Title: Inge J Johansson: Innovator in Grinding Technology

Introduction

Inge J Johansson is a notable inventor based in Täby, Sweden. She has made significant contributions to the field of grinding technology, holding a total of 3 patents. Her innovative approaches have advanced the efficiency and effectiveness of grinding processes, particularly in the treatment of lignocellulosic materials.

Latest Patents

Johansson's latest patents include a groundbreaking device in grinding apparatus. This invention involves a grinding apparatus designed to grind lignocellulose-containing materials, such as wood chips, within a precisely defined grinding space. The apparatus features cooperating disc segments that are carried by a rotating disc and a stationary disc, maintaining close spacing tolerance. To counteract the centrifugal forces acting on the rotating disc segments, the design incorporates an annular bulge at the rear of the rotating disc. This bulge contains an annular channel for mercury, which generates a counter centrifugal force, ensuring the grinding segments remain in close tolerance.

Another significant patent is her method and apparatus for producing fiber pulp in a steam pressurized environment. This invention allows for the production of pulp from moisture-containing lignocellulosic materials, such as wood chips, which are ground in a pressurized steam environment. The ground pulp is then propelled into a cyclone for separation from the steam, allowing for efficient recycling of the steam in the pulping process.
