Mobile Asphalt Mixing Plant

Mobile asphalt mixing plant is a flexible transfer, rapid installation and commissioning of the asphalt mixture production equipment, the core features of the integrated design, the cold material supply, drying and mixing, dust removal, control and other systems integrated in the movable chassis, without the need for complex foundation construction, to adapt to the different construction sites of the rapid switch. According to the different mixing methods, it is mainly divided into two main types:

Mobile Drum Mix Asphalt Plant

Core Composition: It consists of cold material supply system, drying drum, dust removal system, asphalt supply system and control system, with a compact structure and a small footprint.

Workflow: The loader sends cold aggregate of different specifications into the cold hopper, which is transported to the vibrating screen through the belt conveyor to screen out the qualified aggregate of ≤40mm; Qualified cold aggregate and asphalt are sent to the dry mixing drum through belt conveyor and pipeline respectively to complete heating, drying and mixing in the drum to form uniform asphalt mixture; The dust generated in the mixing process is sucked into the dust removal system to avoid environmental pollution; The finished asphalt is sent by bucket elevator to the storage drum for temporary storage and insulation, waiting for the engineering truck to transfer to the construction site.

Core Advantages: Convenient to move, affordable and easy to operate, suitable for small and medium-sized roads, low-grade highways and emergency repair works.

Mobile Asphalt Batch Mix Plant

Core features: The components are basically the same as those of the Stationary asphalt mixing plant, the difference lies in the increase of the metering system, which retains the high-precision advantage of intermittent mixing and the higher degree of automation.

Workflow: Cold aggregate is sent to the drying drum by belt conveyor for heating and drying after initial weighing, and the dust and moisture generated in the process are treated by bag filter; Hot aggregate is sent to vibrating screen through elevator, classified according to specifications and deposited into storage hopper, and then sent to weighing device for secondary weighing according to preset proportion in sequence; Mineral powder is fed into the temporary storage hopper through elevator and then weighed, and asphalt is fed into the weighing device through pipeline to be weighed; After weighing, the aggregate, mineral powder and asphalt will be fed into the twin-shaft mixer in turn, and after reaching the set time, the mixture will be discharged into the finished product silo, and finally loaded into the construction truck for transportation.

Core Advantages: The mixture is evenly mixed and the finished product is of high quality, which is suitable for highway, airport runway, city main road and other projects with strict requirements on asphalt quality.

The scale of different projects, quality requirements, site conditions vary, the choice of suitable mobile asphalt mixing plant is the key to improve efficiency. The following are ZOOMLINE popular models and applicable scenarios for the reference of the engineering side:

T-type Mobile Batch Mix Asphalt Plant

Applicable scenes: large infrastructure projects, such as national highways, cross-river bridges, water conservancy projects supporting roads, etc., with both high productivity and energy-saving, able to cope with high-intensity construction needs.

In the continuous upgrading of infrastructure construction, construction scenarios increasingly diversified today, mobile asphalt mixing plant with flexible, efficient, low-cost core advantages, gradually replace some of the traditional stationary mixing plant, become the mainstream equipment in the field of road and bridge construction.

It does not require a stationary site, can be quickly deployed to accurately match the construction needs of different scales and different environments, the following are its three core application scenarios.

Remote and temporary construction sites: cracking the transportation problem

In the rural highway construction, bridge erection in mountainous areas, remote industrial parks and other projects, the construction site is often far away from the urban core, far from the traditional Stationary asphalt mixing plant.

In the traditional mode, ready-mixed asphalt needs to be transported over long distances, which not only generates high logistics costs, but also may lead to asphalt mixture cooling and segregation due to the long transportation time, affecting the quality of the project.

Mobile asphalt mixing plant can be directly stationed at the construction site, in situ production of asphalt mixture of the required specifications, eliminating the transportation link from the source. Not only reduces construction costs, but also ensures the stability of asphalt quality, infrastructure construction in remote areas to provide an efficient solution.

Small and medium-sized projects

To adapt to the flexible construction needs of urban feeder road maintenance, paving of internal roads in the community, daily maintenance of bridges, township road renovation and other small and medium-sized projects, there is a small amount of work in general, the construction cycle is short, site constraints and other characteristics.

Large-scale Stationary mixing plant has overcapacity, complicated installation and dismantling, and high cost, which makes it difficult to adapt to this kind of fragmented projects.

