Description

Technical Field

[0001] The invention relates to the technical field of drum screening, in particular to a drum screening machine which is convenient for feeding. Background Art

[0002] The drum screening machine is a material screening equipment widely used in many fields. When the drum screening machine is screening granular and powdered raw materials, the powdered material itself is also a valuable resource, and the powdered material usually has a smaller particle size and a larger specific surface area.
