[0002] The concrete slurry as the raw material of the aerated concrete block is generally a kind of artificial stone formed by cement, sand, stone, water and other additives after mixing, stirring and curing hardening according to a certain proportion. The aerated concrete block is widely used in construction engineering due to its light weight, porous, heat preservation, heat insulation and good fireproof performance.

[0003] In the production of aerated bricks, the required raw materials are relatively fine, so it is necessary to filter the sand and stone by means of a screening drum. The screening drum generally includes a feeding hopper and a screening drum body. The feeding port of the feeding hopper is upwardly opened, and the discharge port is connected with one side of the screening drum body. In use, the earthmoving machine excavates the sand and stone raw materials, and the sand and stone raw materials are sent into the feeding hopper through the front bucket, and then into the screening drum body for screening.
