Mobile asphalt drum mix plant is a combination of mobile asphalt plant and continuous drum asphalt plant, integrating the core features of both. Its core working mode is: the drying and heating of cold aggregate and mixing of the mixture are completed continuously in the same drum. This design retains the advantages of flexible turnaround of a mobile plant and the high productivity of a continuous mixing plant.

This equipment is especially suitable for rural roads, low-grade highways, road maintenance and mountainous highways and other projects, which can efficiently match the construction needs of frequent site changes.

The whole set of equipment is divided into three core stages of the operation process, interlocking and fully automated:

Batching and Screening

Each feed bin is equipped with weighing hopper, adjustable gate and variable speed feeding belt. The oversize aggregates are filtered and the different sizes of aggregates fall into the feed belts in a set ratio and are transported via an inclined conveyor to the drying drums.

Drying and Mixing

Once the fuel is ready, the drying drum will be heated up to 120-180℃. Qualified cold aggregate, liquid asphalt and filler will be dried, heated and mixed simultaneously in the drum to ensure the homogeneity and temperature of the mixture.

Storage and Transportation

The finished asphalt mixture can be directly deposited into the storage silo for temporary storage, or can be directly unloaded into the dump truck for quick transportation to the construction site, avoiding the temperature loss caused by the secondary transfer.

Compared with traditional equipment, the advantages of this mixing plant are concentrated in 6 aspects, which directly hit the construction pain points:

Superior mobility, zero pressure for transiting

Adopting modularized design and chassis-type structure, this mixing plant can be transported directly by trailer without disassembling. Compact size can easily pass through narrow roads and reach remote construction areas such as mountainous areas, significantly reducing transit time.

Continuous Production, Efficiency

Aggregate drying, heating and mixing are carried out continuously, and the uninterrupted operation mode can realize the production of large quantities of asphalt mixture, which can efficiently match the progress demand no matter it is for small-area road maintenance or large-scale highway paving.

Automated Control, Zero Barrier to Operation

is equipped with an advanced intelligent control panel that supports three modes of operation: fully automatic, semi-automatic and manual. With real-time monitoring of mixing ratio, temperature and productivity, even novices can get started quickly, reducing labor costs and operating errors.

Compact design, small footprint and strong adaptability

The overall structure is streamlined and does not require a large hardened foundation, so it can be built directly on the narrow construction site, which is perfectly suited for space-constrained projects such as urban road reconstruction and road renovation in old neighborhoods.

Energy-saving and environmental protection, reducing operating costs

Urban Infrastructure

The compact size of the machine is suitable for flexible transit within the city, serving multiple municipal road reconstruction and sidewalk renovation projects at the same time, reducing interference with urban traffic.

Road Maintenance and Repair

can quickly move into the maintenance site and produce small batches of mix for pothole filling and pavement renovation, significantly shortening the maintenance period and reducing the length of traffic congestion.

Small and medium-sized projects

For small construction projects such as rural roads, neighborhood roads, industrial parks and other small construction projects, the equipment’s advantages of low investment and high return are particularly prominent.

Cold Mix Asphalt Production

In the temporary repair works without heating, or in the construction scenarios in low-temperature areas, it can be switched to the cold mix mode, which can flexibly adapt to the diversified needs.

Status of Infrastructure Construction in Africa: Mobile Mixing Plant Becomes a Rigid Solution

Africa is in the explosive period of infrastructure construction, especially the blossoming of projects such as connecting rural highways, upgrading urban road networks, and perfecting infrastructures in remote areas. However, the local scattered construction sites, complex terrain conditions (mountainous, Gobi mostly), weak transportation and logistics system, as well as the construction of unstable regional power supply and other issues, so that the traditional fixed asphalt mixing plant is difficult to adapt.

Mobile drum asphalt mixing plant with “mobile, easy to install, high efficiency and energy saving” core advantages, accurate solution to the construction pain points in Africa, become the local road construction “equipment”, but also China’s asphalt equipment to go overseas the core of the main models.

