Pulpers
Energy efficient solutions for paper dissolving Grubbens pulper range offers a high pulping quality, short pulping time, as well as a very low power usage.
Our solution
The Grubbens product line offers solutions for under-the-machine, bale and broke pulpers, and for high consistencies. Paper mills around the world often operate pulpers of old design which consume significant amounts of energy. Cellwood specializes in rebuilding existing pulpers – a modernization that dramatically can decrease the energy consumption, and also lead to a much higher throughput.
We offer a big variety of rotor units, where each type is designed to give optimal results for a specific paper material: virgin pulp bales, paper machine broke, guillotine broke and wet strength material. With over 2500 installations the efficiency and low power consumption is well proven.
- Some of the savings and improvements are:
- Lower energy demand – in many cases as much as 50%.
- Increased capacity by operating at higher consistencies.
- Short pulping times thanks to an optimized flow pattern with increased fiber-to-fiber friction.
- Flexible layouts, with customized pulper dimensions, for optimal use of energy
