Home > SMP1000G Stabilized Soil Mixing Plant — 1,000 t/h, 6-Bin (Largest)
The SMP1000G is the larger of the two TRUEMAX stabilized soil mixing plants — 1,000 t/h of continuous output for the biggest road, airport and rail base-course operations. It steps up from the 800 t/h SMP800G in two ways that matter on a mega-project. First, the continuous mixing unit is driven by twin 75 kW motors instead of a single 110 kW unit, which gives 150 kW of installed mixing power, symmetrical loading on the mixing shafts and useful torque reserve at full throughput. Second, the aggregate batcher gains a sixth 15 m³ bin — six aggregate types instead of five — so the plant can carry an extra fraction in the mix design, commonly a reclaimed or recycled aggregate, a finer sand or a special gradation that the five-bin plant cannot.
That combination is what makes the SMP1000G the model TRUEMAX builds for the largest stabilized-base operations: mega-highways, airport runway and apron base, heavy-duty railway subgrade, and large municipal road programmes where the laying paver runs at the maximum sustained rate. Like the SMP800G, it is a continuous-mix plant — no batch cycle — with VFD-controlled aggregate discharge holding the gradation as production runs and a 12 m³ finished-product hopper buffering the output so dump trucks change without stopping the plant. Total installed power for the main plant is 250 kW. It is built and tested at the TRUEMAX factory in Haining to ISO 9001:2015 and CE standards, supplied with the same complete after-sales programme — three-minute response, 24-hour solutions, remote intelligent service.
1. 1,000 t/h continuous output — TRUEMAX's largest stabilized-soil throughput — 25% more than the SMP800G — fed steadily through a continuous mixing process for the highest-rate paving operations.
2. Twin 75 kW motors on the mixing unit — Two motors driving the continuous mixer instead of one give symmetrical shaft loading, torque reserve at peak throughput and a measure of redundancy on a flagship plant that runs long, continuous days on a mega-project.
3. Six aggregate bins, six aggregate types — Six 15 m³ bins handle six aggregate types — one more than the SMP800G's five — for mix designs that need an additional fraction. The sixth bin is commonly used for reclaimed asphalt pavement (RAP), recycled crushed concrete, a special fine sand or an additional stone size that the five-bin plant cannot carry.
4. VFD-controlled gradation — Each aggregate bin's discharge speed is regulated by a variable-frequency drive, so the proportion of every fraction entering the mixer is held in real time as production runs — the same continuous-mix gradation control as the SMP800G, scaled to six streams.
5. Per-component weighing accuracy — Cement and water are metered to ±1% (per each component unit), aggregate to ±2% — the same accuracy band as the SMP800G, held by the same component-level metering principles.
6. Same 12 m³ finished-product hopper — The output hopper stays at 12 m³ because what it does is buffer the truck-change-over, not match plant throughput — at 1,000 t/h the trucks simply cycle faster underneath the hopper rather than waiting longer at it.
7. Handles cement, lime and combination mixes — Cement-treated base, lime-stabilized soil and combination stabilized-soil mixes are all configurable through silo and metering — binder type is not built into the mixer.
8. 250 kW main-plant power and full TRUEMAX service — 250 kW total for the main plant (excluding silos and screws), with pre-sale tailored configuration, on-site commissioning and operator training, three-minute service response, 24-hour solutions, and a remote intelligent service and self-diagnosis system.

Like the SMP800G the plant is laid out along the material flow rather than around a central mixer, but with one additional aggregate bin in the row, larger drive equipment at the mixing unit, and the foundation and electrical supply sized to a 250 kW main plant. The 12 m³ finished-product hopper still sits over the truck-loading lane at the discharge end; at 1,000 t/h the dump-truck access plan is the part of the layout most worth getting right. Read the general arrangement against the foundation drawing, silo layout and truck routing to confirm the plant fits the site.
Multi-lane highway and expressway works with long sustained sections of cement-treated base draw exactly the kind of throughput the SMP1000G is built for, the sixth bin available for an extra gradation or recycled fraction the project specifies.
Airport pavement programmes need enormous, continuous base-course supply — runway, taxiway and apron base layers together. A 1,000 t/h plant matches the rate at which an airport laying operation can advance.
High-speed and heavy-freight railway subgrades use stabilized soil layers under the ballast or slab. The SMP1000G supplies these continuously and at scale across the long, linear nature of rail projects.
