Rotary trommel scrubber to wash nickel ore or bauxite ore

Description of rotary trommel scrubber

Rotary trommel scrubber , also known as drum washer, is one kind of heavy mineral washing machine, often used for clean the mineral for removing the clay or pebbles. Rotary trommel scrubber is generally consist of two part, namely scrub part and screen part, for large heavy model, also use two - stage scrubbing, two - stage screening structure.

When the material is fed into the scrubber, it will be flushed by the high-pressure water spray, then fully soaked in the slurry section, to make the clay soft and separate from mineral; during the rotation of drum, the minerals keep rolling and rubbing each other, thus strengthening the washing function and making the mineral surface cleaner. The cleaned material is discharged by the screen part, then divided into different size. Then complete the washing job.

In the application of rotary trommel scrubber, the washing purpose is vary with different minerals. For example, to process bauxite ,the cleaned mineral is obtained and remove the clay; to process nickel laterite ore, the gravel in the silt will be cleaned and removed.

In the ore washing , two –stage washing process is generally adopted to meet the requirements of the downstream process. The rotary trommel scrubber is widely used as the first-stage washing machine, it should do two things in this process: one is separate the small size ore which is below 50mm or 20mm to the second-stage washing process as soon as possible; the other is keep the enough washing time for the big size mineral or waste rock, so as to clean the big mineral or waste rock fully
