Recent years due to the reduction of natural sand or even disappear,
artificial mechanism sand aggregate into large-scale projects, key projects such
as the Three Gorges Project, the main material required. Vigorously develop
the infrastructure of railways, highways, bridges, and hydroelectric power
plants, the greatest demand is a high quality mechanism sand aggregate.
Mechanism sand aggregates production equipment due to different construction
standards, the requirements of the material and the material fineness is also
different. The existing sand resources are limited, continuous mining, making
the sharp drop in the standard GB sand. With the increasingly high building
standards, the standard aggregate production also will be improved, this
prompted the gravel equipment technology continues to evolve, new
sand equipment came into being.
This was initially dug out by a 90 tonne
Hitachi excavator, which has now been replaced by a 974 Liebherr heavy duty
excavator fitted with a specially made ripper tooth bucket. To date Safedem has
demolished and recycled more than 150,000 m3 (5.3 million ft3) of concrete and
sent substantial tonnages of rebar for reprocessing,
Work is still ongoing on
this massive job, and current Safedem estimates place the completion of
demolition down to the top of the bunker floor level being achieved by late
2014.
Tracked (also called tracked screen mobile crushing machine or crawer type
vibrating screen) is perfect for the quarry and recycle applications where
mobility and production are needed.
A steep angle for the primary screen-box
ensures that the majority of the material is processed in the initial impact
area. The majority of the undersize is removed during initial impact. Only
near-size material passes to the secondary screen-box. This may be set flat
enough to ensure any remaining material is screened efficiently.
Hongxing
Heavy Industry produced by the mechanisms of sand production line equipment
since the successful development of the market by domestic and foreign
investors, especially in open sand plant, do stone quarry aggregate investors a
great deal of profit margins. Carefully designed and manufactured the impact of
sand making machine, is a set of internationally advanced technologies in one
high-efficiency, high reliability and high-quality sand products.
Clean grade
of materials, at very high output, are produced as material is exposed to large
screening area. The tracked vibrating screen offers durability and the high
frequency screen box for unsurpassed screening efficiency.
