CTS-2 Twin Shaft Concrete Mixer

CONSTMACH's CTS-2 twin shaft concrete mixer represents a significant advancement in industrial mixing technology, specifically engineered for applications demanding consistent, high-quality concrete production. This 2 cubic meter capacity mixer combines powerful performance with practical design considerations that matter in real-world production environments.

The CTS-2 operates on a dual-motor configuration, with each 37 kW motor driving independent mixing shafts. This twin-shaft arrangement creates a compulsory mixing action where spiral blades throw material from opposite sides of the mixing chamber toward the center. The result is a thorough integration of all components, from coarse aggregates to fine particles, ensuring uniform distribution throughout the batch. The charging volume of 3,000 liters accommodates raw materials efficiently, producing 2,500 liters of fresh concrete or 2,000 liters when compacted. These capacities make the unit particularly well-suited for medium-scale operations in precast production facilities, block manufacturing plants, and paver production lines.

Durability plays a central role in the CTS-2's design philosophy. The mixer incorporates strategically placed wear-resistant materials where they matter most. Side body plates use 15 mm Hardox steel, offering excellent resistance to abrasive aggregates during the mixing cycle. The main body features 20 mm Ni-Hard plates, while the mixing arms themselves are protected by 30 mm Ni-Hard plates. This graduated approach to wear protection balances longevity with cost-effectiveness, placing the most robust materials in high-impact zones.

Water injection occurs through pressurized jets that force moisture deep into the aggregate mass rather than simply pouring it over the surface. This method accelerates the hydration process and ensures cement particles coat every aggregate surface uniformly. The rapid absorption of water throughout the mix contributes to shorter cycle times without compromising concrete quality. When cement slurry reaches all aggregate particles evenly, the resulting concrete achieves optimal strength characteristics.

Operational convenience extends beyond mixing performance. An automatic lubrication system maintains bearing surfaces and moving components without manual intervention, reducing maintenance downtime and extending component life. The hydraulic discharge door operates smoothly under the weight of heavy concrete batches, and a maintenance door safety switch prevents accidental operation during service intervals. These features reflect practical experience in concrete production environments where reliability directly impacts productivity.

The compact footprint of the CTS-2 suits facilities where space comes at a premium, yet its output capabilities support demanding production schedules. Fast mixing cycles mean more batches per hour, translating to higher daily volumes without extending working hours. Whether producing concrete for dam construction, manufacturing precast elements, or supplying ready-mix operations, the CTS-2 delivers consistent results batch after batch. Its design acknowledges that concrete mixing success depends on combining speed with completeness, and CONSTMACH has calibrated this balance carefully in the CTS-2 model.
