Abstract: A high speed particle packaging machine comprises a weighing station, operable to weigh a cluster of particles. A densification station is positioned downstream of the weighing station and is operable to collect a cluster of particles recently released from the weighing station to densify the cluster of particles. The densification station includes an openable gate operable to instantaneously release the cluster of particles collected at the densification station. A bagging station is positioned downstream of the densification station and is operable to receive the densified cluster of particles after being released by the gate.
