Working principle:

after the material enters the drum device, due to the high speed rotation of the drum, the material turns over and rolls on the screen surface, and the qualified material is discharged from the bottom of the rear end of the drum, and the unqualified material is left in the drum, so as to achieve screening. the material rollover also prevents screen clogging.
Scope of application:
Soil treatment:Screening treatment of topsoil, excavated soil, muck, contaminated soil, clay, peat, bark, compost materials, etc.
Construction waste treatment:Demolition of waste, construction waste, milling asphalt, glass and other waste sorting and screening.
Ore treatment and screening:Screening of gold, coal, jade ore, smelter, oil shale, limestone and other mineral materials.
Sand and stone treatment:Mountain sand, river sand washing operation, suitable for sand, mixing station, construction site and other conditions with more mud content.
Pipeline backfill:Circuit pipelines, oil pipelines, gas pipelines and other underground pipe networks after digging screening backfill.
