<p>An aeration assembly comprises a sequence controller 11, a suction pipe (inlet) 12, an outlet discharge pipe 13, an air exhaust pressure regulator 14, a vacuum/pressure pump 15, an electric motor device 16 and an input/output flow control valve 17. In operation, slurry is sucked into the tanker through the valve 17 and is aerated by air from the pump 15. When the aeration has been competed, the pump is used to expel slurry through pipe 13 and into the store 20. <IMAGE></p> |
