Coarse aggregate processing line is the use of hydraulic washing or additional mechanical scrubbing to separate the ore from the mud. Common Equipment ore washing screen, drum washing trommel machine and trough ore washer.

Washing operations are often accompanied by screening, such as washing directly on the vibrating screen or sending the ore obtained by the washing machine to the vibrating screen. Screening can be used as an independent operation to separate products of different granularity and grade for different purposes.

The technological process of dealing with aggregate oxide ore is generally crushing the ore to 6 ~ 0 mm or 10 ~ 0 mm, then classification, jigging at the coarse level and shaking at the fine level. The gravity separation equipment is mostly Haz reciprocating mineral jig and 6-S type shaking table.