Benchmark case landing: practical application covering many countries in Africa

As a leading domestic asphalt mixing equipment company, ZOOMLINE has mature project experience and perfect service system in the African market, and its equipment application has covered many countries such as Mali, Kenya, Madagascar, Zimbabwe, Nigeria, etc., which is suitable for construction needs of different scales and terrains, and has left many benchmark projects.

In 2022, Zimbabwe launched an urban road upgrading project, and in response to the pain point of limited construction space in the urban area and the need for frequent transshipment, ZOOMLINE introduced 80TPH mobile drum asphalt mixing plant, which realized the simultaneous construction of multiple road sections, significantly shortened the construction period, and ultimately completed the refurbishment of the urban trunk road three months ahead of schedule.

During the same period, in order to solve the problem of infrastructure material transportation in remote areas, Nigeria introduced 40TPH model to produce asphalt mixtures on site, eliminating the cost of long-distance transportation and temperature loss of mixtures, and successfully assisted the local three rural highways to pass through, improving the travel conditions of local residents.

In 2025, Kenya focuses on improving the quality of county highways and deploys medium-sized mobile drum asphalt mixing plant of ZOOMLINE Machinery, which is adapted to decentralized construction sites in the county, taking into account the efficiency and cost; Mali, combined with the smaller scale of rural road construction and the characteristics of decentralized construction sites, decided to install a 20TPH model in December 2025, which is specifically used for construction and small-scale maintenance works of rural roads to further improve the local road network. Local road network.

Adaptation core: why is the mobile drum mixing plant suitable for the African market?

These successful application cases fully reflect the high adaptability of mobile drum mix plants to African construction scenarios, and the core advantages are focused on four points:

The equipment can be transported directly to remote construction sites by trailers without disassembling, which greatly reduces the transportation cost and the difficulty of transferring to other sites.

Secondly, the 20-80TPH multi-speed capacity can accurately match the demand of all scenarios from village road maintenance (20-30TPH) to high-speed construction (60-80TPH), avoiding the waste or insufficient capacity.

Thirdly, the equipment adopts integrated design, which is easy to install and does not require complicated foundation hardening. Even in areas with unstable power supply, it can be paired with a standby generator for normal operation to ensure construction continuity.

In addition, the energy-saving and consumption-reducing features also fit the current situation of energy constraints in the African region. The advanced burner system can reduce fuel consumption by 15%-20%, helping local contractors to further control operating costs.

The equipment is equipped with multi-cyclone + bag double dust removal system as standard, and some models can be upgraded to pulse bag dust removal. The dust generated by mixing and drying is first captured by multi-cyclone dust removal to capture coarse particles, and fine dust is then filtered by the bag, the dust concentration can be controlled within 50mg/nm³, which meets the environmental standards of Africa, Southeast Asia and other regions around the world. The system is equipped with a dust recovery device, and the recovered dust can be reused in the mixing ratio, realizing the reuse of resources and reducing construction costs, and the dust removal program can be customized according to the local environmental protection policy.

The equipment supports long-time continuous operation for 24 hours. It adopts continuous mixing design with thickened wear-resistant drum liner, high-temperature-resistant burner and stabilized hydraulic system, and its capacity covers 40-120TPH to meet the demand of high-intensity construction. Specially optimized for the harsh environment of high temperature and sand, the drum is made of high-temperature resistant material, which can withstand long-term operation at 120-180℃; the electrical control system is equipped with dustproof and waterproof housing, and the dustproof cover is added to the feed bin and conveyor to reduce the erosion and wear of the equipment. In the high temperature environment of over 40℃ in Africa, it can work stably for more than 72 hours continuously with very low failure rate.

The equipment adopts modular integrated design, and the core components are all debugged before leaving the factory, so there is no need to dismantle the equipment on site, and it can be installed by ordinary construction workers without the need for a professional team. Only need the crane to complete the simple splicing and fixing, connecting water and electricity fuel can be commissioned: 20-30TPH model, 2-3 people with 4-6 hours to complete, can be put into operation on the same day; 40-80TPH model, 3-4 people with 8-12 hours to complete. Manufacturers provide detailed installation instructions and video guidance, can also be arranged on-demand technical personnel to visit the guide.
