The CTS-5 Twin Shaft Mixer is the largest model in the CTS range, and choosing it means confirming that a 5 m³ compacted batch and twin 90 kW drives are matched to a plant built for the highest production volumes and the most demanding mixes. The notes below address what buyers weigh beyond the specification table.
Where It Is Used
- Major central ready-mix plants supplying flagship building and infrastructure projects
- Roller-compacted concrete (RCC) plants for dams, large airfields and heavy pavements
- Highest-volume precast factories casting bridge girders, large segments and heavy panels
- Large dam, port, airport and energy projects requiring sustained maximum output
- Operations that need the largest batch the CTS range offers
What It Produces
Each cycle delivers 5,000 lt (5 m³) of compacted concrete from a 7,500 lt charge. The mixer handles structural and high-strength ready-mix, dense aggregate-rich RCC and large stiff precast batches, and its powerful counter-rotating action mixes very low-water and harsh mixes thoroughly while still distributing admixtures, pigment and fibre evenly. A 5 m³ batch can fill a transit mixer in a single discharge and keep multiple high-rate precast lines supplied at once.
Installation and Power
The two 90 kW motors give 180 kW of mixer drive, so the plant's electrical infrastructure, cabling, transformer and any standby generation must be engineered for this load alongside the rest of the plant. The mixer needs a hydraulic supply for the discharge door and an electrical feed for the automatic lubrication pump. Its mass and the forces it generates demand a heavy, properly engineered and founded plant structure; this is fixed central-plant equipment.
Maintenance and Wear Parts
- Side body wearing plates: 25 mm
- Main body wearing plates: 30 mm, the thickest specified across the CTS range, for the heaviest abrasive duty
- Mixing arm wearing plates: 30 mm, the primary high-wear items, inspected frequently
- Four heavily loaded shaft bearings and seals served by the automatic lubrication system; keep the reservoir filled and confirm delivery to every point
- Monitor arm and paddle clearance and adjust as wear opens it, since clearance growth slows mixing and raises power draw on a high-power machine
- RCC and aggregate-rich mixes are highly abrasive; maintain a tight liner inspection schedule and hold spare liner sets to minimise downtime
Comparison Versus the CTS-4 and Smaller Models
Against the CTS-4, the CTS-5 adds a further cubic metre of batch (5 m³ versus 4 m³), raises drive power to two 90 kW motors (180 kW versus 150 kW), and steps the main-body liner up to 30 mm for the most demanding RCC and dam-scale duty. The smaller CTS-1 through CTS-4 cover compact, mid-range, high-output and central-mix plants respectively; the CTS-5 is the choice only where the project genuinely requires the maximum sustainable output and batch size the range offers. For plants whose volumes sit below that ceiling, the CTS-4 usually gives a better balance of output, power demand and cost.
