摘要： A centrifugal impact crusher has an enclosed table (22) to ensure that substantially all the material deposited on the table is impacted against the anvils (50) that surround the table. The table includes spaced-apart upper and lower plates (34, 28) that have radially oriented impellers (36) sandwiched between them to direct material being thrown off of the table by centrifugal force to exit the table at the proper angle to achieve maximum fracture upon striking the anvils (50). The impellers (36) have projecting tabs (38) which fit into receptacles (40) in the upper and lower plates (34, 28) and the plates are squeezed together to hold tabs (38) in the receptacles (40) and lock the plates and impellers together in a rigid table assembly (22). The upper plate (34) has a central opening (49) through which material is deposited onto the table. A funnel (60) directs material fed into the crusher through an infeed plenum (59) and into the central opening (49) in the upper plate (34) to ensure that all of the material reaches the table. Recirculation plenums (68) extend from an outlet plenum (51) located below the table up to the infeed plenum (59). The rotating table (22) acts as a fan which draws air into the infeed tube (58) along with the material, and this airflow creates a pressure differential across the table that causes air to flow through the recirculation plenum (68). The recirculation air includes dust and particulate matter which is either sent back through the crusher to be more finely crushed or is removed by filters.
