DHB60 Drum Asphalt Mixing Plant With Mineral Powder Technical Specifications

1. The technique request about productivity

It can be made clear that the productivity of asphalt mixing plant is that under the standard conditions, it must fulfil the requirements as below simultaneously:

(1) Environment temperature:20℃, standard atmospheric pressure;

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

(3) The temperature of the hot mixture <160℃;

(4) The mixture is of middle size, the density of stone material≥ 1600kg/m3;

(5) The content of sand material in mixture <35%;

(6) The product capability includes asphalt;

(7) The stone aggregate must accord with the proportion requirements of national technical specifications.

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

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

(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℃±5℃. The using asphalt is normal asphalt without any other additives.

2. Detailed requirements for the oil quality:

(1) light oil: diesel oil, thermal value should be no less than 46055kJ/kg.

(2) For the heavy oil burner, application of heavy oil must accord to related quality requirements. The user must purchase required oil in accordance with relevant standard, and ask the oil supplier to provide related quality certificate (such as test report, etc); it should be easy for burning and pulverization. It is prohibited to use corrosive fuel and other abnormal oil. (if the burner is damaged because of quality problem of diesel or heavy oil, all the related damaged spare parts and maintenance cost will be afforded by users themselves)
