Trommel machines are popular in gold mines and construction sites. They are used to separate solid materials of different grades. Rather than manually picking the different materials, these machines automatically sieve through the small grade particles leaving the large particles in the trommel. Here is a detailed guide on how a trommel screen works.
A trommel machine is a cylindrical rotating screening plant used to screen materials of different grade sizes. The screen can be fitted with bars inside to aid in breaking the material to the required size. The mixture of material to be separated is first added to the hopper. This is the receiving part of the trommel machine. If there is a need for water to break down the mixture, you can customise your hopper with water jets.
From the hopper, the material then enters the rotating screen. A trommel machine is an entire machine while the screen is the cylindrical drum. The amount of material that enters into the screen depends on the size of the drum. It is important to note that the size of a trommel machine is defined by the size of the screening drum. Here, the materials can be subjected to water if there is a need to break them down.
The drum is made of screen material. The screen allows smaller gravel to pass through to a processing system or sluice while larger gravel remains in the drum and is moved through the drum and discharged at the end. Although screen sizes vary, the most common sizes are ½” and ¾”. A properly working screening machine will have separated all the fine materials by the time the large materials are discharged at the back.
How are trommel machines made?
Trommel machines are not hard to make. However, you need the various components of the machine to assemble one. If you have the assembly skills, you can purchase the different parts and fix them on your own. However, it is recommended to involve a professional to install a properly working trommel.
The first step to a quality trommel is to purchase high-standard trommel parts. There are hundreds of suppliers providing trommel screens. However, make sure that you find the best screen for purchasing from a reputable dealer.
The next step is to choose the right trommel size. This includes the length, circumference of the cylindrical drum and size of screen holes. The length of the trommel depends on the available space. Choose a trommel that will perfectly fit in your property. The size of the screen holes will depend on the size and nature of your material.
Finally, trommel screens are efficient and long-lasting. However, this depends on how you maintain and run them. Before you add material to the screen, make sure it’s the right material for that specific trommel. The screen should effectively rotate without a struggle.
Running a trommel machine is easy. Once powered up, all you need is to switch it on and off. There are static and mobile trommel machines. Choose the right type based on your needs and purpose.
