The multifunctional single / compound doped particle lignin and basalt fiber feeding machine comprises a fiber weighing and storing system, a fiber conveying system, a fiber fluffing system and a control system; the fiber weighing and storing system comprises a basalt fiber storage bin, a particle lignin fiber storage bin, a bin level gage, a fiber metering chamber and a drain valve; the fiber conveying system comprises a spiral conveyor, an air blower, a discharging opening and a matched pipeline; the fiber fluffing system comprises a fiber fluffer; and the control system comprises a fiber quantitative discharge control system and an air blower control system. According to the multifunctional single / compound doping particle lignin and basalt fiber feeding machine and the use method of the invention, the mixing requirements of a asphalt mixture mixing plant on single mixing and compound mixing of basalt fibers and granular lignin fibers are met, the requirements of the asphalt mixture mixing plant on manual operation are reduced, the operation difficulty and mixing error rate of the mixing plant are reduced, and the mixing efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of asphalt mixture for roads, and relates to a multi-functional single-mix granular lignin and basalt fiber feeding machine and a use method. Background technique [0002] According to a large number of experiments and engineering practice, the incorporation of fibers can have a certain positive impact on the performance of asphalt mixture. At present, granular lignin fiber has been widely used in SMA graded asphalt mixture, and basalt fiber is also used in the gradation of various asphalt mixtures. At the same time, compounding the asphalt mixture with specific grades can improve the optimization effect of asphalt mixture pavement performance on the basis of single fiber blending. [0003] At present, the fiber feeders supporting the asphalt mixing plant include granular lignin fiber feeder and basalt fiber feeder. This type of fiber feeder needs to be changed according to the type of fiber, which increase...
