Translation of "Siebverfahren" in English

Any grinding and sieving method satisfying the quality criteria may be used.

Dry separating methods, such as screening methods or sifting methods, are preferably used as the separation method.

The more accurate separation (for example length) compared with conventional screening methods is visible.

However, not every screening process is suitable for the delicate tea leaves.

Special, egg-formed balls are being used in the sifting industry.

The invention relates to a sieve apparatus, a supplemental device for a sieve apparatus, as well as a sieve process.

This allows more accurate separation of the fragments according to the respectively desired parameters, compared with conventional mechanical screening methods.

The linear screen combines a gentle screening process with highest screening precision and optimal screening and energy efficiency.

A further drawback of screening methods is the high risk of the screen becoming blocked, due to the irregular grain shape of the silicon fragments.

By using vibrating or oscillating sieves of this type, the screening or classification of the sieve product, i.e. the sieve process itself, is embodied in a more effective and efficient manner.

SUMMARY OF THE INVENTION By comparison, the object of the present invention is to create an improved sieve apparatus and a supplementary device to increase the sieve efficiency, as well as an improved process for sieving, which should improve efficiency and effectiveness during sieving.

The method according to the invention may include any desired hitherto known screening steps, for example, wherein screening with vibrating screens is preferred because the separation is especially good.

As part of the manufacturing process, any adherent dust particles, agglomerates and overlengths are screened out using a special screening process in order to achieve the desired particle size and product quality.

Here you can see a movie how our screening bucket works compared to other methods to screen material.

A product having a defined particle-size distribution or bulk and tapped density can be obtained by an optional subsequent sieving process.

Following comminution, the chunk polysilicon is typically classified or sorted by a mechanical screening method or by means of optical sorting.

In order to determine the grain size, a multiplicity of processes can be used, for example screening processes, sedimentation processes in water columns, light scattering processes (for example, scattering of laser light), or similar.

Furthermore, according to an additional embodiment, the method is conducted such that starting material with an average particle size greater than 1 mm, in particular from 5 to 40 mm, is used (the particle size here is determined by a sifting method).

Methods suitable in principle for determining particle size are, for example, screening methods, sedimentation methods and methods based on the diffraction or refraction of electromagnetic waves, especially of light.

Methods that are suitable in principle include, for example, screening methods, sedimentation methods and methods based on the diffraction or refraction of electromagnetic waves, especially of light.

Fillers of the desired grain size can be obtained in various ways, for example by special precipitation methods, combustion processes, etc., but also by mechanical comminution, in which case, if necessary, all these processes can be coupled to a fractionation or screening process.

The particle-size distribution and the mean particle size can be determined using methods such as sieves or granulometers (e.g. manufactured by Silas) which are familiar to a person skilled in the art.

So, the JEL Freischwinger offers many advantages for operators who are looking for a screening process that is gentle to their delicate products.

Bigger-scale particles can be separated by the always applied screening process following the reduction, but the smaller particles remain in the tungsten powder.

The new screening process was supposed to be as gentle on the product as possible, so that the pellets (in particular the coated variety) would not be damaged.

The base for this product is the magnetic foil 0,4 or 0,3 mm and the print (on the foil or paper) is done in the screen or offset printing process.

Before PMMA is ready for delivery for the processing industry, dust particles, agglomerates and overlong pieces adhering to the cylindrical granules are sifted off in a special screening process in order to attain the desired particle size and/or quality of the granules.
