Mobile Hot Mix Asphalt Plant For Sale

A mobile hot mix asphalt plant for sale is a type of road construction equipment that integrates cold aggregate supply, drying and screening, metering and mixing, dust removal and purification, and intelligent control functions onto a mobile chassis, enabling the production of hot-mix asphalt while on the move.
 

Main Types of Mobile Hot Mix Asphalt Plant:
- Drum Type:
Primarily composed of a cold aggregate supply system, an asphalt supply system, a drying and mixing drum, a dust removal system, a travel system, and a control system, it offers advantages such as a small footprint, ease of mobility, and low cost. It is commonly used in small- to medium-sized road or low-grade road construction projects.
- Forced Type:
Its components and workflow are similar to those of a stationary hot mix asphalt plant. The key difference lies in the addition of a travel system and the use of a forced mixer, which ensures thorough mixing of cold aggregate and asphalt, resulting in a high-quality finished product and a high degree of automation. It is primarily used in projects with stringent quality requirements, such as highways and airport roads.
 

Common Models and Parameters
- QLB Series:
With a production capacity of 10-80 t/h, it features a compact modular structure, a small footprint, easy transportation and relocation, and a low initial investment cost.
- The CMB Series:
With a production capacity of 40-120 t/h, it utilizes a mobile, continuous drum mixing system. It features a compact design, low initial investment, and easy operation.
 

Operating Principle
- Cold Aggregate Loading: A loader loads cold aggregate of varying specifications into the cold aggregate silo. A belt conveyor transports the aggregate to a vibrating screen. Qualified cold aggregate below a certain particle size (e.g., 40 mm) is then conveyed to the drying and mixing drum via a belt conveyor.
- Mixing and Drying: Simultaneously, asphalt is transported via a pipeline into the drum, where the cold aggregate and asphalt are mixed and dried to form a uniform hot mix asphalt mixture. Dust generated during the drying process is sucked into a dust collector.
- Finished Product Storage: A bucket elevator lifts the finished asphalt mixture into asphalt storage drums for temporary storage and heat preservation, awaiting transport to the construction site by dump trucks.
 

Features of mobile hot mix asphalt plant:
- Easy to Move:
The modular design features independent modules for each functional unit. The undercarriage folds and can be towed by a tractor or other similar vehicle, enabling quick relocation and is suitable for projects with multiple, dispersed construction sites.
- Fast Installation:
These mobile asphalt plants typically feature quick power connections and a foundation-free design. After relocation, wiring and plumbing are connected, and commissioning can begin. This reduces infrastructure construction time and costs, allowing for rapid commissioning.
- Efficient Production:
They integrate advanced production technologies, such as integrated vibrating screening, precise weighing, and three-dimensional mixing technology within the mixing tower. Sensors and bidirectional mixing blades ensure the uniformity and stability of the asphalt mixture, meeting the production requirements of various project scenarios.
- Environmentally Friendly:
Equipped with efficient dust removal systems, such as a gravity-fed and bag-fed dual-stage purification system, they effectively capture dust generated during production, ensuring emissions meet environmental standards. Some equipment features optimized designs for energy conservation and consumption reduction.
 

Mobile hot mix asphalt plant for sale improve construction efficiency, reduce labor costs, and ensure the quality of asphalt mixtures, making them indispensable equipment in modern road construction.
