Abrasion protector for particulate conveying fluid ducts has anti-abrasive cover layer with relief surface

摘要

The abrasion protector for a wall (3) abraded by a particulate carrying fluid has a combination of an anti-abrasive layer (2) and a relief surface (4) of which the partitions (9) are perpendicular or obliquely to the wall. The difference in height between the upper plane (7) of the relief surface and the lowest point of the of the layer creates loss of charge in the conveying fluid. The relief surface is incorporated in the anti-abrasive layer.
