SMP800G Stabilized Soil Mixing Plant — 800 t/h Continuous Mixing

The SMP800G is a heavy-duty stabilized soil mixing plant engineered for continuous production of road-base materials at 800 t/h. Unlike batch-type concrete batching plants, it operates on a continuous flow process: aggregates are discharged from five 15 m³ bins via VFD-controlled gates, blended with metered streams of cement or lime and water, and processed through a 110 kW continuous mixing unit. The stabilized material discharges into a 12 m³ finished-product surge hopper, ensuring uninterrupted truck loading and continuous paving operations. Designed specifically for low-binder applications (3%–6% cement or lime by weight), the system guarantees strict component-level metering accuracy (±1% for cement and water, ±2% for aggregates). Manufactured to ISO 9001:2015 and CE standards, the SMP800G integrates premium electrical and mechanical components for reliable high-throughput infrastructure construction.

1. 800 t/h Continuous Output — Delivers high-volume continuous flow measured in tonnes per hour, eliminating batch-cycle interruptions.

2. VFD Aggregate Discharge — Variable-frequency drives dynamically regulate discharge speeds across all aggregate bins for real-time gradation control.

3. 5-Bin Aggregate System — Incorporates five 15 m³ bins supporting complex multi-fraction mix designs for modern base-course specifications.

4. 110 kW Continuous Mixing Unit — Optimized for high-throughput through-flow mixing of stabilized soils, replacing traditional twin-shaft concrete mixers.

5. Component-Level Precision — Maintains strict metering tolerances (±1% binder/water, ±2% aggregate) essential for low-binder structural integrity.

6. 12 m³ Surge Hopper — Provides intermediate buffering above the truck-loading lane to allow seamless vehicle interchange without plant stoppage.

7. Multi-Binder Versatility — Compatible with cement-treated, lime-stabilized, and combination soil formulations via adjustable silo and metering setups.

8. 177 kW Main Plant Power — Balanced power consumption (excluding silos and screw conveyors) engineered for heavy-duty industrial deployment.

Dimensions & Working Range

The SMP800G layout is arranged along a linear material flow rather than a centralized tower. Five aggregate bins in sequence discharge onto a collector belt, where cement or lime is introduced via metered screw conveyors. The combined stream enters the continuous mixing unit before discharging into the 12 m³ surge hopper positioned directly above the truck lane. Installation planning must evaluate the linear footprint against site topography, aggregate stockpiling areas, and dump-truck transit routes.

Applications

The SMP800G is engineered for high-capacity continuous stabilization, delivering 800 t/h of homogeneous road-base material for major infrastructure projects.

Cement-Treated Base (CTB) for Highways

Highways & Expressways: Produces cement-treated base (CTB) layers at high output rates to support continuous paving operations.

Lime-Stabilized Subgrade Construction

Subgrade Stabilization: Integrates lime-stabilized soil preparation for weak subgrades, enhancing bearing capacity and reducing plasticity.

Airport Runway & Apron Subbase

Airport Infrastructure: Delivers precise, high-volume base and subbase materials for heavy-duty runways, taxiways, and aprons.

Railway Subgrade & Freight Terminals

Railroad Engineering: Supplies continuous stabilized subgrade layers for high-load freight and passenger rail corridors.

FAQs

How does a stabilized soil mixing plant differ from a concrete batching plant?

A concrete batching plant produces ready-mix concrete in discrete batches utilizing a twin-shaft compulsory mixer and high binder content (12%–15%). The SMP800G produces stabilized base materials with low binder content (3%–6% cement or lime) via continuous mass-flow mixing for road construction.

What are the primary applications for the SMP800G?

Primary applications include cement-treated base (CTB) for highways, lime-stabilized subgrade preparation, airport runway base construction, and heavy-duty railway subgrade stabilization.

What does 'continuous mixing' mean regarding operational cycles?

Continuous mixing means materials flow through the plant without batch-by-batch interruption. Aggregate, binder, and water are metered simultaneously, allowing the plant to run continuously without stopping between batches, matching paving train speeds.

Why is productivity measured in tonnes per hour instead of cubic meters?

Stabilized soil output is quantified by mass because binder proportions (3%–6% by weight) rely on dry aggregate mass ratios, and transport vehicles are weighed by load tonnage. Tonnes per hour (t/h) is the standardized industry metric.

How is aggregate gradation regulated in a continuous system?

Gradation is regulated via VFD (variable-frequency drive) motors on each aggregate bin discharge gate, allowing real-time speed adjustments to maintain strict mix proportions on the collector belt.

What is the operational function of the 12 m³ surge hopper?

The 12 m³ surge hopper acts as an interim buffer above the truck lane. It holds mixed material briefly during dump-truck interchanges, preventing plant shutdowns and ensuring continuous feed to downstream operations.

Can the plant process both cement and lime stabilization?

Yes. The plant accommodates cement, lime, or combined binder programs through simple reconfiguration of the storage silos and metering screw assemblies.

What components are included in the standard plant configuration?

Standard supply comprises the main continuous plant: 5-bin aggregate batcher, collector belt, 110 kW continuous mixing unit, 12 m³ surge hopper, weighing electronics, and control cabin. Auxiliary equipment like binder silos and screw conveyors are quoted per project requirements.

Positioning within the TRUEMAX Range

The SMP800G is part of the TRUEMAX stabilized soil plant series, operating alongside the larger SMP1000G (1,000 t/h with six bins). While distinct from the TRUEMAX concrete batching plant family, the SMP series shares the same commitment to industrial durability, precise ECU weighing, and rigorous CE manufacturing standards. Selection within the series is determined by required hourly tonnage and mix gradation complexity.

Operational Synergy in Paving

Synchronizing the SMP800G's 800 t/h continuous output with laying pavers is critical for road construction quality. Plant interruptions directly translate to paving halts, risking cold joints and uneven compaction. The combination of VFD continuous metering and the 12 m³ surge hopper provides the operational buffer necessary to sustain steady, high-rate paving trains on major highway projects.
