Gold Mining Trommel Screen

Trommel screen is a washing and screening equipment. It is widely used in mines, gold mining plant, beach placer, sand washing plant, slag metal recovery and so on.


Product introduction
Trommel screen is also known as drum screen, gold mining trommel or trommel gold washing plant, it is a washing and screening equipment for classification according to the particle size of materials, can be used for dry screening and wet screening. Compared to the circular vibrating screen, the advantages of trommel screen are: in the same volume, the cylinder area is larger than the vibrating screen flat area, so the effective screening area of the cylinder is larger, so that the material can fully touch the screen, therefore, the unit time of the screening capacity is larger. And because of its compact structure, easy installation, easy layout and convenient discharge collection. It is widely used in mines, gold mining plant, beach placer, sand washing plant, slag metal recovery and so on.

The gold mining trommel screen provides a simple, efficient and economical screening solution for all kinds of materials, it also provides optimization treatment for the subsequent processing. This solution helps reduce operational processes and reduces investment costs and improves product quality, while allowing rapid and large volume processing. After screening, the material can be directly fed into a variety of separation equipment, such as gold centrifugal concentrator, spiral concentrator, jig machine and shaker table etc.

Trommel screen working principle
The trommel screen is mainly composed of motor, reducer, cylinder, gear, roller, discharge trough, spray pipe, sealing cover (when dust prevention is needed), frame and other parts. The cylinder is aslope mounted on the supporting roller of the frame. The cylinder is equipped with high manganese steel woven screen or high manganese steel punched screen. The motor drives the gear to rotate through the reducer, thus driving the cylinder to rotate together. When the material enters the cylinder, the material moves along the direction of rotation of the cylinder. Fine particles go through the sieve hole and discharged from the discharge trough, while coarse particles move forward until discharged from the tail of the cylinder. In the operation with water, the water spray pipe located in the center of the cylinder is used to flush the materials to prevent blockage and clean the materials. Materials of different particle sizes are gradually screened and separated along with the rotating cylinder, so as to complete the screening work.
