The drum cardPublished 19/4 at 10:14
Rotary drum cutters are becoming increasingly popular with professional contractors all over the world due to their extreme versatility and high production rates. PDi’s Andrei Bushmarin presents the latest news from this fast developing sector.
A Simex TF 1100 excels on a quarry job
Specialist contractor Monte Bianco Srl, based in Stallavena di Grezzana, in the province of Verona, Italy, is using a TF 1100 drum cutter from Italian manufacturer Simex to extract calcium carbonate from one of the two quarries operated by the company. Low vibrations and smooth milling capabilities make the TF series particularly suitable for quarrying applications. The attachment ensures selective breaking of the rock mass while keeping the surrounding structures intact. The TF 1100 produces crushed material of a required particle size for subsequent grinding at the company's specialised plant. Earlier efforts involving a hydraulic hammer proved ineffective as the chisel tended to get stuck in the limestone. Given that and the sensitivity of the area, the contractor opted for a Simex drum cutter. The company was impressed by the pin point precision and high production rates delivered by the attachment. With an average production rate of 50m³/h, the cutter provided a constant flow of crushed material to the company's processing plant.
Rock.Zone updates its ‘Rockwheel’ range with new features
Germany based trendsetter in drum cutters Rock.Zone has added new models to its flagship Rockwheel series. Featuring an extended housing and paddles instead of picks, the Rockwheel soil mixers allows users to reduce costs through in-situ mixing.
When equipped with a brush, a Rockwheel drum cutter is handy for cleaning and scrubbing applications such as removing concrete from piles. Also new Rockwheels intended for demolition have massive helix shaped bars and a robust housing made from Hardox to ensure simultaneous cutting of steel rebar when demolishing reinforced concrete structures. Featuring only one rotary drum, Rockwheel ‘TC’ trench cutters have been designed for making small trenches. The stabilising wheel helps alleviate the stress on the excavator’s slewing ring. A Rockwheel cutter with two drums can also be used together with a ripper tooth.
