Sinonine sand washing plant can be applied to various sand production fields to clean, remove impurities, screen, grade, dewater. Sand products used in the different areas can be produced by different sand washing plants. Sinonine has developed a series of sand washing plants for construction, foundry, glass making, and oil fracturing, etc for processing different kind of sand, such as quartz sand, artificial sand, dune sand, river sand and other raw sand.
Construction sand washing plant
The crushed sand or river sand for construction has a particle size of about 0-4.75mm. It is necessary to clean the soil and recycle fine grained sand to finally get the finished construction sand
that meets the needs of the construction industry. Construction sand washing plant mainly includes sand washing, fine sand recovery, dewatering, water treatment and other functional modules. Crushed sand or clay-bearing shall be washed by raw the sand washing machine
for one or two stages, after washing the sand slurry is sent to the dewatering screen
, sand slurry containing a certain amount of water then enters into the hydrocyclone for fine sand recovery, and the recovered fine sand is returned to the dewatering screen for dewater, the tailings is the final impurity containing soil and it is discharged into the thickner for water treatment.
Oil fracturing sand washing plant
Particl size specifications of conventional frac sand
are divided into 20-40 mesh, 40-70 mesh, 70-120 mesh to meet the needs of different stages.The original sand by powerful attrition scrubber
to remove impurities wrapped on the surface of sand , and then washed by the sand washer
water to remove clay and other impurities, the cleaned sand is classified through hydraulic classifier
to obtain sand products suitable for requirements of different particle size range, qualified sand products through the dewatering process to get dry finished frac sand products.
Glass sand washing plant
Ordinary glass sand
requires Fe2O3 content less than 0.03% and its particle size is generally controlled between 100-600 microns. Raw sand is pre-cleaned and screened to remove part of impurities, and then enters the powerful attrition cells to scrub off the impurities wrapped in the surface, and then enters the hydraulic classifier
for particle size classification, and sand slurry then enters the magnetic separators
for iron removal, finally through dewatering and drying the glass sand
products are obtained.
Foundry sand washing plant
Silica sand for foundry requires silica sand
to be pure and without impurities, with a round grain shape, a content of SiO2 of around 94-98%, and a size of 50-150mesh. The raw sand suitable for making foundry sand is first screened to remove impurities, and then scrubbed and washed by a powerful scrubbing machine
, and then washed by a sand washing machine
. After washing, the sand slurry is classified by a hydraulic classifier
, and then dewatered and dried to obtain foundry sand
can provide a complete set of sand washing and purification solution and equipmets. In addition to the conventional treatment process mentioned above, It can also use particle size classification, strong magnetic separation, acid pickling and other technological processes according to the property of quartz sand to produce high-purity quartz sand products with different requirements.
