Introduction for Desliming Rotary Drum Screen Mineral Separator RXT series Drum rotary scrubber is mainly used for clay mineral washing and desliming so as to improve the dressing performance in the next process. It is widely used not only for manganese ore,iron ore, limestone, tungsten ore, and silica sand, but also for high clay. It is able to effectively crush the clay lumps and make the raw ore to be incomplete looseness in the scrubber part, and remove the useless stones at once at the end screening part, and thus effectively increase the high clay gold recovery rate. Working Principle for Desliming Rotary Drum Screen Mineral Separator ï?·The slurry material feeds into the drum where it is vigorously scrubbed, the soil matrix is broken up and the taaarget mineral is released. The material is then screened through the rotating screen and waste is ejected. The screened material is then passed on to the concentrating modules for upgrading.
