II,The technical index
1.    Capability (standard conditions):
2. The mixer rated mix capacity:1100kg/batch;
3. oil consumption(standard conditions): 6.5kg/t;

5. The hot mixture discharge temperature:130~160ºC(common asphalt)
6.The figure dimension:(L×W ×H)32×27×16m
7.The total installed power: 231.95kw
III, Technical specification
1.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,1 standard atmospheric pressure; local altitude should be under 1000m;
(2)The average humidity of Cold aggregate <5%
(3)The temperature of the hot asphalt mixture <160ºC
(4)The mixture is middle size, 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 should not include more soil and sundries. The cold aggregate supply should be continuous.
(8)The cold aggregate should not 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 be < 0.5%, the filler addition  should be < 8%,and the filler should not  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 150ºC±5ºC. The using asphalt is normal asphalt without any other additives.
2. The requirements for fuel:
A. Light oil: diesel oil,heat calorific power is no small than 46055kJ/kg;
B. The heavy oil:thermal value≥9600kcal/kg;
kinematic coefficient of viscosity at 50ºC≤180cst;
Mechanical impurity content ≤0.3%;moisture content≤3%;
C.The customer needs to purchase heavy oil according the oil quality standard, and require the oil supplier to provide oil quality essay or the correlative certificates. The using fuel must have well burning and pulverization capability. Forbid using kinds of causticity fuel or the products from unqualified oil producing factory. (All the burner damage or failure that caused by diesel or heavy oil quality problem, the correlative damaged spare parts and customer oneself should afford the repair expense.
