The casing (28) supports a series of fixed (18, 26) and moving (22) blades, the latter rotating about their lengthwise axes and having their outer radial ends adjacent to the casing's inner surface. It has a main component and a cellular plate opposite at least one set of moving blades. The plate has tubular or honeycomb cells and a cover on the opposite side to the blades, the cover having holes linked to some of the cells while closing others. Some of the closed cells contain a wear material of resin or glass balls, and the assembly also has a perforated metal sheet between the cover and the main component of the casing.</p> |
