In the construction of asphalt pavement, the asphalt concrete mixing plant plays a key role. The performance of the asphalt mixing station and the working condition of the asphalt mixing station directly affect the quality of the asphalt mixture, which is related to the quality of the entire project and the quality of the entire project. progress. Therefore, the asphalt mixing station's control skills were increasingly leading at that time, and the technological content was increasing. This requires mechanical operators to continuously improve their operating skills, to meet the construction requirements, to ensure that the machinery works normally, to show its due effect, and to ensure the quality of the project. Ensuring project progress. So how can we ensure that the machinery works properly and fully demonstrates its due effect.
First of all, the operator should be proficient in the structure of each part of the concrete mixing plant and its working principle. On this basis, strictly control the production details, especially the metering system. Due to the quality of the metering work, it directly affects the asphalt mixture. Skill indicators.
Regarding the stone measurement system, it should be noted that:
(1) Adhere to each discharge door, open and closed action is active and agile;
(2) Each unloading port must be unblocked, and there must be no sediment to ensure that the stone can flow down quickly and evenly during the measurement;
(3) All discharge doors should be closed in time and sealed well, and there should be no leakage of materials at the end of single material measurement;
(4) The aggregate weighing hopper should be kept clean and free of foreign objects, avoiding stuck hoppers, and ensure that the aggregate weighing is completely suspended at all times;
(5) Each aggregate load cell must have a balanced preload, a common stress and a flexible induction.
Regarding the concrete mixing plant powder measurement system, we should pay attention to the following points:
(1) Adhere to the unblocking of the powder transportation pipeline, and there must be no obstruction;
(2) The feeder or valve must be tightly sealed at the end of the measurement; powder cannot be leaked;
(3) often remove dust and other debris from the powder measuring bucket to keep it clean;
(4) All metering systems must be sealed well to prevent the powder from being damp and agglomerated;
(5) The powder material must be completely discharged, and there must be no residual powder in the scale. The concrete mixing plant discharge door must be closed tightly.
