The process of setting up the mobile asphalt mixing plant mainly includes the following four parts: siting、planning and construction、relocate of the asphalt mixing plant and commissioning and start-up.
1.1 Siting of the mobile asphalt mixing plant
Site selection of mobile asphalt mixing plant should take both what effect the mobile asphalt mixing plant may brought to the neighboring regions and residents and economical factor into consideration. So, consider the following factors seriously:
1.Reasonable distance between the site of mobile asphalt mixing plant and construction site of bituminous pavement. Sites near the middle of construction section should be the best choices. Besides, convenient transport which could save the cost of convey finished materials, meanwhile, convenient water and electric sources should also be planned carefully.
2.Proper distance from residential area and ecological area. This could reduce the influences of noise and smoke, which could help build good corporate image.
3.There are enough flat places for the location of mobile asphalt mixing plant, the storage of finished products and the drive of the vehicle.
1.2 Planning and construction of mobile asphalt mixing plant
To make scientific and rational plans, the following factors have to be took into consideration seriously.
1.The position of mobile asphalt mixing plant.
The mobile asphalt mixing plant should be placed at the solid area. If there are requirements that mobile asphalt plant foot should be built based on the cement concrete, make sure there are enough bear capacity.
2.The planning and construction of material yard.
Material yard should be parted according the different bituminous concrete mixture and the spacing design should be reasonable. Sorting and segregating the stockpiling zones clearly in case any of them were mixed together which would affect the working schedule and product quality. The roadbed of material yard should be solidified to avoid the slip and sink of the vehicles.
3. Plan ahead to avoid the congestion of vehicles used to convey raw materials, finished materials and so on and improve driving safety.
4.Make sure there are suitable spaces between different parts and equipments. For instance, the diesel tank should be kept in the safe distance from the heat producer and source of ignition; and the asphalt tank should be near the electronic weighing system of the asphalt mixing plant as much as possible.
1.3 Relocate of the asphalt mixing plant
Generally speaking, the speed is a key factor in the process of setting up a mobile asphalt mixing plant. How to relocate the asphalt mixing plant economically and rapidly?
1.A complete and detailed plan based on the asphalt mixing plant features is necessary. It rules the order to relocate the asphalt mixing plant.
2.Arrange professional work team. Their engineering level affect the disassemble progress directly.
3.Security measures should be adopted to make sure there are none gaps and omissions.
1.4 The commissioning and start-up of asphalt mixing plant
After finished setting up the asphalt mixing plant, it’s time to commissioning the equipment.
Firstly, test the pipe pressure. Make sure there no leakage at the commissures and detail places between the heat transfer oil and bitumen pipelines. If there are any leakage problems, deal with it immediately and try it again until each part works normally.
Then, make sure all the equipments are in good condition through total preventive maintenance and reliability tests of power supply system and control system. In the wake of test runs done to check the validity of control system and the motor shift with pointing control, the whole asphalt mixing plant could be operated for a test run with automatic control.
At last, after experiment on and calibrate the accuracy of electronic weighing system, there are screen tests and grading design before produce with specimens.
The asphalt mixing plant could go in to regular operation when the finished products proved to be qualified.
