushed materials are screened by the vibrating screen, they are conveyed by the belt conveyor to the cone crusher for medium and fine crushing.

The second stage: sand making & screening
The crushed materials are transported by the belt conveyor to the sand making machine for fine crushing. The fine crushed materials are then screened for coarse sand, medium sand, fine sand and other specifications through a circular vibrating screen.

The third stage: sand washing & recycling
For those with strict requirements on the powder content of sand, a sand washing machine can be installed behind the fine sand, and the sewage discharged from the sand washing machine can be recycled through the fine sand recovery device. On the one hand, it can reduce environmental pollution and increase the sand production output.
