Concrete batching plants come in two basic designs. In a wet mix plant (also called a central mix or wet batch plant) all ingredients are mixed in a stationary mixer at the plant, and ready concrete is discharged into the truck. In a dry mix plant (dry batch or transit mix plant) the materials are weighed at the plant and loaded into the truck mixer, and the concrete is mixed in the drum. Vettertech builds both types: our references include an 80 m³ dry batch concrete plant in Manchester, UK, as well as wet mix plants with twin-shaft mixers.
How a wet mix plant works
Aggregates, cement, water and admixtures are weighed and discharged into a twin-shaft or planetary mixer. After a short mixing cycle, homogeneous concrete is discharged into the truck mixer, which only agitates it on the way to site.
How a dry mix plant works
Aggregates and cement are weighed and loaded, together with water, into the truck mixer through a loading chute, usually fitted with dust collection. The mixing happens in the truck drum during loading and transport.
Wet mix vs dry mix compared
| Where concrete is mixed | Wet mix: in the plant mixer. Dry mix: in the truck mixer drum. |
|---|---|
| Quality and consistency | Wet mix: very consistent, every batch is mixed the same way. Dry mix: depends on drum condition, loading and travel time. |
| Initial investment | Wet mix: higher, because of the plant mixer. Dry mix: lower. |
| Truck loading time | Wet mix: short, the concrete is ready. Dry mix: longer, mixing continues in the truck. |
| Maintenance | Wet mix: mixer wear parts such as paddles and liners. Dry mix: more wear on truck drums. |
| Typical use | Wet mix: ready-mix, high-strength and special concretes, precast. Dry mix: markets where transit mixing is customary, such as the UK and the US, and limited budgets. |
Which should you choose?
Choose a wet mix plant if consistent quality, high output and short truck loading times matter most, for example for ready-mix production and precast. A dry mix plant can make sense where transit mixing is standard practice and the initial budget is limited. Capacity and site layout matter for both; see our capacity calculation guide and concrete batching plants for sale.