Government road programmes — provincial highways, ring roads, road rehabilitation — often run multiple sections concurrently from one base-course plant; the SMP1000G's throughput and six aggregate bins suit the variety of mix designs such programmes call for.
Three real differences. The SMP1000G produces 1,000 t/h versus 800 t/h on the SMP800G — 25% more. The mixing unit is driven by twin 75 kW motors rather than a single 110 kW one, with the symmetrical loading and redundancy a flagship plant benefits from. And the aggregate batcher has six bins instead of five, so an extra aggregate fraction can be carried in the mix. Pick the SMP1000G when the project's daily volume sustains 1,000 t/h, or when the mix design genuinely needs that sixth bin; pick the SMP800G otherwise.
Two reasons. First, symmetrical loading — twin motors apply mixing torque from both ends of the chamber rather than driving from one side only, which spreads stress on the mixing shafts and bearings on a flagship plant that runs long days. Second, useful redundancy at high throughput: at 1,000 t/h the cost of an unscheduled stop is high, and a twin-motor drive simply behaves better at sustained peak load than a single, larger motor.
Whatever the mix design needs that five bins cannot hold. Common uses are: a reclaimed asphalt pavement (RAP) fraction for sustainable road bases, a recycled crushed-concrete fraction for the same reason, an additional fine sand or filler for tighter gradation control, or a special aggregate size required by a particular specification. On projects where the mix design is simpler, the sixth bin can simply increase reserve capacity.
Because the hopper's job is to buffer the truck change-over, not to scale with plant output. It holds enough material to keep the plant running through the few seconds it takes for one dump truck to pull out and the next to pull in. At 1,000 t/h that means trucks cycle through faster underneath the hopper, not that the hopper holds more material — sizing it larger would not improve continuity.
Yes. Both are continuous-mixing plants — material flows through the plant constantly rather than being mixed in discrete batches, with VFD aggregate control holding gradation and per-component metering holding binder content. The SMP1000G scales that principle to a sixth bin and a twin-motor mixer; the working principle is unchanged.
No. It is a stabilized soil mixing plant — a different category from a concrete batching plant. The SMP1000G produces stabilized base material (aggregate with a low binder content, around 3–6% cement or lime by weight) for road and airport pavement layers, not ready-mix concrete. If you need ready-mix concrete, look at the TRUEMAX CBP (Concrete Batching Plant) range instead.
Total power for the main plant is 250 kW, excluding cement silos and screw conveyors which are configured to your project. With silos, multiple screws, lighting, the control room and ancillaries, the full plant electrical load is higher — confirm the site's medium-voltage supply and transformer sizing during planning. Foundation, dump-truck access and aggregate stockpile area also scale with the larger throughput.
Standard supply is the main plant: the 6-bin aggregate batcher with belt, the twin-motor continuous mixing unit, the 12 m³ finished-product hopper, and the weighing and control system. Cement or lime silos, screw conveyors, foundation design, installation, commissioning and operator training are configured and quoted to your project. After-sales runs to a three-minute response, 24-hour solutions and a remote intelligent service with self-diagnosis.
The SMP1000G is the flagship of the TRUEMAX stabilized-soil family, paired with the smaller SMP800G at 800 t/h and 5 bins. Together they are the only two TRUEMAX plants for stabilized base — entirely separate from the concrete batching plant family (CBP60S to CBP240S stationary, CBP60M to CBP100M mobile, CBP180C to CBP240C modular), which produces ready-mix concrete rather than stabilized base. The SMP1000G is the model to specify when the project demands both maximum throughput and the wider mix flexibility a sixth aggregate bin gives.
On a mega-project the SMP1000G sits behind a paving train running at high sustained rate. Aggregate comes in from stockpiles, the six bins hold a full mix design (often including a recycled or reclaimed fraction), the continuous mixer combines it with cement or lime and water, and the 12 m³ output hopper feeds dump trucks that shuttle the stabilized material to the paver. Continuity is what matters at this scale — a one-hour stop at the plant is a one-hour stop in the road being built — and continuous-mix plants with twin-motor mixers are how that continuity is engineered.
The decision between the SMP800G and the SMP1000G often turns on the sixth bin as much as on the throughput. Projects increasingly specify recycled aggregate or reclaimed asphalt pavement in road-base mixes for sustainability, which needs its own bin and discharge control. Highway specifications with tight gradation bands may need an additional sand or filler fraction. On projects where the mix design is simple and the paver does not need 1,000 t/h, the SMP800G is the better-matched plant; on projects where either the volume or the materials call for more, the SMP1000G is the model built for it.
