Introduction and Operating Experience of the Energy-Saving Rotor for Inward Type Headbox Screen

Abstract

It is accepted that, in the pulping process, we are able to achieve a reduction in power consumption by installing an energy-saving rotor at the screen and additionally by reducing the rotating speed of the rotor.
On this basis, we installed the same kind of rotor to the headbox screen in the paper making process in order to assess any possible energy savings. We have now carried out actual machine tests using the energy-saving rotor manufactured by Aikawa Iron Works Co., Ltd.
In this paper, I will explain our operating experience of the energy saving as a result of installing the energy-saving rotor for inward type headbox screens in the case of N-2 M/C.
