Introduction: The main function of FX5000 fiber feeder is to cooperate with the production of asphalt mixing station, to realize the timing and quantitative release of all kinds of road fibers such as flocculent lignin fiber and polyester fiber according to the amount of engineering design, and make the road fibers dispersed in the asphalt mixture aggregate evenly, so as to improve the stability of the asphalt mixture aggregate. System composition of FX5000 fiber feeder: FX5000 fiber feeder is composed of storage bin, dispersing system, conveying system, metering system, feeding system, simple fault alarm system and so on. Working principle of FX5000 fiber feeder: According to the characteristics of the road fiber, the machine adopts the method of time and volume measurement. During production, the fiber materials to be put into the storage bin, the conveying system will transport the broken fiber materials to the metering system, the machine will blow the measured fiber to the mixing cylinder timely according to the set dosage and delivery time, to ensure the accuracy of the amount of added road fiber and dispersion in the mixed aggregate. The machine has a high degree of automation, workers need to ensure only that there is material in the warehouse during production, metering and delivery work can be completed automatically.
