Description

Technical Field

[0001] The utility model relates to the technical field of screening machines, in particular to a screening machine for construction materials of a building project. Background Art

[0002] During construction, a screening machine is needed to screen the sand and gravel used.

For this reason, we propose a screening machine for construction materials. Utility Model Content
