Historical origin of river pebbles

River pebbles are a kind of pure natural stone, taken from the sandstone mountain produced by the ancient riverbed uplift after the crustal movement of millions of years ago, experiencing the impact of flash floods, running water handling process of constant extrusion, friction.

Main uses of river pebbles

River pebbles are rich in resources, relatively low collection cost and high application value. It is mainly used for water conservancy and hydropower, high-grade highways, highways, high-speed railways, bridges, airport runways, municipal engineering, high-rise buildings, passenger dedicated line, the production of mechanism sand and stone shaping. River pebbles into sand is also widely used as aggregate for concrete.

River pebbles production process

River pebbles from the jaw crusher for coarse crushing work, produced by the coarse material through the conveyor conveyor to the fine crusher for the second fine crushing work, after the fine crushing of river pebbles into the vibrating screen screen out of two kinds of river pebbles, to meet the feed size of the sand machine river pebbles into the sand machine sand, the other part of the return material into the fine crusher. Part of the pebbles into the sand making machine is made into sand, which is cleaned by sand washing machine and made into finished sand, and the other part is crushed into the sand making machine again.

River pebbles production equipment

Jaw crusher: responsible for the coarse crushing process of river pebbles

Cone crusher: responsible for the medium and fine crushing process

Sand making machine: responsible for pebble sand making and shaping process.
