The technique request about capability

It can be made clear that the capability of asphalt mixing plant is that under the standard conditions; it must fulfill the requirements as below simultaneously:

(1)Environment temperature: 20°C,standard atmospheric pressure; Local altitude should be less than 2000m;

(2)The average humidity of Cold aggregate <5%

(3)The temperature of the hot asphalt mixture <160°C

(4)The mixture is middle size, cycle time 45S, the density of stone material in the mixture≥1600kg/m³

(5)The content of fine aggregate in mixture <35%;

(6) The filler proportion in the raw aggregate material should not higher than 3%.

(7)The cold aggregate must be clean, and it shouldn’t include more soil and sundries. The cold aggregate supply should be continuous.

(8)The cold aggregate shouldn’t include large quantity of oversize grain; otherwise it will cause jam and reduce the aggregate supply capability.

(9)The water content in filler material should < 0.5%, and the filler shouldn’t have conglomeration, agglomeration, otherwise it will cause material supply break and time delay accordingly influence the capacity.

(10)The asphalt should be with well wrapping capability, during standard mixing circle, the aggregate should be completely wrapped by asphalt; the asphalt temperature should be controlled in the scope of 150°C±5°C. The using asphalt is normal asphalt without any other additives.

(11) Other aspects that will influence the producing capability:

1. under special environment, the environment condition or the different aggregate character will cause the obvious various capabilities.

2. the output of drying drum must include the quantity of hot aggregate flow and recycled filler.

3. when using the screen net, the capability may be reduced because of the using mesh size, aggregate supply and the adopted prescription.

4. the output of the mixer will vary subject to many specifications, like the aggregate supply, aggregate character and size, the wrapping character between asphalt and aggregate, quantity of asphalt and filler, mixing temperature etc.
