River Pebble

Ore properties

River pebble is a kind of pure natural stone. It is taken from the gravel mountain produced by the ancient river bed uplift after crustal movement over tens of millions of years ago. It has been extruded and rubbed during the impact of torrential floods and flowing water. The main chemical composition of river pebble is silicon dioxide, followed by a small amount of iron oxide and trace elements such as manganese, copper, aluminum, and magnesium. They themselves have different pigments, such as red for iron, blue for copper, purple for manganese, yellow translucent for silica colloidal pith, emerald containing green minerals, etc .; because these pigment ions dissolve into the dioxide The types and contents of the hydrothermal fluids are different, so they show a variety of shades, shades, and colors, making the river pebbles black, white, yellow, red, dark green, cyan and other colors. Most of the river pebbles are near the Haihe River. Black sand grains accumulate on the river pebbles. Cobblestone should occupy more than half of the volume. Because it is widely distributed, it is relatively common and has a beautiful appearance. select.

River Pebble Broken Primary

The natural river pebble raw material is fed to the jaw crusher through a vibrating feeder for coarse crushing, or it can be coarsely crushed with a stone crusher.

Broken river pebble

The materials crushed by the jaw crusher can be treated in two ways according to the actual production situation: one is first stored in the transfer pile, and then the material is divided by the transfer pile; the second is directly transferred to the medium and fine crushing equipment ( The better river pebble crusher is a cone crusher). This is also the reason why some production lines have high production and operating costs. First of all, due to the design of the river pebble crusher production line, if the output of the primary crushing is higher than the throughput capacity of the secondary crushing, and there is no intermediate stockpile in the middle, a material blocking phenomenon will occur, which will cause unnecessary downtime maintenance. Secondly, the use of medium and fine crushers is part of the design. In the design of the river pebble crusher, an impact crusher is used, which causes the wear parts to be consumed too quickly and the replacement frequency is high, which directly affects the production cost.

River Pebble Broken River Pebble Shaping

After being crushed by a cone crusher, part of the river pebble can reach the particle size of the finished sand. Most of the grain types and sizes can not meet the needs of high-quality engineering construction. Crushing and shaping, and sand washing the qualified finished sand to reduce the dust content in the product and increase the added value of the product.
