Tailings dry discharge
Tailings dry drainage is a new tailings disposal technology, refers to the output of the
mineral processing tailings by cyclone multistage concentration, treatment of
efficient dewatering equipment such as dehydration vibrating screen, to form an
low aqueous precipitation curing slag and can use of the site to pile, slag can
be transported to a fixed location for dry piling.
Process features
1. Process
adaptability is strong, the tailings of coarse, fine particles targeted
treatment.
2. Rapid dry row of
coarse grade tailings by cyclone and dewatering screen.
3. Thickener, filter
to achieve fine-grained tailings dry drainage.
4. Due to the
cyclone and the dewatering screen to achieve most of the dry tailings row,
reduces the subsequent concentration and filter equipment load, saves equipment
investment and operation cost.
5. Circulating water
in situ recycling.
Main equipments of tailings dry drainage by sinoninetech
1.High efficiency
concentrated hydrocyclone
The unique design
of the hydrocyclone, under the same operating conditions compared with ordinary
cyclone, the same overflow fineness, classification efficiency of hydrocyclone
at high concentration increased by more than 10%, the highest in the production
practice can be improved by more than 27%, even in the feed concentration of
10%, the underflow concentration can still maintain 65% above, the yield
reached 75%.
2.Tailings
dewatering screen
Dewatering screen
mainly have these characteristics: high frequency vibration, screen angle
design to promote the sieve material continuous emission, processing unit area
is large; high-quality wear-resistant plate, good dehydration effect, long
service life; the objects on the screen with low water content; low noise, low
power consumption and easy maintenance.
3.others filtration
and dewatering equipment
According to the
process requirements, supporting the efficient thickener, vacuum belt
dewatering machine, automatic press filter, the filter press dewatering
equipment, makes the production line a high degree of automation, large
capacity.
sinonine can also provide sand washing plant epc.
