The up-and-down pouring device is a key unit of the AAC block pouring machine. It comprises pouring nozzle, lifting arm, and air compressor cylinder. It is mounted below the pouring mixer and is connected with the PLC control system.
After mixing, the obtained slurry will be poured into the empty moulds. The number of big air bubbles in the mould is reduced and the AAC pouring area could be kept clean. In addition, due to the adopting of up-and-down pouring device, the oil layer on the inner wall of the mould can be prevented to a large degree, thus the green cake won’t stick to the mould when being turning over.
