Adopting counter flow heating method results in higher heat exchange rate, lower exhaust gas temperature, and lower energy consumption. The design structure of large diameter and long drum allows the recycled material to be gently heated inside the drum, ensuring the discharge temperature while reducing the degree of asphalt aging. Special flexible feeding blades and self-cleaning chains are installed inside the drum, which can effectively reduce the adhesion of the drum wall and blades, and enhance the self-cleaning ability of the drum.
Multi point safety detection + linkage control, fast air door closing protection device + automatic fire shut-off function.
The main building is designed with fully sealed negative pressure, without dust overflow. The regenerated flue gas adopts secondary combustion, meeting environmental emission requirements.
Stainless steel plates are pasted inside the regeneration storage silo and regeneration dosing hopper, which has good anti sticking effect.
The hot air stove is equipped with a specially designed ceramic fiber layer, which is light weight, has a low heat transfer coefficient, and is easy to maintain. By introducing low-temperature clean exhaust gas and mixing it with the hot gas flow of the burner, the temperature of the hot gas flow can be effectively controlled. Multiple temperature measurement points are installed on the furnace body, and the mixing air volume is automatically adjusted.
The mixing tank is placed on the side of the main regeneration building, using a large capacity mixing pot, flexible drive, and strong power. The dual mixing arm layout and spiral blade arrangement make the mixing efficiency higher. The discharge door adopts a rotating structure design, with fast discharge speed.
What are the capacity differences between the LBRN3020 and LBRN4030 models?
The LBRN3020 offers an original rated productivity of 240 t/h and a maximum productivity of 360 t/h. The LBRN4030 is designed for higher capacity operations, providing an original rated productivity of 320 t/h and a maximum productivity of 468 t/h.
How does the counter flow heating drum reduce asphalt aging?
The counter flow heating drum features a large-diameter and long-drum design. This structure allows the recycled materials to heat up gently and gradually inside the drum, ensuring proper discharge temperatures while protecting the asphalt from overheating and aging.
What environmental protection standards do these mixing plants meet?
Both models are highly environmentally friendly, featuring fully sealed negative pressure buildings to prevent dust overflow. The dust discharge concentration is kept at ≤20 mg/Nm³, and the blackness of emitted flue gas meets the Greenman Level I standard.
What safety features are integrated into the system?
The plants feature multi-point safety detection paired with linkage controls. This includes a fast-acting air door closing protection device and an automatic fire shut-off function to prevent hazards instantly.
How is material sticking prevented during the regeneration process?
To prevent material build-up and sticking, high-grade stainless steel plates are pasted inside the regeneration storage silo and the regeneration dosing hopper, ensuring smooth and consistent material flow.
What is the dosing accuracy for aggregates and binders?
Both models maintain strict static dosing accuracy: Aggregate is measured within ±0.2%, while Powder and Asphalt are measured within ±0.1%. The oil & gravel ratio accuracy is kept within ±0.3%.
