Introduction FM 7000 multipurpose fiber feeder is in order to cooperate with the production of asphalt mixing station, according to the engineering design flow, add quantitative granular or powdered asphalt modifier to the asphalt mixture timely and accurately, make asphalt modifier disperse in the asphalt mixture evenly, thus enhance the stability of the asphalt mixture, improve the paving asphalt roadbed quality, prolong the pavement service life. FM7000 Multi-functional feeding machine system composition: 1. Composition and function of feeding machine system: 1.1 Fan system: the fan adopts 12kw ultra-high pressure and small air volume fan, which ensures the rapid release of materials and distributed in the asphalt mixture aggregate evenly. 1.2 Weighing control system: for pellets, the weighing control system adopts a high-precision weighing sensor, which can weigh up to 30 Kg; for floc, it adopts three high-precision weighing sensors, which can weigh up to 16Kg.The sensor signal is processed by the regulating signal junction box and amplifier, and then the motor is controlled by PLC to achieve the accurate feeding effect. 1.3 Operation display system: the operating system is operated by the keyboard to display all kinds of data on the TD400 display screen. It could set the amount of material arbitrarily and display the amount of material each time through the keyboard full of Chinese or English interface, to monitor the system operation. 2. Main components of feeding machine: 2.1 Feeding system: 2.2kw feeding meter. 2.2 Air supply system: 12KW high pressure, low air volume air pump fan, air volume is 28 m /min. 2.3 Weighing control system: particle weighing system, flocculent weighing system and computer control system. Parameter Product Name Multipurpose fiber feeder Model FM7000 Measurement method automatic electronic weighing measurement Control Mode PLC control system Weight 1900kg Size 2400mm*1200mm*2200mm Power 15.5KW Rated voltage 380VAC
