间歇式沥青拌和站冷料供给系统流量的标定方法

An Approach of Calibration of Aggregate Supply System of Asphalt Concrete Mixing Plant

以实例介绍间歇式沥青拌和冷料供给系统流量的标定方法和步骤,以确保冷料供给器按目标配合比准确供料,使沥青混合料的生产配比更加接近目标配比,保证拌和成品料的质量。

The cold feed bins of asphalt mixing plant should supply aggregates at a certain speed and in design proportion. In order to assure the supply accurately, the cold feed bins should been calibrated before construction. After calibration, every cold feed bin keeps stable volume respectively, controls design gradation from cold material, assures the quality of HMA and makes produce gradation be more close to design gradation.