The mobile asphalt mixing plant is compact, setup convenient, can flexibly adjust the output according to the actual demand of the project, and does not need to occupy the site for a long time. After the construction is completed, it can be quickly withdrawn and moved to the next site, which effectively shortens the project cycle and reduces the comprehensive construction cost of small and medium-sized projects.

Emergency repair and quick turnaround projects: seize the construction time

Highway pothole repair, road subsidence repair after heavy rainfall, emergency renovation of municipal roads and other projects, the construction time requirements are extremely high, once the delay may affect traffic or even lead to potential safety hazards.

Traditional stationary mixing plant installation and commissioning takes weeks, simply can not meet the emergency needs.

Mobile asphalt mixing plants can be quickly transferred to the construction site by truck or trailer, and can be installed and commissioned within a short time after arrival. The timely supply of qualified asphalt mix ensures that the emergency repair works progress quickly, minimizes traffic disruption time and provides a key guarantee for the timely delivery of the project.

The choice of mobile asphalt mixing plant or stationary asphalt mixing plant, the core depends on the project scale, construction cycle, site conditions and other factors, the core differences between the two compared to the following:

Mobility and Flexibility

Mobile asphalt mixing plant: easy to migrate, fast installation and commissioning, suitable for frequent changes in the site, short-term projects, remote projects, can significantly save the site and time costs;

Stationary asphalt mixing plant: the location of the Stationary, the migration needs to be dismantled and reassembled, suitable for long-term, large-scale Stationary site projects, installation and dismantling time-consuming and laborious. Stationary asphalt mixing plant: Stationary location, need to be dismantled and reassembled for relocation, suitable for long-term, large-scale Stationary-site projects, time-consuming and labor-intensive installation and dismantling.

Cost and Investment

Mobile asphalt mixing plant: lower initial investment, no need for long-term site rental and complex foundation construction, can be constructed in close proximity to reduce transportation costs, suitable for enterprises with limited budget and multi-project operation;

Stationary asphalt mixing plant: high initial investment, large-scale equipment, complex structure, but with the scale effect, suitable for high-yield, long-term production of large-scale projects, long-term operating costs are more advantageous.

Capacity and Application Scenarios

Mobile Asphalt Mixing Plant: the capacity is mostly small and medium scale (20-320 tons/hour), suitable for small and medium-sized highways, maintenance projects, emergency projects, flexible adjustment of capacity to meet project needs;

Stationary Asphalt Mixing Plant: higher capacity, suitable for large-scale, continuous production, suitable for large-scale highways, airports, urban road networks and other long-term infrastructure projects.

Clear project scale and capacity requirements

Small-sized project (rural highway, community road): choose 40-90t/h capacity models, such as super batch type mobile asphalt mixing plant;

Medium-sized project (city main road, county highway): 60-200t/h capacity can be, T-type intermittent or super drum type are applicable;

Large-scale projects (highway, airport runway): give priority to high-capacity models above 200t/h to ensure adequate supply of mix.

Selection of mixing type according to quality requirements

High quality requirements for asphalt (such as highways, airports): choose intermittent mobile mixing plant with high mixing uniformity and precise grading control;

Ordinary road or emergency project: drum type mobile mixing plant is more cost-effective and can meet the basic construction needs.

Considering the site and environmental conditions

Narrow site or need to move frequently: choose fully mobile design models, such as super intermittent mobile asphalt mixing plant;

Strict environmental protection requirements (construction around the city): give preference to equipment equipped with baghouse dust removal system to reduce dust pollution.

Evaluate the late service and warranty

Choose the brand with perfect pre-sale, sale and after-sale service, such as ZOOMLINE provides 15 months warranty period, free replacement of quality problematic parts during the warranty period, lifelong technical support, 7×24 hours after-sale hotline, 1 hour response to faults, and 24 hours to solve common faults, to ensure the stable operation of the equipment.

Site selection is directly related to the mobile asphalt mixing plant's production efficiency, operating costs and environmental compliance, need to focus on the following four points:

Construction Site Distance

Combined with the paving temperature of asphalt mixture and transportation economy, the mixing plant and the construction site distance is recommended to be controlled within 80 kilometers, the maximum of 100 kilometers, to avoid temperature loss of the mixture to affect the construction quality, while reducing transportation costs;

Convenience Of Raw Material Supply

Asphalt production requires a large amount of sand and gravel, mineral powder, asphalt and fuel oil (heavy oil/natural gas), the site selection needs to be close to the raw material supply, to ensure timely transportation of raw materials to reduce the cost of procurement and transportation;

Geological Conditions

avoid faults, landslides and other geological disaster risk areas, avoid water at the bottom of the site, sand and other unstable terrain, reduce foundation treatment costs, to ensure the stability of the equipment operation;

Peripheral Environment

dust and noise will be generated by the operation of the equipment, and the site selection should be far away from schools, residential areas, hospitals and other sensitive areas, in line with the requirements of environmental protection control, and reduce environmental disputes.

