Hello

The problem of choosing a trommel can obviously differ depending on whether it is mobile or fixed equipment.
For mobile equipment, the road gauge imposes certain dimensional constraints, which we do not necessarily have in the case of fixed screens.

Diameter and length determine the screening surface and therefore the throughput, all other things being equal.

The length determines the residence time of the product in the trommel, and therefore influences the quality of separation.

The diameter is generally for mobile equipment fixed at the maximum possible with regard to the road gauge.
For fixed trommel screens it is sometimes determined according to the size of the largest incident objects, the space available if this is limited, the mode of feeding etc.

The drive system must permanently ensure the perennial rotation of the ferrule, even for dense products such as earth, rubble, or sticky products such as sludge compost for example. The latter, because they tend to obstruct the mesh, tend to increase the weight of the product in the shell and therefore can cause an overload of the drive system.

It is therefore necessary to provide a good margin of safety in terms of torque, traction of the motor system also: for example the dimensioning of the rollers if the drive is done by the carrier rollers. If it is done by chain, here too precautions are required, in particular for the dimensions of the chain and the motor pinion (duplex chains also in certain cases).

The speed of rotation of the trommel is also an important parameter: it must be continuously adjustable, and the smaller the diameter, the more the speed is generally slightly increased.

The vibrating screens offered by Vercom are available in two and three fraction options, these screens can screen compost, woodchips, biomass, woodchips, gravel, rubble, soil, and many others. elements. Screening of these products is achieved with very reasonable operation and maintenance costs.

Vercom offers different models, from the E15 version for the smallest vibrating screen to the E100 for the largest. Calibration grids are available from 5 to 150 mm, for 100% electric screens or with an optional generator. The screens can be found in a cradle, box, trailer, and fixed electric version.

The sweepings include a significant mineral part: sand, dust, small pebbles or gravel, etc. apart from organic fractions (wood, foliage, various organic debris, etc.) and a fraction consisting of various waste and varieties left on the pavement.

The purpose of screening is most of the time to separate the mineral fraction which constitutes a marketable product for embankments and under the basement of roadways or car parks for example.

The mesh used during this separation oscillates between 8-12 mm. The most common screening technology is the trommel screen. Quarry vibrating screens can also be used in certain cases, especially if the substrates are very dry.

The company TERRA-SELECT offers interesting solutions of trommel screens with mesh shapes adapted to this use, misting systems for the fight against the release of dust, separators of the light fraction (which can go in CSR) integrated at the screener.

The wood fraction can again be separated later during a new treatment using an air separator combined with a tangential roller and also recovered in boiler rooms. TERRA SELECT also has interesting solutions in its range, both fixed electric and mobile diesel for this recovery stage.

Hello, there are suction systems on the refusals or on the useful fraction.
