Voith Develops Energy Efficient Rotor for Pulping Recovered Paper

Voith, Germany, has developed a new rotor, the IntensaRotor R, for pulpers used to process recovered paper. It has been operating successfully for months with industrial customers and has proven that its energy consumption is as much as 20% below the usual values. The IntensaRotor R is suitable for installation in existing Voith pulpers as well as in pulpers from other manufacturers.

During operation at both a Turkish paper mill, and at a paper producer in China, the IntensaRotor R proved that it has lower specific energy consumption at a higher throughput than its predecessors. In the first case, the daily output was increased from 260 metric tons to 300 metric tons, with an energy saving of 8% per metric ton. In the second industrial example, the amount of stock after installation of the IntensaRotor R was increased from 510 metric tons to 630 metric tons per day, while energy consumption per metric ton dropped by 12%.

 

Both the better energy balance and the higher output are due to the new rotor design. The IntensaRotor R is especially suitable for pulpers of secondary fiber applications in the low-consistency area and is delivered in various sizes.