The mainstream capacity of the plant covers 10-320t/h, which can be flexibly selected according to the actual daily output, duration and construction intensity of the project.
Among them, 10-80t/h small equipment is compact and convenient for transfer, suitable for short-term, decentralized projects such as rural road repair, small municipal projects, etc., which can enter the site quickly and occupy a small site;
90-150t/h medium-sized equipment takes into account the capacity and mobility, which is suitable for medium-sized projects such as county highway reconstruction, park road construction, etc.;
200-320t/h large-scale equipment adopts high-efficiency mixing system and continuous feeding design, which has a high capacity and high mobility.
The large-sized equipment adopts efficient mixing system and continuous feeding design, with stable production capacity and significant scale advantages, suitable for highways, large infrastructure projects and other scenarios that require continuous production for a long time, which can effectively guarantee the construction progress.

Yes, it can be used in remote areas without water and electricity!
For the construction pain point of remote areas without external water and electricity, some models of mobile asphalt plant are specially equipped with independent diesel power generation system, which can independently provide the power needed for equipment operation without relying on external power grids;
At the same time, the equipment is equipped with its own water storage device, which can satisfy the water demand of mixing, dust removal and other aspects, truly realizing “normal operation without external water and electricity”.
In addition, the equipment adopts modular structure design, reasonable weight distribution, convenient disassembly and assembly, and can be transported to mountain, Gobi, countryside and other complex terrain areas by trailer, and the machine body has good stability to adapt to bumpy sites, high and low terrain and other harsh construction environment, so that it is suitable for all aspects of construction needs in remote areas.

The number of daily operation and maintenance personnel is reasonably configured according to the capacity and model of the equipment to ensure efficient and safe operation.
Small equipment (20-150t/h) requires 3-6 people per shift, and the core team includes a supervisor, 1-2 control room operators, and 2-3 on-site maintenance personnel, with the supervisor co-ordinating the operation process and checking for safety hazards, the operators being responsible for the starting and stopping of the equipment, the parameter adjustment and data recording, and the maintenance personnel focusing on the operation flow, and the maintenance personnel on the startup and shutdown, parameter adjustment, and data recording. The operator is responsible for starting and stopping the equipment, parameter control and data recording, and the maintenance personnel focus on real-time inspection and simple troubleshooting of key parts such as feed inlet, mixing cylinder, and discharge outlet.
large-scale equipment (more than 200t/h) requires 6-8 persons per shift due to higher production capacity and a more complex system; on the basis of the staffing of the small-scale equipment, 1-2 professional maintenance personnel are added to the staffing of the small-scale equipment, focusing on the inspection and maintenance of the core components of the dust collection system, power generation device, and hydraulic system to ensure the continuous and stable operation of the equipment. Maintenance, to ensure the continuous and stable operation of the equipment, to avoid affecting the production progress due to the failure of the components.

Environmental protection can be ensured by both equipment selection and technology configuration to meet the current construction environmental protection requirements.
First of all, give priority to the models equipped with bag-type dust removal system or water-type dust removal system, the bag-type dust removal can efficiently filter the dust generated in the process of mixing and feeding, with a filtration efficiency of more than 99%, while the water-type dust removal realizes the purification of dust by spraying down the dust, and both modes can ensure that the concentration of the dust emission meets the local environmental protection standards and avoid dust pollution; first of all, the bag-type dust removal system can be used for the dust removal system.
Secondly, the selection of equipment models with low fuel consumption and high combustion efficiency, together with advanced exhaust gas treatment devices (e.g. exhaust gas purifier, denitrification device), can effectively reduce the emission of carbon monoxide, nitrogen oxides and other harmful gases.
At the same time, some of the high-end models are equipped with sound-proof enclosure and vibration-damping device, which can reduce the noise pollution during the operation of the equipment, and satisfy the requirements of environmental protection acceptance of the worksite in all aspects.
