10.04.2017 Magnetic filter for paper pulp

Goudsmit Magnetics Group, Waalre, the Netherlands, has recently manufactured a series of magnetic filters that are suitable for removing baling wire from paper pulp. These steel wires hold bales of cellulose together and – when everything goes according to plan – are removed before the cellulose is processed into pulp. This is achieved by an automated process followed by human inspection. In practice, the process is never perfect and steel wire still occasionally ends up in the paper pulp. This causes damage to the pulp processing equipment, as well as production downtime. Placing a magnet in the paper line prevents equipment damage, downtime and therefore significant losses.  
The magnetic filters for paper pulp have a large bore for product flow, ranging from DN100 to DN400. This passage is completely surrounded with very strong magnetic bars with a high flux density, making it possible to capture the steel wire even at a relatively high flow rate. In addition, the magnetic insert is fitted with a sturdy guide and pneumatic rods, which simplifies handling for operators. This is not only ergonomic but also ensures that regular inspection takes place. This solution is increasingly finding favour outside the Netherlands, especially from large paper producers in Sweden, France and Indonesia.
