APPARATUS AND METHODFOR MIXING MATERIAL

摘要

A mix for batch mixing a treatment agent and a particulate material comprises a mixing chamber having at least one mixing member rotatably mounted therein. Outlet means is positioned to receive the mixed batch of material from the mixing chamber. The mixing member may be rotated at a first speed of rotation effective to mix materials within the mixing chamber without discharging from the outlet means. The mixing member is also rotatable at a second speed of rotation effective to discharge the charge or batch of material through the outlet means after it has been treated during the initial mixing step. The rotation of the mixing member at a higher rate of speed at the second speed of rotation effects discharge through the outlet means by centrifugal force.
