River Sand is a kind of small particle produced by repeated impact, collision or friction of stone by river in a long period of natural state. Sea Sand refers to the sand eroded by sea water without desalination, mostly from the junction of sea water and rivers, containing corrosive salts. River sand and sea sand are different, how to distinguish them? And what is different between sea sand washing plant and river sand washing plant?
1.Different Appearance between river
sand and sea sand
In terms of appearance color, the sea sand
is darker, dark brown and lighter. The color of river sand is relatively
brightly yellow.
From the aspect of particle size, the grain
size of river sand is coarser, with moderate surface roughness and less
impurities. Sea sand is very fine, even some like powder, this is absolutely
not used.
In terms of particle fragments, sea sand
generally has fragments such as shells, while river sand has pebbles of
different sizes.
2.Different Specifications between river
sand and sea sand
The river sand used in the construction has
certain specifications. In the process of river sand screening, river sand is
generally divided into 4-8 mesh, 8-16 mesh, 10-20 mesh, 20-40 mesh, 40-70 mesh
and 50-100 mesh, which refers to the number of sand particles within one inch
circle. There is no such fine and clear rule classification for sea sand.
3.Different Handle between river sand
and sea sand
Grab a handful of sand and then beat it
off. It’s sea sand that feels sticky and doesn’t clean. If it’s not sticky,
it’s river sand.
4.Different Taste between river sand and
sea sand
Taste the taste, found that salty is sea
sand, not salty is river sand. At present, there are also many Sea Sands that
have been desalted. We can soak the sands in the water for a period of time and
taste the taste of the water. The salty and astringent one is Sea Sands.
5.Different Ingredients between river
sand and sea sand
The main composition of sea sand is silica,
the crystal phase is mainly quartz, feldspar and debris particles are less,
mica content is less, and the roundness is also good.
The silicon content of river sand is lower,
the metal ions such as calcium and aluminum are more, and the mica sheet content
is also more. But this is only an average situation in general, sometimes there
are special cases, and it is difficult to have specific quantitative
indicators.
Advantages of River Sand
Sand particles are smooth and clean;
It has a wide range of sources, convenient
materials and low cost;
River sand has no taste, while sea sand has
salt taste;
Good water permeability and air
permeability.
