The core features of a mobile ready mix concrete batching plant are modular design, ease of relocation, and rapid commissioning. At the same time, they must meet the core functions of concrete production (batch, mixing, metering, etc.). Their structure and functionality must be designed around the dual requirements of portability and production reliability.

I. Core Structural Components
The structure of a mobile concrete batching plant must balance disassembly/foldability with integration, primarily comprising the following components:
1. Mixing Main Unit System
- Core Equipment: A twin-shaft forced concrete mixer is typically used (small and medium-sized units typically have a capacity of less than 1.5 m³, while large units can reach 2-3 m³). This unit is suitable for various concrete grades (dry, hard, and plastic), achieving high mixing uniformity and efficiency.
- Auxiliary Design: The main unit is equipped with a hydraulic door opening device (to control discharge), a motor/reducer (to drive the mixing shaft), wear-resistant liners, and mixing blades (consumable parts for easy replacement). Some units also feature an automatic lubrication system to reduce maintenance.
2. Material Storage System
This system is used to store concrete raw materials (aggregates, powders, and liquids) and must meet the requirements of compactness and resistance to segregation and moisture:
- Aggregate silos: These are typically foldable or modular silos (2-4 silos for sand, gravel, etc.), with a capacity of 10-30 m³ per silo. Each silo is equipped with a pneumatic gate at the bottom for controlled discharge, and some are equipped with a vibrator to prevent blockage.
- Powder silos: For cement, fly ash, and other materials, these are enclosed silos (10-50 t capacity), equipped with a level meter to monitor storage levels, a pneumatic or electric arch-breaking device to prevent clumping, and a top dust removal port for connection to a dust collector.
- Liquid Storage: These include water tanks (5-20 m³ capacity) and admixture tanks (1-5 m³ capacity), both equipped with level meters and made of corrosion-resistant materials (admixtures are often acidic or alkaline).
3. Material Conveying System
Connecting the storage and metering/mixing stages, it requires "short-distance, foldable" features suitable for mobile scenarios:
- Aggregate Conveying: An inclined belt conveyor (foldable, 5-10m in length) transports aggregates from the silo bottom to the aggregate weighing scale. The belt has side guards to prevent spillage and end sweepers.
- Powder Conveying: A screw conveyor (horizontal/inclined, 150-200mm diameter) conveys aggregates from the silo bottom to the aggregate weighing scale, with a strong seal to prevent dust.
- Liquid Conveying: A water pump and an admixture pump (corrosion-resistant) transport liquids via pipelines to the corresponding metering devices.
4. Metering System
To ensure the accuracy of concrete mix proportions (a core quality requirement), high precision and anti-interference are required:
- Aggregate Measuring: A single scale or split scales (depending on the silo) utilizes sensor weighing (accuracy ±1%) and is equipped with a pneumatic discharge door (discharging to the main machine). Powder Metering: Independent scales (cement and fly ash can be shared or separate), with an accuracy of ±0.5%, and sealed to prevent powder leakage.
- Liquid Metering: Separate scales (or flow meters + control valves) for water and admixtures, with an accuracy of ±0.5%, and temperature control (water heating in winter).
5. Control System
Integrated Operation Center, Adaptable to Mobile Convenience:
- Hardware: Portable control cabinet (with touch screen + physical buttons) or integrated operation console, built-in PLC control system (core logic control), and printer connection for printing mix ratio sheets.
- Functions: Automatic/manual switching, mix ratio presets and modifications, production data recording (output, mix ratio, time), fault alarms (such as metering deviation and motor overload), and partial remote monitoring support (4G/Bluetooth).
6. Mobility and Support System
The core structure of the mobile machine determines its transportability:
- Chassis: Tractor-type (with tires, suitable for truck towing) or self-propelled (tracked/tire chassis, self-powered), suitable for road transport (width ≤ 2.5m, height ≤ 4m).
- Support: Hydraulic outriggers (4-6) support the machine body during operation to ensure stability (to prevent shaking during mixing that could affect metering accuracy). The outriggers have a leveling function to accommodate uneven surfaces.
7. Auxiliary Systems
Ensuring production continuity and environmental friendliness:
- Dust Removal System: Pulse dust collector (connected to the top of the powder silo and the main machine outlet) filters dust (emission concentration ≤ 30mg/m³).
- Cleaning System: High-pressure water pump + piping for cleaning the main machine, weighing scale, and discharge port. Wastewater can be collected (in a small sedimentation tank).
- Power System: If there is no power grid on site, a diesel generator (50-150kW) can be used to power the entire system. Safety devices: Emergency stop button, guardrails (on both sides of the conveyor belt), and grounding protection (to prevent electrical leakage).

II. Core Functional Requirements
Based on the structural design, the mobile ready mix concrete plant must provide the following functions:
1. Concrete Production
Complete the metering, dosing, mixing (mixing time adjustable from 15 to 90 seconds) of aggregate → powder → liquid according to the preset mix ratio, and unload to produce qualified concrete (strength, slump, and other indicators meet the standards).
2. Quick Site Transfer and Production
- Transfer: The plant can be towed or moved independently, suitable for short-distance transportation between construction sites (≤50 km), with a disassembly/folding time of ≤2 hours.
- Production: Upon arrival at the site, the outriggers are secured, piping/circuit connections are connected, and commissioning is complete. Production can begin within 1-2 hours (much faster than the several days required for a stationary concrete batching plant).
3. High-Precision Metering:
The metering tolerance for all materials must meet national standards (e.g., ±2% for aggregates, ±1% for cement) to ensure stable concrete properties such as strength and durability.
4. Adaptability and Reliability
- Environmental Adaptability: Operates in dusty and humid environments ranging from -10°C to 40°C (some with insulation/heating).
- Terrain Adaptability: Outriggers can adjust within a ±5° range, adapting to uneven construction sites.
Continuous Operation: Continuous production for ≥8 hours per run (depending on storage capacity).
5. Environmental Protection and Safety
- Environmental Protection: Dust emissions ≤ 30mg/m³, noise ≤ 85dB (controlled by soundproofing and vibration damping).
- Safety: Emergency shutdown response time ≤ 1s, and protective devices (such as conveyor belt guards) automatically activate while the equipment is running.
6. Maintenance
Key components (mixing blades, liners, and sensors) are easily disassembled and replaced. The control cabinet features fault diagnostics for quick problem location, and centralized lubrication points for easy maintenance.

The core logic of the mobile ready mix concrete batching plant is "maximizing mobility while ensuring the quality of concrete production." Its structure achieves convenient transfer through modular and folding design, and its functions focus on "rapid production, precise metering, and adaptability to complex scenarios." It is suitable for small and medium-sized construction sites, emergency projects, or projects that require frequent transfers.
