In simple words, a trommel is mining equipment comprising of a cylindrical drum that has many holes of a given size. The holes help in classification, and when the drum rotates it only lets the material smaller than the holes fall through while the rest of the material flows out of the other end of the trommel. Trommels are widely known and used popularly around the world on various sized mining operations
Miners worldwide commonly use gold trommels. In a gold trommel, gold-bearing gravel is added to the hopper and it enters the rotating drum that further helps to break apart the material. It is used to help separate and classify out the material for further processing, so as to separate the smaller gold bearing material from the larger substrate like rocks, pebbles and boulders. These can be manufactured in any size to suit the needs of the miner
On larger operations, the trommel is generally incorporated into an entire wash plant setup. Generally speaking, to efficiently operate a trommel, two people are required. One person would feed material into the trommel and the other one would clear any discharged waste material so that more material can be fed into the machine
As mentioned above, Trommels are widely used in gold mines, since they are extremely efficient and very effective at recovering fine gold. The larger-sized models can handle impressive volumes of gold-bearing gravel when operating at peak efficiency. They are often powered by large diesel or electric engine
Let us understand in detail how a gold trommel works and how efficiently it can be operated. To begin with, once the trommel is set up, the motor starts rotating the cylindrical drum, the water sprayer also gets activated. Gold-bearing material is added to the hopper and the force of water washes it down or cleans it to break up the material and help separate the gold. The drum keeps on moving round and round. Any pieces of material (rocks and gravel) larger than the drum screen hole size are forced down the drum into the tailings bucket and out, forming a coarse tailings pile at the bottom of the unit. The rest of the gold-bearing gravel falls into the sluice box below, where hydraulic action helps to trap the black sands and gold while allowing the waste to flow out the lower end of the box into additional tailings (fine tailings). Here is when the other person cleans the sluice box. Finally, the concentrates are then run through a concentrator where the gold is recovered
Since the goal is to completely break apart any clays and mud that could retain placer gold and prevent it from being caught in the sluice, different designs and amounts of water jets are used. It is basically, high-pressure water together with the rotating drum which breaks apart any clays and dirt as the slurry moves through the drum
