Putzmeister to showcase mining solutions at IMME 2018

Putzmeister, a worldwide leading solution provider for pumping, mixing and placing concrete, mortar and industrial solids, will be showcasing its low profile concrete mixers and concrete spraying equipment used in mines and tunnels, at the IMME 2018 in Kolkata.

Given the small section galleries and harsh conditions of underground mining, Putzmeister’s line of low profile concrete mixers Mixkret provide optimal manoeuvrability and mobility, thanks to their compact size and powerful engines. Also notable is their capacity to operate in high altitude environments.

The recently launched Mixkret 3 is the only mixer in the market of its height (2,200 mm) that has a mixing capacity of 3 cu m.

Putzmeister’s Wetkret line of machines service high volume underground mining projects the world over, ensuring safe and accurate concrete spraying. The company also offers mortar equipment for screeding and grouting work in the construction of mines and tunnels. The Wetkret 4 series, ideal for narrow galleries in mining, boasts two spraying arm versions, one with a maximum vertical reach of 10 m and the other of 7.5 m.

Advanced mining methods such as ‘Cut and Fill’ or ‘Room and Pillar’, safety considerations, environmental aspects as well as economic reasons mandate backfilling of voids created during the mining process. Putzmeister’s KOS (S transfer tube) and HSP (seat valve) pumps and ZX piping systems handle abrasive material and conveying distances up to 11 km from the mixing facility with no pumps installed en route.

With an ability to handle foreign bodies in material up to two-thirds of the pipeline’s diameter, the Putzmeister HSP pumps have proven effective in transporting tailings.

Reliable mineral slurry transportation is the heartbeat of the mineral processing system which ensures the smooth flow of the entire process. Putzmeister’s solid pumps are capable of transporting high volumes from the crushing facility to their next processing point, such as de-watering or intermediate storage. Mine de-watering and conveying sludge are also efficiently handled by these pumps.

The lifting of personnel and cargo, along with the installation of pipes and fans, is vital in underground mining operations. Putzmeister’s Minelift 4, a scissor lift platform is mobile and secure, and is available in two configurations. It provides a safe working platform for the elevation of personnel and cargo in underground works. For piping installation, it additionally includes an extendable platform, a crane with high load capacity and a pipe handling system.
