The PERUMIN mining convention is considered one of the most important mining events in Latin America, organised by the Institute of Mining Engineers of Peru (IIMP) since 1954. PERUMIN hosts the Mining Technology Exhibition EXTEMIN, presenting the most important national and international suppliers of mining goods and services.

The event takes place in Arequipa, Peru, from 16-20 September. You will find the Putzmeister exhibition stand in the outdoor area EXTERIOR 3, Stand No. 2089-90 / 2094-96.

The Putzmeister Underground Division will showcase its concrete spraying system 4210 SPM WETKRET DUAL DRIVE, as well as the low-profile concrete mixer MIXKRET 4. In addition, the Putzmeister Solid Pumps division will be present, which supplies high-density piston pumps for transporting tailings and backfilling paste in mining. Furthermore, the Putzmeister Powercreter Magnum will be exhibited, a wet shotcrete pump for concrete repair works.

Diesel or electrically powered concrete spraying with SPM 4210 WETKRET DUAL DRIVE

The SPM 4210 WETKRET DUAL DRIVE version has a dual drive system so that all the components can be operated both by diesel engine and electrically. The machine is optionally available with an on-board electric or diesel air compressor. Its reinforced spraying arm provides a vertical spraying reach of 10m, and the maximum concrete output of the Putzmeister double-piston pump mounted on the equipment is 20m³/h.

The proportional remote control, which can be operated both by cable and wireless, allows the easy operation of the spraying arm as well as the regulation of the concrete output and the adjustment of the pre-defined additive dosage. The peristaltic additive pump is equipped with and automatic dosing device to synchronize the additive dosage with the concrete flow, assuring spraying accuracy and quality. With heavy-duty axles and a reinforced articulated turning system, the SPM 4210 WEKTRET series is designed for the rough working conditions in mining.

Low-profile concrete mixer MIXKRET 4 with ICVD drive system

MIXKRET 4 is equipped with a six-cylinder, 130kW turbo engine, providing high climbing and moving power as well as the possibility to work at high altitudes. With the ICVD drive system (Integrated Continuously Variable Drive) it is possible to drive through the entire speed range without interrupting the traction force, increasing comfort for the driver and reducing fuel consumption. The compact design and heavy-duty axles, both used for steering and driving (4WD and 4WS), provide mobility and manoeuvrability in narrow galleries and tunnels.

Furthermore, the machine features an automatic speed control system for moving down slopes fully loaded at the maximum secure speed. The cabin, mounted in machine direction, and the night-vision camera at the rear, facilitate manoeuvring and ensure visibility conditions at all times, increasing safety. The concrete transporting and mixing drum of Putzmeister Mixkret 4 provides a concrete capacity of 4m³ and optionally includes an additive discharging system for transporting and transferring additives to the shotcrete equipment.

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 11km and achieve effective pumping throughputs of approximately 500m³/h.
