The equipment is mainly for the mine and metallurgical material washing. The structure consists of three sections. The front section is the washing section, where the mud and ore are separated from each other by mutual friction through the trommel rotation with highpressure water injected to wash off the slime. The middle section is the screening section, where the ore is screened into two size fractions (>50mm, <50mm), < 50mm sized ore is discharged out through the screening bar. The back section is for the largesized ore discharge end. The equipment can work both for washing and screening and capable to process lump ore.
