CSS-1 Single Shaft Concrete Mixer a

CONSTMACH's CSS-1 single shaft concrete mixer represents a practical solution for facilities focused on reliable, continuous concrete production. With a 1,500-liter charging volume that yields 1,000 liters of compacted concrete, this mixer handles standard concrete batches efficiently while maintaining consistent output quality. The design prioritizes durability and ease of maintenance, two factors that directly impact operational costs in concrete production environments.

The mixing mechanism centers on a robust pulley-chain drive system that transfers power from a 37 kW electric motor and heavy-duty gearbox to the main shaft. This configuration delivers sufficient torque for thorough material blending without creating excessive mechanical stress on components. The mixing arms feature 25 mm Ni-Hard wearing plates, which provide superior abrasion resistance compared to standard steel. These plates maintain their geometry longer under the constant friction of aggregate movement, reducing the frequency of replacement cycles. Similarly, the main body incorporates 15 mm Ni-Hard plates while side body sections use 15 mm Hardox 450, creating a layered defense against wear in different mixer zones.

What sets the CSS-1 apart is its attention to maintenance accessibility. Replaceable liners throughout the mixing chamber mean worn sections can be swapped out without dismantling major assemblies. This modular approach cuts downtime significantly when maintenance becomes necessary. The automatic lubrication system continuously services shaft bearings during operation, eliminating the risk of bearing failure from inadequate manual greasing. SKF and FAG brand heavy-duty bearings support the shaft, chosen specifically for their load capacity and longevity in industrial mixing applications.

The hydraulic discharge door operates smoothly under the weight of concrete loads, and its hydraulic mechanism requires less manual effort than mechanical alternatives. An access hatch allows inspection of internal components without full disassembly, while a maintenance door safety switch prevents accidental operation during servicing. The emergency stop button provides immediate shutdown capability, a critical safety feature when working around rotating machinery.

This mixer excels in general-purpose concrete production where consistency matters more than specialty mix capabilities. Plants producing standard structural concrete, ready-mix operations handling conventional orders, and precast facilities running routine production schedules will find the CSS-1 matches their operational rhythm. The 1,250-liter fresh concrete output per batch suits medium-volume operations that need reliable throughput without the complexity of larger twin-shaft systems.

CONSTMACH engineers the CSS-1 for straightforward operation and predictable performance. The mechanical simplicity reduces the variables that can cause production interruptions, while the quality of wearing components extends service intervals. For concrete producers who value uptime and manageable maintenance schedules, this single shaft mixer delivers exactly what commercial concrete production demands: steady output backed by durable construction.
