Working principle

Using the principle of cumulative measurement of weighing sensor, the metering value is preset; the system runs automatically (the running signal is the discharging signal of the mixing device sanding weighing hopper); when the metering reaches the set value, the system automatically stops running, which can realize each Delivery and addition of fiber materials.

Control system and control form:

PLC programmable control, using flow and weighing secondary measurement methods, can achieve manual and automatic control.

Delivery form:

The high-pressure fan is used to feed the fiber material into the high-level discharge bin and then into the mixer.

Delivery effect:

It is quick and accurate, ensuring full dispersion before dry mixing and full mixing with the mixture.

Main Feature

1. Multi-purpose: It can transport flocculent and granular lignin fiber, polyester, polypropylene, polyacrylonitrile fiber and mineral fiber, anti-rutting agent and other floc, filament or granular materials to achieve multi-purpose.

2. Unique metering and control system: It adopts flow metering and closed-loop automatic control electronic weighing system, with high measurement accuracy, weighing accuracy of ±0.10%; large conveying capacity, material conveying capacity can be set between 3~30kg (times/batch) . Remote controlling can be achieved (optional).

3. Synchronization: The equipment runs synchronously with the asphalt mixing plant, and has the function of material shortage and feeding abnormality alarm.

4. Rapid material output: The material output adopts a unique wind conveying mechanism and scientific solid-gas ratio design, which makes the conveying fast, and ensures that the fiber material is sent to the mixer within 3 seconds, and the conveying height can reach 20 meters.

5. The high-position discharge device is adopted to effectively separate the conveying air from the fiber material, thereby reducing the adverse effect of the high-pressure air on the mixed material in the mixer.
