Integrated Stabilized Soil Mixing Plant

What is an Integrated Stabilized Soil Mixing Plant

The integrated stabilized soil mixing plant, also known as an all-in-one stabilized soil batching plant or water-stabilized integrated machine, is a complete set of equipment that highly integrates core functional modules required for stabilized soil mixing, including aggregate batching, powder conveying and metering, mixing, finished product storage, and intelligent control into a single or a few units for rapid transshipment.

Abandoning the decentralized layout of traditional split-type stabilized soil plants, it adopts a modular steel structure and integrated conveying design to realize “integrated before delivery, ready for production upon arrival”. Specially designed for efficient and flexible production of stabilized soil mixtures, it can mix cement-stabilized soil, lime-stabilized soil, industrial waste-stabilized soil and other mixtures to meet the construction needs of various road bases and sub-bases.

Product Selection: Split-type vs. Integrated Type

2.1 Scenarios for Choosing the Integrated Stabilized Soil Mixing Plant

• Limited site: Narrow construction site without conditions for complex foundation pouring; the integrated type requires no large-area hardened site and can be directly placed for use.
• Short construction period & frequent relocation: Suitable for short-distance municipal road construction, rural highway reconstruction and expansion, temporary projects, etc. Relocation only needs flatbed transportation, with short disassembly and assembly time (usually 1-3 days to put into production).
• Small and medium-scale batch production: Daily output of 300-600 tons with limited single project dosage; no large fixed station is needed, and the integrated type is more cost-effective.
• Lightweight construction demand: Projects sensitive to equipment investment cost and aiming to reduce installation, commissioning and relocation costs.

2.2 Scenarios for Choosing the Traditional Split-type Stabilized Soil Plant

• Super large-scale continuous construction: Mass production in long-term fixed sites such as expressways and airport runways (single unit hourly output ≥600 tons, long-term continuous operation).
• Extreme working condition adaptation: Complex projects requiring customized multiple bins, multiple powder silos, special dust removal/explosion-proof systems; the split-type allows flexible module expansion.
• Long-term fixed station: Projects with a construction period of more than 1 year and stable site; the split-type layout is more conducive to long-term operation and maintenance and capacity optimization.

Product Advantages of the Integrated Stabilized Soil Mixing Plant

1. Integrated design, small footprint & easy installation: All functional modules are integrated in a steel structure frame, with a floor area only 1/3-1/2 of the split-type (e.g., 400-type integrated machine covers about 30×12m). No complex foundation is needed; only power and water connection and commissioning are required upon arrival, shortening the installation period by 70%.
2. High efficiency & precision, stable proportion: Adopts twin-shaft compulsory mixer (mixing time 8-10s), equipped with high-precision belt scales and spiral electronic scales. Aggregate metering accuracy is ±1.5%, powder ±1%, water ±1%, ensuring uniform mixture gradation and avoiding segregation; the variable frequency speed control system can quickly adjust the proportion to adapt to different construction needs.
3. Intelligent control & easy operation: Equipped with PLC + touch screen control system, supporting one-key start/stop, automatic metering, fault self-diagnosis, data storage and traceability. Only 1-2 operators are needed for production, reducing labor costs.
4. Strong adaptability & wide material compatibility: Can handle soil, sand, fly ash with particle size ≤60mm, and powders such as cement and lime. Supports production of various mixtures like lime-soil, water-stabilized soil, graded crushed stone, adapting to all kinds of stabilized soil raw materials.
5. Environmentally friendly, durable & easy maintenance: Standard pulse dust removal system to effectively control dust emissions; key components (such as mixer blades, conveyor belts) are made of wear-resistant materials for easy replacement; modular layout allows maintenance without shutdown and disassembly, reducing operation and maintenance costs.
6. Flexible relocation & high cost performance: The whole machine adopts detachable modular design, which can be quickly transferred by flatbed truck with high reusability. Compared with split-type equipment, initial investment and later relocation costs are reduced by 40%-60%.

Working Process of the Integrated Stabilized Soil Mixing Plant

1. Pre-start preparation: Check raw material reserves in each silo, power and water connection, equipment lubrication and sealing; set the mixture proportion (aggregate, powder, water volume parameters) via the touch screen.
2. Loading and metering: Loader loads aggregates into hoppers; belt conveyor conveys aggregates to belt scales for metering according to the set proportion; powder silo accurately conveys powder to the mixer via screw conveyor and spiral electronic scale; water pump sprays water according to the proportion.
3. Forced mixing: Aggregates, powder and water enter the twin-shaft mixer synchronously. The mixing shaft reverses to drive blades to extrude, shear and convect materials, fully mixing for 8-10s to ensure uniform mixture without segregation.
4. Finished product conveying: The mixed mixture falls into the finished product inclined belt conveyor through the mixer discharge port and is conveyed to the finished product storage silo for temporary storage.
5. Loading and transshipment: After the transport vehicle arrives, the silo door is opened by cylinder control, closed after loading, and the vehicle transports the mixture to the construction site for paving and compaction.
6. Shutdown and finishing: After production, stop aggregate, powder and water supply in sequence, idle the mixer for 30s to clean residual materials; turn off the power, clean the equipment and perform maintenance.

Operating Precautions

Pre-start Precautions

1. Conduct comprehensive inspection on oil circuit, circuit, transmission belt, steel wire rope and limit devices to ensure no looseness, damage or blockage.
2. Check asphalt tank insulation heating, burner oil circuit and dust removal system; preheat asphalt to normal working temperature in advance.
3. Verify equipment grounding, emergency stop button and safety guardrail; operators must hold certificates and wear labor protection articles.
4. Input asphalt mixture formula in advance and confirm proportion parameters before starting equipment.

Operating Precautions

1. Start feeding gradually only after no-load preheating; no direct full-load start-up of cold machine.
2. Monitor discharge temperature, metering data, combustion flame and dust removal negative pressure in real time; stop immediately for inspection in case of abnormal temperature or proportion deviation.
3. Do not open maintenance doors, reach into mixing host, drum or transmission parts, or cross running equipment during operation.
4. Do not modify proportion parameters at will, over-capacity produce, or feed over-moist aggregate directly.
5. Regularly check wear of mixing blades and liners; replace severely worn parts timely to avoid unqualified mixture quality.

Shutdown and Final Precautions

1. Shutdown sequence: stop feeding → empty host mixture → stop burner → delay drum cooling → disconnect main power.
2. Clean residual aggregate on belts, dust in dust bags and residual asphalt in pipelines daily after shutdown; conduct insulation, anti-freezing and anti-rust treatment.
3. Empty all materials in asphalt pipelines, aggregate silos and storage silos before long-term shutdown or relocation; protect equipment from rust, water and dust.
4. Keep regular equipment maintenance records and replace lubricating oil and wearing parts as per Jianxin Machinery maintenance manual.
