river sand mining equipment sale

River sand is a natural stone in the natural state, the water force of long time repeated collision, friction is generated, its composition is complicated, the surface has a certain smoothness, nonmetal ore impurity content much. River sand is smooth particles, relatively clean, wide source; river sand no taste, the sand of the sea salty.

River sand with outstanding contribution to the construction industry. But the sand of the sea on the contrary, the sand of the sea is often mixed with shell and salt, most of the sand containing excessive amounts of chloride ion, corrosion of steel reinforced concrete will, eventually leading to the destruction of building structure, safe use of life to a certain extent, will shorten the building.

However, river sand containing the majority of most of the impurities need processing (such as crushing and screening). However, river sand containing the majority of most of the impurities need processing (such as crushing and screening). The German original rotor centrifugal sand making machine crushing equipment is recommended to use the launch of Shanghai SBM. A double cavity type rotor patent design makes on river sand sand process rotor wear is very small, circular lining structure cavity type is more suitable to be river sand making machine hard stone crushing, and easy replacement of wearing parts.

The river sand is used as the main raw material of external wall thermal insulation mortar for crushing and screening, such as bonding mortar plastering mortar with water river is a river sand as the main raw material. The strength of mortar to approximate with quartz sand do. Play loose granular materials skeleton or filling effect in concrete.
