Stationary Mechanical / Soil-Stabilization Plant (Plant-Mix)

General Machinery's stationary mechanical plant is a permanently installed, high-tonnage soil-stabilization plant. With 200-750 tph capacity, 3-5 cold aggregate silos, mass cement dosing and a 2×37 kW twin-shaft mixer, it produces stabilized granular road base (plant-mix) — not ready-mix concrete — for the base and sub-base layers of highways and roads. A stationary soil-stabilization plant (mechanical plant / plant-mix plant) is a permanently installed, high-tonnage plant that blends aggregate to a defined gradation with water and cement/binder and mechanically stabilizes it for the base and sub-base layers of highways and roads. Critical distinction: this plant does NOT produce ready-mix concrete; it produces stabilized granular road base (plant-mix / cement-bound granular mixture, CBGM). Unlike a concrete batching plant, the output is not discharged into a truck mixer — it is road base that is hauled to site, spread and roller-compacted. How it works Material flow is continuous and high-tonnage: Built on a permanent foundation, the plant offers higher capacity and continuity than the mobile version. Stationary vs mobile Stationary plant (200-750 tph): higher tonnage, a permanent production base, ideal for large and long projects. Mobile plant (200-600 tph): transportable, follows the advancing road works. For continuous high-tonnage regional infrastructure, the stationary plant is preferred. Applications Large highway and road projects, continuous high-tonnage road-base production, regional infrastructure bases and airport runway sub-structure. The product is always road base, never ready-mix concrete. Single-supplier complete solution General Machinery supplies the crushing-screening line that produces the road aggregate and the stationary plant-mix plant that turns that aggregate into road base from a single supplier. This gives the road contractor one point of contact from quarry to site, with matched equipment and a compatible spare-parts chain. S: Is a stationary mechanical plant a concrete batching plant? C: No. A stationary mechanical plant does not produce ready-mix concrete; it produces cement-stabilized road base (plant-mix / cement-bound granular mixture) for highways and roads. The product is road base spread and compacted on site, not concrete discharged into a truck mixer. S: What is the capacity of the stationary plant? C: The stationary soil-stabilization plant runs at 200-750 tph with a total installed power of 79-155 kW. S: How does it differ from the mobile model? C: The stationary model offers higher tonnage (up to 750 tph), a permanent foundation, a larger mixer (2×37 kW twin-shaft) and 100 m³ of aggregate storage; it is a production base for large, long-duration projects. S: How is cement dosed and how is the mix made? C: Cement/binder is added by mass dosing, water is sprayed in, and the 2×37 kW twin-shaft mixer homogenizes the material. The automation system controls dosing and gradation. S: Can I source the road aggregate from the same supplier? C: Yes. General Machinery supplies the crushing-screening line and the stationary plant-mix plant from a single supplier, giving one point of contact from quarry to road base, with matched equipment and a compatible spare-parts chain.
