* aggregate are conveyed by frequency conversion control belt,ensuring accuracy of primary batching.
* Warning device and arch-breaking device efficiently prevent material shortage and jam. The operation is stable and efficient.
* A complete set of hard-tooth reducer has compact structure,ensuring high transmission efficiency, low failure rate and convenient maintenance.
* German technology, inertia dedusting combined with pulse bag filter dedusting,dust emission less than 50mg/N㎥, environment protection. *Over temperature protection system, double protection: the cold air valve opens automatically when the exhaust temperature is high, and the burner automatically closes when the exhaust temperature is too high.
3. Drying system
* The scraper inside the drying drum is made of high temperature resistant and wear-resistant material. The material curtain is distributed evenly,ensuring sufficient heat exchange and long service life.
* Low-pressure atomization technology, mechanical auxiliary atomization, adjustment ratio up to 1:10, suitable for a variety of fuels (diesel, heavy oil, natural gas), low noise.
* Four-wheel friction driving with high efficiency and stable performance.
4. Hot elevating system
* The elevator is of double-row plate chain with low noise, stable performance and long life.
* The bucket is made of low-alloy high-strength structural steel with wear-resistant lath at the edge. Build-up welding technology make it solid and stable with long life.
* Independently developed twin-shaft linear screen, vibration motor and horizontal twin-shaft (eccentric shaft) design make ensure that operating is efficient,screen replacing is fast and convenient,service life is long, and bearing maintenance exempt.
* Overflow design, triple guarantee: hot bin level indicator ensures accurate monitoring; overflow pipeline ensures automatic flow-off when the material is full; oversized-material chute ensures the flow-off of the aggregate when the specification is off-standard.
6. Weighing system
* The aggregate scale is tension-sensor accumulative weighing, with the function of splash error automatic correction, for large model it adopts the way of double aggregate scale synchronous weighing, the accuracy is ± 2.5%.
* The filler scale is three-point tension-sensor accumulative weighing, the accuracy is ± 2%.
* The bitumen scale is three-point tension-sensor accumulative weighing, with secondary weighing ,the accuracy is ± 2%.
* Horizontal twin-shaft mixer, lining board and mixing blade is made of high-strength wear-resistant Nickel alloy with long service life.
* The connecting rod turnover type discharging door opens and closes flexibly without jamming.
* The end product storage bin has heat preservation function. When the ambient temperature is 15-25 ℃, the mixture temperature decrease ≤ 5 ℃ within 12 hours.
8. Control system
* The PLC-control cabinet with Siemens parts realizes automatic, semi-automatic and manual control. It has the functions of formula input and storage, splash error automatic correction, parameter adjustment, scale calibration, bitumen aggregate ratio dynamic tracking, automatic failure diagnosis, automatic alarm and data printing.
9. After-sale service
* Modular design for convenient and fast installation, maintenance, relocation and transportation.
