TERRA SELECT Trommel Screen Machines

Perfect Separation Everywhere

Whether in landfills, composting plants, recycling centres, earthworks or forestry: the screening plants of the TERRA SELECT series are versatile and therefore a real asset, especially for municipalities and contractors. 

All About our Mobile Trommel Screen Machines:

High mobility and an enormous variety of applications guarantee you absolute flexibility when using our TERRA SELECT. Thanks to the outstanding fuel efficiency of all drive types and the fact that maintenance costs are reduced to an absolute minimum, our trommel screening machines are impressive in all areas. They therefore not only promise to make your work much easier, but can also significantly reduce your operating costs .

In Which Applications can I use a TERRA SELECT Screening Machine?

TERRA SELECT screening machines are perfect for separating a wide variety of materials and substances. These include:

  • Green waste
  • Compost
  • Soil
  • Waste wood
  • Pre-shredded construction waste
  • Household and commercial waste
  • Materials from metal processing

Our mobile trommel screens are also successfully used to separate recyclable materials from disused solar panels.

What Different Trommel Screens are Available?

We offer the right drum for every application possibility and a wide range of hole sizes for the optimum separation sharpness of your product – our selection covers screen sections from 8 to 100 mm. At the same time, the easy exchange of the screen trommels allows flexible switching between particle sizes for maximum efficiency and best results. We distinguish between different types of screen trommels for different purposes.

1) Segmented Trommels

In this version, individual wire segments are stretched around the trommel body. This technique makes it possible to create trommels with a wide variety of wire meshes for fine screening of all kinds.

We also offer customised products with a special hole size on request! Just ask us! 

2) Punched Trommels

In this version, the screen openings are punched directly into the metal. This results in trommels made from one piece, which are particularly resistant and are also ideally suited for coarse and heavy throughputs. There are different screen patterns:

  • Square holes lined up straight
  • Square holes lined up offset to each other
  • Round holes lined up offset

The round hole design is particularly suitable for separating household and commercial waste, while those with square holes function as universal trommels for a wide range of throughputs.

What Distinguishes the TERRA SELECT Models From Comparable Trommel Screen Machines?

The recycling machines of the TERRA SELECT series always have a wider trommel diameter and thus at least 10 % more screening area than comparable products. The TERRA SELECT T 50, for example, has a trommel length of 4.5 m and a diameter of 2 m – only 1.8 m is usual. This significantly increases the throughput capacity. The use of top-quality steel and thick-walled running surfaces also ensures that our trommels have a maximum service life.

Independent of the enormous throughput capacity, Eggersmann mobile machines are characterised by further standard features:

  • NRT - Noise Reduction Technology reduces the sound pressure level through a setup that is specially adapted to the machine. In the process, the values are reduced far below the standard. The result: maximum noise protection at the workplace.
  • MMS - The Minimum Maintenance System minimises the maintenance effort while extending the maintenance intervals. The machines are designed in such a way that there is no need to lubricate the bearings at all.
  • ASC - The Auto Standby Control regulates the output depending on the current workload and stress. If there is no more material in the machine's feed hopper, the engine automatically throttles down so that less fuel is consumed. 

In addition, all TERRA SELECT machines have our Eggersmann Telematic. This is a mixture of remote service and machine monitoring. On the one hand, you can have all work data, as well as location and operating material consumption, displayed live via the Internet on your PC, laptop or smartphone. On the other hand, the machine automatically sends malfunctions or pending maintenance to the responsible sales partner.

Can I use Competitors Sreen Trommels in my TERRA SELECT?

The version of the TERRA SELECT T 60 with tracks can also be optionally adapted for use with other common screen trommels in the 6 metre class. This way you can continue to use your existing trommel stock. It is best to let us know which system you require before placing your order.

What Drive Options are Available for the TERRA SELECT?

With the TERRA SELECT you can freely choose between three different drive options: 

  • Electric
    Our fully electric versions can be supplied with power via a power grid connection (Plug&Play). This makes them absolutely emission-free.
  • Electric/Diesel-Electric
    In our hybrid versions, electric motors drive the trommel, the hopper and the discharge belts. They draw their energy either from a mains connection (Plug&Play) or from the optional diesel generator.
  • Diesel-Hydraulic
    In the diesel-hydraulic versions of our TERRA SELECT, a hydraulic system is responsible for the conveyor belt drives and the rotation of the trommel. The hydraulics themselves are driven by a diesel engine.

All three drive types are characterised by particularly low fuel consumption and, at the same time, extremely low emissions. 

How does a Trommel Screen Work?

The material is fed into the feed hopper by a wheel loader, with the hopper belt monitoring and controlling the transfer to the trommel. The throughput is then defined by the constant rotational movement of the drum and the hole sizes. The finer materials fall through the screen openings, while the portion that is too large for the openings is passed on to the rear by the inner screw and transferred to the coarse grain belt at the end. This results in two fractions that are ejected via the discharge belts. The fine-grain belt discharges the material laterally, while the large-grain belt discharges it behind the machine. The size of the discharge cone can be varied by using longer conveyor belts. Any more questions? Just take a look at the mode of operation in the following video:

How can I Remove Plastic?

The pollution of the environment by films and light plastics is constantly increasing. More and more often, these contaminants are found in throughputs, reducing the quality and value of the end product. But the AIRFIX V 60 windsifter offers a solution to this problem as well. The air classifier unit is attached to the ends of both conveyor belts of the mobile screening plant and ensures underblowing and extraction of the impurities. 

Can I Also Separate Metals or Stones From the Throughput?

Metals are valuable and therefore particularly annoying as a contaminant in the throughput: For separation, there is the option of mounting overband magnets on the discharge conveyors. Powerful magnets will then remove these after the actual screening process.

For the separation of stones and other heavy contaminants, a stone belt can optionally be attached to the respective discharge belt.

Does TERRA SELECT Also Offer Stationary Screening Plants?

The TERRA SELECT series comprises mobile trommel screening machines. We offer stationary recycling machines of all kinds through BRT HARTNER. In addition to stationary trommel screens, disc screens, rotor screens, ballistic separators and much more are also available there.

What is the Difference Between a Drum Screen and a Trommel Screen?

Technically, we differentiate between screen drums and trommel screens with regard to the material transfer within the drum. A trommel screen stands horizontally and the material is conveyed to the outlet by a screw or spiral as the trommel rotates and the material is thrown inside the trommel. A screen drum, on the other hand, has a pre defined incline and the material therefore automatically falls further and further forward as it is thrown up. Our partner BRT HARTNER offers with the SD and the ST a stationary screen drum as well as a stationary trommel screen.
