| Abstract: | Circular mould will be seriously weared when alfalfa powder pellet sharped by the extruding from feedstuff circular mould pellet.A new three-body abrasive wear testing machine had been designed to stimulate pelletizing condition in order to explore wear mechanism of circular mould invalidation.The tester have heat and corresponding control system,windage of temperature less than 2 %.It could be used in abrasive experiment between alfalfa powder and different metallic samples under about 100 ℃ temperature. |
