CSS-0.5 Single Shaft Concrete Mixer

The CSS-0.5 single shaft concrete mixer represents CONSTMACH's dedication to delivering practical solutions for concrete production facilities. With a 500-liter compacted concrete capacity, this mixer is engineered to handle general concrete production tasks efficiently while maintaining consistent output quality. The unit's design focuses on durability and operational reliability, making it a dependable choice for facilities that prioritize steady performance without unnecessary complications.

At the core of the CSS-0.5 is an 18.5 kW electric motor paired with a heavy-duty gearbox that drives a robust pulley-chain mechanism. This power transmission system ensures smooth operation and delivers the torque necessary for thorough mixing. The main shaft is equipped with SKF or FAG brand heavy-duty bearings, known for their longevity in demanding industrial environments. One standout feature is the automatic lubrication system, which continuously maintains bearing performance during regular operation. This eliminates the need for manual lubrication intervals and reduces the risk of premature bearing failure due to insufficient lubrication.

The mixing chamber utilizes Ni-Hard material for critical wear components. The main body features 15 mm thick Ni-Hard wearing plates, while the mixing arms are protected with 25 mm Ni-Hard plates. These hardened surfaces resist the abrasive action of aggregates and cement, extending service life significantly. Side body protection comes from 10 mm Hardox 450 steel plates, offering excellent wear resistance at contact points. When these components eventually require replacement, the process is straightforward thanks to the modular liner design. This approach minimizes downtime and keeps maintenance costs predictable over the mixer's operational life.

The CSS-0.5 processes a charging volume of 750 liters, producing 625 liters of fresh concrete per batch, which compacts to 500 liters. This capacity strikes a balance between productivity and flexibility, suitable for projects ranging from ready-mix operations to precast element production. The mixer's discharge system incorporates a hydraulic door mechanism that provides reliable opening and closing cycles. Hydraulic actuation ensures consistent discharge performance and reduces the physical effort required during operation.

Safety considerations are integrated throughout the design. An emergency stop button allows operators to halt the mixer immediately if needed. The maintenance door includes a safety switch that prevents accidental operation during servicing, protecting personnel who need access to internal components. A dedicated access hatch simplifies inspection procedures and allows technicians to assess wear patterns or address maintenance requirements without extensive disassembly.

CONSTMACH's single shaft concrete mixer series is built around a philosophy of practical engineering rather than over-complication. The CSS-0.5 exemplifies this approach by combining proven mechanical components with wear-resistant materials. The result is a mixer that performs reliably day after day without demanding constant attention from maintenance teams. For concrete producers who need dependable equipment that can be serviced efficiently, the CSS-0.5 offers a well-considered package of features backed by industrial-grade components.
