Estimating the term…
A centrifugal impact crusher has an enclosed table to ensure that substantially all the material deposited on the table is impacted against the anvils that surround the table. The table includes spaced-apart upper and lower plates that have radially oriented impellers 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. The impellers have projecting tabs which fit into receptacles in the upper and lower plates and the plates are squeezed together to hold the tabs in the receptacles and lock the plates and impellers together in a rigid table assembly. The upper plate has a central opening through which material is deposited onto the table. A funnel directs material fed into the crusher through an infeed plenum and into the central opening in the upper plate to ensure that all of the material reaches the table. Recirculation plenums extend from an outlet plenum located below the table up to the infeed plenum. The rotating table acts as a fan which draws air into the infeed tube along with the material, and this airflow creates a pressure differential across the table that causes air to flow through the recirculation plenum. 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.
