According to users' requirments for product specifications, quality, and the
different needs, it can produce high-quality artificial aggregates by automatic
control. Adopted PLC intelligent control technology, the crusher efficiency
increased by 20% to 30%.
The advanced technology of green semi-dry sand and
gravel processing system, the high degree of automation, take less area.
Compared with the traditional process, the layout can save 35% to 50% (35% of
the flat type, and slope 50%) of the land resources ; The processing wool which
meet the requirements can be fully utilized, abandoned mud and impurities can be
used to rehabilitate and restore the ecological balance; conventional production
of aggregate for each water recycling 2.5 ~ 4m3 / t, and semi-dry sand a
circulation of water consumption is only 0.8m3 / t, now part of the hydropower
station to reach 0.6m3 / t, are trying to achieve the indicators of 0.3m3 / t to
achieve zero emissions; a substantial increase in the implementation of the
automation and control equipment utilization, the conventional production of
electricity consumption for 9 ~ 12kWh / t, semi-dry sand of 3.5 to 4.5kWh /
t.
The design from the Master Plan layout, monomer shape, layout, water
supply and drainage, semi-dry sand making technology is in accordance with the
principles of "environmental security". Low noise, remove dust, and noise less
than 80dB, and dust content in the air is less than 30mg / m3. The use of
energy-saving and environment-friendly production equipment and production
process development, industrial production, green open space, hardening channel,
aggregate and artificial sand does not require secondary dehydration for
qualified products, sand containing water rate at 3% ~~ 4%, the aggregate
moisture content of less than 1%, no dust, and green manufacturing
process.
Semi-dry technology of artificial sand hydropower station Shatuo
Shatuo Hydropower Station 9 of the Wujiang River main stream in the cascade
development program, a total installed capacity of 1120MW; dam is a roller
compacted concrete gravity dam, a total of 2.708 million Concrete m3, of which
normal concrete 1.1973 million m3, and 1.5107 million m3 of RCC; aggregate
processing system design capacity for the coarse crushing processing capacity of
1500t / h, finished aggregate production capacity of 1150t / h, requiring a
total preparation of sand and gravel aggregate of approximately
595.76 ×
104t, crushed stone (large stone, boulders, stone, stone) 387.24 × 104t, sand
208.52 × 104t, 150 000 m3 of concrete required to meet the peak months of Shatuo
Hydropower Station pouring strength of sand and gravel aggregate.
