Description

Technical Field

[0002] Roller screen is a kind of equipment widely used in river cleaning, stone sorting and other working conditions in the field of mine sandstone, tailings field and construction waste treatment field. It has a unique effect on screening high-moisture and high-viscosity materials. It is also called mud and stone separator and butterfly screen. Its working principle is that the motor drives the linkage shaft with irregular shape. The screen surface is composed of multiple linearly arranged rotating bearings. There are the same screen plates on the roller. The roller is rotated by the gear drive chain. The rotation direction is consistent with the flow direction of the raw material. The irregular wear-resistant device between the shafts supports the forward movement of large-particle materials.
