LBNZ counter-flow integrated asphalt mixing plant

Energy saving | Stability | Environmental protection | Safety
NFLG's counter-flow integrated asphalt mixing plant is a new generation of high-proportion plant-mixed hot regeneration energy-saving and environmentally friendly asphalt mixing equipment newly developed by the company. Full heat exchange, special regeneration system design, regeneration addition ratio up to 70%, native regeneration integrated design structure, quick installation, recycled material automatically falls into the mixer, non-stick material, large finished product bin at the bottom, finished product material trolley travels in two directions; it can be realized with functions such as raw, large-scale regeneration, foamed asphalt, and cold addition of recycled fine materials.
01

Counter-flow heating of recycled materials has high thermal efficiency and low fuel consumption

02

Steel structure hot blast furnace has low noise and low maintenance cost

03

A large proportion of recycled materials is added, and the economic benefits are considerable

04

Fully environmentally friendly design

Cold aggregate bin

The belt feeder can be frequency-controlled according to output settings and ratio requirements.

The sand bin is equipped with internal vibration arch breaking and air cannon arch breaking devices, eliminating the need for manual digging of materials.

Configured with sound and light alarm function for material shortage.

Vibration screen

The vibration screen shell is covered with insulating rock wool for noise reduction and heat preservation.

The vibration motor directly drives the screen body, with high transmission efficiency, maintenance-free and long life.

Screening efficiency ≥95%, screen tension can be identified, easy to operate.

Hot aggregate bin

Each bin is equipped with a continuous material level meter and a temperature sensor is installed in the sand bin.

Configured with online sampling port, safe and convenient.

The discharge door is a long and short double door design with coarse and fine discharge functions.

Mixer

High-speed flexible synchronous drive, three-dimensional mixing, high mixing efficiency.

Wear-resistant blades and liners imported from Sweden, super wear-resistant.

Interfaces reserved for adding thermal regeneration, wood fiber, foam asphalt, etc.

Counter flow drying drum

The recycled material temperature is higher, the exhaust gas temperature is lower, energy saving and high thermal efficiency.

Heating with furnace hot air for uniform heating; waste heat recovery, energy saving and consumption reduction.

RAR addition ratio can reach up to 100%.

Intelligent CNC burner

The system intelligently adapts to the combustion modes of different working conditions and oil products, making it worry-free and efficient.

Patented technology for aggregate temperature measurement, one-button operation, self-adjusting parameters, easy operation.

Intelligent control scheme, accurate temperature control, stable combustion and low emissions.
