Putzmeister Underground Division: concrete spraying technology

Putzmeister has designed and manufactured concrete spraying equipment for more than 30 years. The expertise acquired over these years, together with ongoing investment in research and development, has made us a leading company in this field of application.

With output rates of up to 30m³/h and spraying reaches of up to 17m, our concrete spraying systems guarantee high performance and reliability in mines and tunnels all over the world. Together with Sika, the Swiss chemicals company, Putzmeister forms a global strategic alliance for the development of sprayed concrete technology, improving application processes and efficiency.

SPM 4210 WETKRET and MIXKRET 4 - the perfect combination for concrete spraying in mining

SPM 4210 WEKTRET is Putzmeister's latest series of shotcrete equipment, providing a vertical spraying reach of 10m.

A proportional remote control allows the easy control of the spraying arm movements. With state-of-the-art axles and a reinforced turning system, the chassis is ideal for the rough working conditions in mining.

The series includes a dual-operated version (diesel and electric) as well as a rotor pump version which is suitable for both wet and dry spraying processes. The new low-profile concrete mixer, Putzmeister MIXKRET 4, has been designed to complement and enhance the shotcreting process in mining.

Putzmeister solid pumps - solutions for transporting and storing sludge and high-density materials

The solids pumps company of the Putzmeister Group manufactures high density piston pumps for pumping slurries, sludges and pastes.

In mining, our pumps transport the tailings to the dam/filter or transport backfilling paste into the underground mines. The pump system features a piston pump, a hydraulic power pack to drive the pump and an electric cabinet with a PLC, control and operation panel.

Putzmeister piston pumps can operate with a solid content of up to 85 %, depending on material composition. With an output of up to 150bar they can pump over distances of up to 11 km and achieve effective pumping throughputs of approximately 500 m³/h.

Putzmeister solid pumps technology - safe, economic and environmentally friendly

The core components of our delivery program are S-transfer tube piston pumps (KOS), seat valve piston pumps (HSP), ball valve piston pumps (KOV) and ZX piping systems.

Special advantages of the Putzmeister pumping system:

• With paste transport less cement is needed for underground disposal than for slurry transport
• On the surface, the lower water content means rapid self-compaction which prevents uncontrolled runoff
• Environment protection by saving water
