The invention discloses an air-added brick production system and a production process thereof, and belongs to the technical field of building bricks. The air-added brick production system comprises a slurry producing device, a powder producing device and a pouring device; the slurry producing device comprises a feeding mechanism, a wet grinding mechanism, a filtering mechanism and a temporary storage mechanism, and slurry filtered by the filtering mechanism is directly led into the temporary storage mechanism; the temporary storage mechanism is externally connected with a slurry discharge pipe and a slurry pump to pump the slurry to a slurry tank; the powder producing device comprises a crushing machine, a dry grinding mechanism and a screening mechanism, and a powder tank is communicated with a pouring tank through a conveying mechanism arranged at the bottom of the powder tank; and the pouring tank is downwards connected with a pouring spray pipe, and a pouring vehicle is arranged under the pouring spray pipe. The aims that internal particles of a finished air-added brick are even, no large particles influencing the stress uniformity of the air-added brick exists, and the internal hole size is even are achieved. The problems that the air-added brick ingredient adding amount is small, the kinds are many, mixing is not uniform during adding, and therefore the air-added brick quality is influenced are solved.
