Screw conveyors for fresh concrete

Ensure uniform and continuous transport of fresh concrete from mixers to molds, minimizing segregation and maintaining mix integrity in precast concrete applications.

Conveys and Mixes Fresh Concrete

The CMC Screw Conveyors from WAMGROUP are designed to enhance the efficiency of precast concrete production by reliably conveying fresh concrete to molds without the risk of segregation. Unlike belt conveyors, the CMC utilizes an adjustable helicoid screw flighting system, ensuring even mixing and continual discharge. This equipment is ideal for applications producing concrete panels, blocks, pipes, and slabs in both building and construction industries.

Equipped with wear-resistant rubber drop-bottom troughs, CMC Screw Conveyors handle bulk solids with minimal blockage risk, effectively managing large aggregate particles. The adjustable mixing paddles allow for precise control of concrete throughput, optimizing the energy efficiency of the process.

The CMC model operates seamlessly under continuous or manual processes, boasts a compact footprint, and features a direct or offset gear motor suited to your specific needs. Its robust construction from carbon steel and optional powder coating extend its durability, making it a cost-effective solution with low maintenance demands. When required, the conveyor’s design allows for quick cleaning and easy replacement of parts, ensuring minimum downtime in high-demand production environments.
