concrete cellulose fiber feeder for reinforced asphalt pavement

Introduction

FM 5000 cellulose 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.

System Composition:

FM 5000 cellulose fiber feeder is composed of PLC control system, storage bin, screw conveying system, electronic weighing system, dosing system, fault alarm system and other control systems. All parts of the equipment are installed on a single frame, which is convenient for lifting, transportation and field installation.

Working Principle:

According to the characteristics of granular or powdered asphalt modifier, the machine adopts electronic weighing method, add quantitative granular or powdered asphalt modifier to the asphalt mixture timely and accurately according to the engineering design flow. During production, the particles or powder asphalt modifier is poured into the hopper, the whole feeding process is carried out under the control of PLC program automatically after the hopper door is closed . The feeding screw conveying system transfers the asphalt modifier in the hopper, such as anti-rutting agent and lignin fiber particles and so on, to the weighing hopper for weighing, and then waits for feeding signal after weighing accurately. After receiving the feeding signal from the PLC control system, the discharging screw conveyor sends the asphalt modifier with accurate weight to the asphalt mixing cylinder through a two-stage blower immediately, to realize the mixing of asphalt modifier and asphalt aggregate, and finally dispersing it evenly into the asphalt mixture. There is always a certain amount of material in the warehouse, which is added to the metering system timely. So it goes around automatically.

Feature :

1. Wide application range: it is suitable for all intermittent asphalt mixing equipment of M5000 type and below.

2, Apply PLC program control and electronic weighing measurement, high degree of automation, accurate weighing, timely feeding.

3. On the electrical control, we design the electric interlock between the stone discharge (asphalt) signal and the pellet feeder, which can prevent the phenomenon of less addition, more addition and leakage effectively. Equipped with a concise fault sound and light alarm, convenient to find and deal with the fault timely. In addition, it is also equipped with special signal connection input to realize the linkage of control signals from various mixing machines at home and abroad, and can be connected to 24v-220v control voltage.

4. The discharging hole of the cellulose fiber feeder extends to the work chutes in the mixing cylinder, add a guide corner , and an external material bin can also be installed for instant feeding. To ensure that the asphalt modifier in the asphalt mixture aggregate fully and evenly dispersed, play the role of asphalt modifier in the asphalt mixture aggregate better.

5, The shutdown control button of cellulose fiber feeder can be connected to the mixing control room, can be shut down timely, easy to deal with the mix before  and after production. To prevent unnecessary feeding caused by the failure of the feeding machine or mixing station.

6. High metering accuracy: the conveying volume of asphalt modifier is adjustable from 1 kg to 40Kg each time, the metering accuracy is ±0.2%, and the calibration accuracy can reach ±0.05%.

7. Intuitive and convenient operation: the machine is equipped with IOP LCD screen and printing interface, which is convenient to set working parameters and display operating procedures and fault monitoring tips timely.

8.Flexible control: the machine can provide automatic and manual control mode, automatic control for normal production, manual control for production debugging, testing.

9.Easy installation: the equipment is assembled on a single chassis. During installation, simply connect the outlet of the feeding equipment with the oblique lifting blanking outlet of mixing equipment or air supply pipe of mixing cylinder, and then work synchronously with the mixing production after switching on the power supply.
