River stone

River stone is a kind of pure natural stone. It is taken from the sand and gravel mountain that was produced by the uplift of the ancient riverbed after the crustal movement thousands of years ago. It has experienced the impact of mountain torrents and the continuous squeezing and friction in the process of moving water. In the course of tens of thousands of years of vicissitudes and vicissitudes of life, they have experienced waves and water, lost their irregular edges and corners by the collision and friction of gravels, and were buried deep in the ground together with mud and silent for millions of years. The main chemical composition of river pebble is silicon dioxide, followed by a small amount of iron oxide and trace elements and compounds such as manganese, copper, aluminum, and magnesium. They have different pigments. For example, red is iron, blue is copper, purple is manganese, yellow is translucent silica colloidal chalcedony, emerald color contains green minerals, etc.; because these pigment ions are dissolved in dioxide The type and content of the silicon hydrothermal fluid are different, so it presents a variety of shades and shades, making the river pebbles appear black, white, yellow, red, dark green, blue and gray. There are mostly river pebbles near the Haihe River. There are black sand particles on the river pebbles. The pebbles should account for more than half of the volume. Because of their wide distribution, relatively common and beautiful appearance, they are ideal for courtyards, roads, and construction select. River pebble

Process flow

The biggest feature of river pebble is its high hardness and strong abrasiveness. In actual production, it will cause greater wear on the crusher and sand making machine. Therefore, the river pebble stone production line must pay attention to the rationality of the process configuration, so as to reduce the wear cost.

The current typical configuration method is: using a feeder with a screening function, the first crusher uses a jaw crusher to process large materials in the raw material, and the second crusher uses a fine jaw crusher or a cone crusher to process small and medium materials in the raw material. And the material broken down by the head, the material after the second break can be directly applied to the shaping equipment (counterattack breaking/vertical shaft impact breaking), the shaping material is sent to the screening equipment for separation, and the material returned to the shaping equipment , Thus entering the cycle of production fragmentation.


The natural river egg ore is produced into river egg sand after a series of processing such as crushing, sand making and screening. The river egg sand is an important industrial mineral raw material.

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