2-stage bag filtering asphalt plant witth 5 cold feeders 180T
output under 3% moisture
(1)Raw cold aggregate shouldbe clean, without soil and sundries,
whose supply should be nonstop for continuous production.
(2)Average humidity(moisture content) of Cold aggregate <5%
(3)Temperature of the hot asphalt product <160°C
(4)Mixing cycle time 45S, with middle sized bitumen mixture ,
average density of stone material around 1650kg/m3
(5)Fine aggregate content in mixture <35%;
(6) Filler proportion in raw aggregate should not higher than 3%.
(7)Local altitude should be less than 1000m; Nominal ambient temperature for batching plant runing: around 20°C, standard atmospheric pressure;
(8)Quantity of oversize grain among cold aggregate should be
limited within reasonable scope; otherwise it will cause block and
reduce the aggregate supply capability.
(9)Water content in filler material should be < 0.5%, without
being conglomerated or caked, otherwise will cause material supply break and time delay and
affect output accordingly.
(10)The asphalt should be of favourable wrapping property during mixing, therefore aggregate would be
completely wrapped by asphalt; asphalt temperature should be
controlled in the scope of 150°C±5°C. The using asphalt is normal
asphaltthat free from dirt, stain, impurities; or other additives.
