Leading underground mining shotcrete specialist Putzmeister is adding new products to its range of underground construction equipment at this year’s world-leading construction machinery fair bauma in Germany.
The company is extending its portfolio with the launch of the new top-of-the-range mechanized shotcrete spraying machine for small sections, WETKRET 3; and a compact shotcrete batching plant, BATCHKRET 20, specially designed for underground mines.
WETKRET 3: CONCRETE SPRAYING UNIT FOR SMALL TUNNEL SECTIONS
WETKRET 3 is ideal for smaller tunnel sections. Perfect for the rugged, uneven terrain of the mine, the equipment is mounted on a compact rubber-coated crawler chassis to facilitate maneuvering even in jagged worksites.
It features a telescopic spraying arm with a vertical reach of 9 m and a horizontal reach of 7 m, which can be deployed in a minimum section of 2.5 m. It can run both on diesel and on electricity, boosting onsite mobility away from the mains.
The unit has hydraulically-operated support legs with an optional tilting system of +/-30 º that add to its stability and safety profile onsite. For upward slopes, there is an optional rear stabilizer blade; and an optional electronically-operated 50 m winch cable with 6.803 kg tractive force for downward slopes.
The engine, support legs, tilting system and the blade stabilizer can also be operated in electric or diesel mode. A proportional remote control can be used either by cable or wirelessly via Bluetooth to operate the crawler carrier, support legs, spraying arm and head as well as the optional elements.
WETKRET 3 has couplings for concrete piping on both sides for greater flexibility, while the additive and air lines run internally so no external hoses are required. The machine works well with Putzmeister's stationary concrete pump SPM 715 SYNCHRO, which combines large-scale pumping technology with compact design and easy operation.

BATCHKRET 20: COMPACT BATCHING PLANT FOR UNDERGROUND MINING
BATCHKRET 20 is a compact batching plant which completes Putzmeister Underground’s shotcrete offering for a fully-integrated, streamlined shotcrete application process.
Designed for the challenging operating environment of the mine, the new BATCHKRET 20 allows clients to bypass costlier shotcrete transporting systems, by taking the production of concrete to the heart of their operations underground and optimizing logistics.
Batching plants are processing units where these ingredients are weighed and mixed in a way that will deliver a homogeneous, consistent shotcrete formula that meets stringent quality requirements. BATCHKRET 20 has a compact footprint with an elevated production capacity of up to 20 m³/h.
The central mixing set has a cylindrical pan with 750 liter capacity, and a vertical axle with rotating blades and scrapers.
The plant also features aggregate storage hoppers with belt feeders, a 14 meter-long cement conveyor belt and a batching booth that houses the control equipment and protects it from the harsh working conditions of the underground mine.
It can be configured with three different feeding systems, including a big bag, silo or bag cutter to match the project’s requirements. Optional equipment includes a hydroprobe sensor for sands.
Technical Details: BATCHKRET 20
Length (wo feeder) / Width / Height 16.449 mm/ 10.359 mm /2.560 mm
Hopper 4/2 Aggregate Hoppers
Mixing Set Vertical Axle, 750 l Capacity
Concrete Conveyor Belt 14.000 mm
Batching Booth Station Control Panels
Configurations
Feeding System Silo (23.500 kg)
Big Bag Hopper (1.500 kg)
Bag-Cutting Hoper (250 kg)
Optional Equipment
Dosing System for 2 Admixtures
Hydroprobe Moisture Sensor for Sands
