Asphalt application process station during burner, can play a very stable results, and will achieve high efficiency function, the asphalt mixing plant burner and inspection schedule
Asphalt mixing plant burner and inspection schedule
To advance to the laboratory of residue detected heating value. After some time the use of heavy oil or residual oil, asphalt mixing plant to be inspected and scheduling combustor. Available Combustion gas analyzer confessed whether full combustion of the fuel, together with the drum and baghouse monotone check to see whether or greasy oil mist, to prevent fires and oil blocked. Oil on the atomizer with the build up of poor oil and increased punctuality thus be cleaned. When the use of residual oil, the oil outlet tank should be higher than the orientation of the bottom around 50cm, in order to prevent the accumulation of water and debris into the bottom of the tank fuel line. Before the fuel enters the burner 40 to be filtered with a mesh filter, a pressure gauge of the security of both ends of the filter to ensure excellent operation of the filter can be washed at discover and blocking. Further, after the operation, the switch should turn off the burner, and then heating the heavy oil off, or downtime when cold oil passage switching valve, washing with light oil passage, or otherwise difficult to constitute a poor oil incineration. Bitumen content, aggregate gradation and bitumen content of the Marshall test, aggregate gradation and Marshall experiment is an important principle of asphalt quality, therefore, next to the station and press the sampling frequency asphalt bitumen content, aggregate gradation and Marshall test is crucial. Detecting a frequency of 1-2 times per shift, to urge the asphalt mixing plant laboratory personnel and electronic article furnace experimental instrument Marshall affixed to the printed test reported as a useful basis of experimental data origin. Supervision sampling frequency is 20% of the asphalt mixing plant, or sent to the central laboratory supervision assay is qualified inspection center, and road specification data supplied degree of compaction testing. No data directly flash article asphalt temperature on the heating temperature of the bitumen and mineral aggregate and the mixing time, asphalt mixing machine, and therefore should be near to attach importance to the heating temperature Asphalt Temperature and mineral aggregate, comprising a drum temperature and solid hot mineral extraction temperature, then conjecture article asphalt temperature. Asphalt mixing time depends on the specific circumstances by the test mix confessed to uniformly wrap overlying bitumen aggregate degree, batch mixing machine production cycle of each disc should be less than 45s (during dry mixing time should be less than 5-10s) , modified bitumen and mixing time SMA mixture should be appropriately extended.
