5 cold feeders 180tph belt feeding capacity asphalt drum mix plant
with imported motor recuder
1, The optimal design of lifting blades makes high effiency of raw
aggregate drying , and stainless steel coated insulating layer
effectively reduces the heat losses in drying drum, save fuel consumption, improve the thermal efficiency. Drying cylinder combustion zone
adopts wear-resisting, heat-resisting material, which prolongs service life.
2, Chain bucket type hot aggregate elevator with spring tensioner
is driven by shaft-mounted gear reducer, which runs smoothly with
brake motor agianst reverse rotation.
High strength and durable screen mesh with reasonable layout makes
better vibration isolation effort during vibration screen running,
big and wide screen opening makes it convenient to replace new
mesh.Complete seal of whole body, with negative pressure design
inside to avoid dust emission.
3. hot aggregate use rough and accurate weighing(two step weihging
method), combined with automatic impulse compensation program,
which will guarantee high weighing accuracy. Advanced computer automatic compensation function, which will
ensure much more accurate weighing control system.
4, modular and integrated design make plant transportation and
installation convenient, professtional design ensure that there is
enough space for maintenance and safety device, running under the
micro negative pressure circumstance will prevent filler floating.The double vortex mixing tank will reach to a optimum mixing
effect, mixing arm, mixing paddle and liner board are made of
special anti-frication cast steel, all linings are bolted outside
of the tank, easy for maintenance and change. Mixing tank is driven
by double-reducer, with oil-bath gearing working synchronously.
Full open arc type discharging door can exhaust finished mixture
rapidly which effectively reduces mixing cycle.
5, multi-stage dust collecting method, different size of filler
will be collected and recycled to improve the utilization of raw
material.Bag house filter adopts DUPONT NOMEX material filtering
bags; high pressure compressed air impulse blowing system that will
be much more efficient to clean dust, which will meet the
environmental emission standards
