The sand screening machine is important and the right and suitable sieving machines can
greatly increase the sieving efficiency and commercial benefits. Firstly, we need to know
some basic knowledge about the sand powder.
The sand refers to the particle size of 0.074 ~ 2mm that is washed by rain or rolled by rock after weathering.There are many kinds of sand e.g river sand, sea sand, metal sand, natural sand silted sand. Ordinary river sand is mainly composed of silica (SiO₂).The density of silica is 2.65g/cm3.The thickness of sand refers to the average thickness of sand particles of different sizes mixed together. There are usually coarse sand, medium sand and fine sand. They are existed different area, so sand size and screening demand are different.
For coarse screening and primary screening for the sand powder, and not much sizes of the
powder, we recommend the linear vibrating screen machine, trommel screen and gyratory
sifter machine can apply. For fine sand powder screening, we often recommend tumbler
screening machine and gyratory sifter machine. Especially for tons of large sieving capacity and more than 5 sizes of the sand powder.
If you are in sand industry and would like to know more sieving and conveying solution,
welcome to consult. And we will send you more info about our successful sand sieving cases
and our engineer can freely design the CAD drawings for your application site.
