The reserves of Pebbles are very rich. Pebble is the best production of materials used in construction sand and artificial sand, broken pebble prices relatively low.
Pebble main chemical composition is silica, followed by a small amount of iron oxide and trace amounts of manganese, copper, aluminum, magnesium, and other elements and compounds, the quality is hard, having a compressive strength, wear and corrosion-resistant natural stone properties, is a desirable the materials used in construction, civil construction and concrete aggregate the level stable layer materials in road construction. , Along with investment in infrastructure projects, building concrete aggregate demand increasing, pebble mining lower cost than blasting gravel and less impact on the ecological environment, and strong government support.
Pebble production process:
With the investment in infrastructure projects, building concrete aggregate demand is increasing, behind its huge potential for economic development, revealing a huge demand for sand and gravel, investment pebbles made ??of sand will slowly form a new investment hotspot. Pebbles sand making, requires a series of sand making equipment, the main equipment jaw crusher, vibrating screen, sand making machine, sand washing machine.
