摘要: A screen comprising an annular body having screening and accepts side faces. The body includes a plurality of generally longitudinally extending screening slots projecting from its screening face through only a portion of the body thickness and a plurality of sets of accepts slots projecting from is accepts face through only a portion of the body thickness. The sets of accepts slots are each arranged along the length of one of the screening slots and each communicate with said one of the screening slots.
