Voith, Germany, has brought a new IPV Rotor for virgin pulp onto the market. The new component has already proved itself for some months under mill conditions, the company says, and shows its strengths—energy consumption of the new rotor can be up to 30% less than that of conventional technologies. This also enables energy costs to be lowered by up to EUR 30,000 annually. 

 

The IPV Rotor is part of the Voith LowEnergy rotor family and was developed for application in the IntensaPulper (IP) by Voith as well as a retrofit component for existing Voith pulper and third party systems for processing virgin pulp. But the rotor can also be used to slush other clean raw materials such as broke or fresh fiber. 

The substantial reduction in energy consumption of up to 30% is achieved by an innovative design that improves flow characteristics inside of the pulper. In addition, the pulping process can be further improved through integration of a so-called bale breaker. The bale breaker loosens the hard-pressed pulp bales before actual dissolution in the pulper, and thus disburdens the rotor, which has a further positive effect on energy consumption.
