Adopting foreign technology, ore washing machines have single layer or double layers circular sieve to classify two to three kind different grades sand and stone which should be clearly de-slimed. It is mainly used for washing ore before beneficiation operation system, and improving the ore grade for next processing step. It can be used for manganese ore, iron ore, limestone, tungsten, and silica ore, and etc.
Washing barrel is supported by four tug supports, which is rotated by motor driven at the low speed. The aggregate with mud pie and stone powder from feed opening into the rotating drum, continuously brought along and thrown away by rubber wearing plate installed with certain angle in washing barrel, circulated many times during moving process from feed side to discharge end, and washed by straightforward or sensereversing rinse water. Finally, the clean aggregates are discharged after being sieved and dehydrated by shaft screen at discharged end, and the waste water with sludge is discharged from the baffle with hole at discharge end or feed end.
