CSS-2 Single Shaft Concrete Mixer

The CSS-2 single shaft concrete mixer represents CONSTMACH's commitment to delivering reliable mixing solutions for general concrete production. With a 2,000-liter compacted concrete capacity, this mixer handles demanding production schedules while maintaining consistent output quality. The design philosophy centers on durability and ease of maintenance, two factors that directly impact operational costs and production continuity.

What sets the CSS-2 apart is its robust pulley-chain transmission system. Heavy-duty electric motors paired with industrial-grade gearboxes transfer power to the main mixing shaft through this mechanism, ensuring smooth torque delivery even under full load. The 37 kW motor configuration provides ample power for mixing various concrete types, from standard ready-mix to specialized formulations. CONSTMACH equipped the 2-cubic-meter models with dual motors, a feature that proves invaluable during unexpected equipment issues. If one motor experiences problems, production can continue with the second unit, minimizing costly downtime and keeping project timelines intact.

The mixing elements use Ni-Hard material, chosen specifically for its exceptional wear resistance in abrasive concrete environments. These components maintain their mixing efficiency throughout extended service periods, unlike softer materials that quickly degrade and compromise concrete homogeneity. The main body features 20mm Ni-Hard wearing plates, while mixing arms carry 30mm thick plates for maximum longevity in high-impact zones. Side body plates utilize 15mm Hardox 450 steel, balancing protection with structural considerations. When wear eventually occurs, the replaceable liner system allows maintenance teams to swap out components without extensive downtime or specialized equipment.

An automatic lubrication system continuously services the shaft bearings during operation. This eliminates manual lubrication intervals and ensures proper bearing care under the demanding conditions typical of concrete production facilities. CONSTMACH uses SKF and FAG heavy-duty bearings throughout the mixer, components recognized industry-wide for reliability in harsh operating environments. The hydraulic discharge door operates smoothly cycle after cycle, handling the weight and abrasiveness of fresh concrete without binding or requiring excessive maintenance.

Safety features include an emergency stop button positioned for quick access and a maintenance door equipped with a safety switch. The access hatch allows inspections and routine maintenance without complicated disassembly procedures. With a 3,000-liter charging volume and 2,500-liter fresh concrete output, the CSS-2 fits mid-range production requirements where consistent batching accuracy matters. The mixer processes material efficiently, achieving thorough blending without excessive mixing times that could affect concrete properties or reduce hourly output.

CONSTMACH's single shaft concrete mixer line, including the CSS-2, serves concrete producers who need dependable equipment that won't demand constant attention. The combination of wear-resistant materials, dual motor redundancy, and straightforward maintenance access makes this mixer suitable for operations where equipment reliability directly affects profitability. Whether handling standard structural concrete or specialized mixes, the CSS-2 delivers the performance consistency that keeps production facilities running smoothly day after day.
