Trommel Screen Introduction
Trommel screen is a kind of screening equipment commonly used in gold dressing process. Through the continuous rotation of the trommel screen, large pieces of waste rock can be thrown out, thus saving the time of sorting operation and greatly improving the efficiency of the next sorting operation of alluvial gold ore.
The placer gold ore is similar to the placer tin ore, deposits in the hillside, the river bed, the lake coastal place, forms the certain enrichment, its has the industrial mining value, is called the placer gold deposit. In general, the monomer dissociation degree of alluvial gold ore is high, only the trommel screen is used to screen out the large piece of gold-free waste rock, and the gold deposit is deposited on the sticky gold cloth, and a good index can be obtained.
The drum device is tilted and mounted on the rack. The motor is connected by a reducer and a drum device through a coupling to drive the drum device around its axis. When the material enters the drum device, due to the tilt and rotation of the drum device, the material on the screen surface is flipped and rolled, so that the qualified material (sieve product) is discharged through the outlet at the bottom of the back end of the drum. Unqualified materials (sieve products) are discharged through the outlet at the end of the drum.
- sieve holes are not easily blocked.
- runs smoothly and the noise is low.
- structure is simple and maintenance is convenient.
- sieve drum can be closed, easy to close dust collection.
- high reliability, one-time investment is less.
- special screen, high screening efficiency, long service life.
