Variable Speed Aggregate Feeding: Frequency-controlled belt feeders provide accurate aggregate dosing according to the selected production recipe, ensuring compliance with international road construction specifications.
2. Twin Shaft Pugmill Mixer for Superior Mixing Performance
The heart of every WMM Plant is its Twin Shaft Pugmill Mixer, designed to produce homogeneous Wet Mix Macadam (WMM), Plant Mixed Base (PMT), Cement Treated Base (CTB) and soil stabilization materials.
Wear-Resistant Internal Liners: High-chromium wear plates and mixing paddles provide excellent resistance against abrasive materials such as granite, basalt and crushed stone.
Continuous Production: An optional 20 m³ discharge storage hopper allows uninterrupted plant operation during truck replacement, maximizing productivity and minimizing downtime.
Homogeneous Mixing: The synchronized twin shafts ensure uniform moisture distribution and excellent material consistency throughout the mixing process.
3. Advanced PLC Automation & Unlimited Recipe Management (Optional)
Our WMM Plant can be equipped with an advanced PLC control system, allowing operators to manage the entire production process through a user-friendly interface with a single touch.
Unlimited Recipe Storage: The control system enables unlimited storage of production recipes for different project specifications, including highway authorities, municipalities and international construction standards. All production data can be recorded and retrieved for quality control and traceability.
4. Versatile Mixing Solutions & Additive Integration
MBA Wet Mix Macadam Plants are designed for much more than conventional aggregate and water mixing. They can be configured to produce a wide range of stabilized materials required by modern road construction projects.
Cement Stabilization: Optional cement silo and dosing system for the production of Cement Treated Base (CTB) and other cement-stabilized materials.
Reclaimed Asphalt (RAP) Integration: Capability to incorporate reclaimed asphalt pavement (RAP) into the production process, improving sustainability and reducing material costs.
Bitumen Emulsion & Foamed Bitumen: Optional liquid binder injection systems for cold recycling, soil stabilization and foamed bitumen applications.
5. Containerized Design for Easy Worldwide Transportation
Both our mobile and stationary WMM Plants are engineered for efficient international transportation and rapid installation, making them ideal for projects worldwide.
Container-Friendly Design: Major plant components are designed to fit into standard shipping containers, reducing freight costs and simplifying overseas logistics.
Fast Installation & Relocation: Thanks to the modular bolted structure, the plant can be assembled, dismantled and relocated quickly, minimizing project downtime and maximizing operational efficiency.

Frequently Asked Questions About WMM Plants
Find answers to the most common questions about WMM Plants (Wet Mix Macadam Plants), including production capacity, automation, mixing technology, transportation and project-specific customization.
How does the WMM Plant ensure accurate aggregate dosing ?
MBA WMM Plants use frequency-controlled belt feeders, precision weighing systems and PLC-based automation to ensure accurate aggregate dosing. Production recipes can be stored and automatically recalled, providing consistent material quality that meets international road construction specifications.
How Are WMM Plant Prices Determined?
The price of a WMM Plant (Wet Mix Macadam Plant) is not fixed and depends entirely on your project’s technical requirements and production capacity. Key factors affecting the overall investment include the number and capacity of aggregate feed bins, whether the plant is stationary or mobile, the size of the Twin Shaft Pugmill Mixer, optional cement or liquid additive dosing systems, the level of PLC automation, and other project-specific equipment.
As a WMM Plant manufacturer, MBA provides customized engineering solutions and competitive quotations tailored to each customer’s production needs. Contact our team today to receive a project-specific proposal and the latest factory-direct pricing.
What Site Preparation Is Required for Installing a WMM Plant ?
Thanks to the modular and load-balanced design of MBA WMM Plants (Wet Mix Macadam Plants), extensive and costly civil works are generally not required. For stationary WMM Plants, simple reinforced concrete foundations designed according to the supplied foundation drawings are usually sufficient. For mobile or containerized WMM Plants, a properly compacted and level ground surface is typically all that is needed for fast installation.
After the order is confirmed, our engineering team provides free plant layout drawings, foundation plans and utility connection details, ensuring quick installation and efficient project execution.
Which Maintenance Points Are Most Important for Long-Term WMM Plant Performance ?
Routine maintenance is essential to maximize the service life and reliability of a WMM Plant (Wet Mix Macadam Plant). Daily inspections should include checking the bearings of the Twin Shaft Pugmill Mixer, seals, conveyor belt rollers and lubrication points to ensure smooth operation. Weekly maintenance should focus on conveyor belt alignment and tension, motor and gearbox connections, and the condition of electrical components.
Wear-resistant mixer liners, paddles and aggregate feed system components should be inspected regularly and replaced when necessary to maintain consistent production quality and minimize downtime.
How Many Operators Are Required to Run a WMM Plant Efficiently ?
Thanks to the advanced PLC automation system, an MBA WMM Plant (Wet Mix Macadam Plant) can be operated efficiently by a single operator from the control cabin. For continuous production, one additional loader operator is typically required to feed the aggregate bins, while another site worker may assist with general plant supervision and logistics. Under normal operating conditions, a team of three operators is generally sufficient to ensure safe, reliable and efficient plant operation.
