8 useful ways in which a Virto-Cuccolini sieve can support your production


A vibrating sieve – or more in general, an industrial sieve – is for separating product particles according to their dimension, by letting them through one or more meshes. In order to avoid any particle alteration during the process, different types of vibration or movement can be applied to the sieving system.


Separating product particles in an industrial environment can target different results, like:


1.Separating coarse particles from finer ones, in order to convey each group to a different use; this is the simplest case, applied first of all in heavy industry (aggregates, soil recovery in mining industry, industrial waste management in general); for this type of applications, Virto-Cuccolini developed a specific series of sieves with revolutionary features – X-Line – including a patented vibration system; an example for this application is available with this video:



2. Check whether the result of a granulating or milling process is as expected; and if not, separate bigger particles to be sent back to grinding/milling or smaller ones to be sent back to granulating; it is a typical sieving case that we can find in food processing as well as in waste management, which is handled by Virto-Cuccolini through the C-Line series, composed of traditional sieves, as well as with X-Line series, for building materials applications. An application sample is shown in this video, where the sieving function is applied to glass recycling:



3. Have an ingredient going through a check sieving, in order to eliminate possible foreign bodies before the product enters the production process and also to break up possible particle lumps; it is a function which is regularly required for base ingredients like flour, sugar, starch, chemical additives etc., by food or chemical industries, who need to ensure safety through avoiding that metal parts or paper/plastic particles enter the process. An example of application, typical at bags or big bags opening, is visible in this video, as carried out by a Virto-Cuccolini circular sieve from C-Line:



4. Classify powders or granules by separating them according to their size in a single action; for this function, a Virto-Cuccolini tumbling sieve is available within T-Line series; this type of sieve, initially born for sand classification in building materials production, is also applied to chemical and food products. An example of sieving classification is visible here:



5. Identify and separate solid particles within liquids in order to reuse them within the production process. In many food, chemicals or waste management applications, this separation is required in order to recirculate both liquid and particles. An example of solid-liquid separation, carried out by a vibrating sieve from Virto-Cuccolini C-Line, is available here:



6. Dedust, that is separating powders from solid particles: this is what happens in following video, where we separated pine nuts from their protective skin, already or almost detached from the nut, by using a Virto-Cuccolini tumbler from T-Line series:



7. Identify very fine particles within a powder product in order to obtain a new product to be sold to Customers. It is the case of metal powder industry, where Virto-Cuccolini particularly experimented innovation during most recent years through X-Line series:



8. More generally speaking, there are lots of other applications where a Virto-Cuccolini sieve can support you within a production process: just as an example, we can mention all processes where by-products or particles considered waste can be separated instead and reused in a circular economy process. Like in this video, where catalytic converters are separated from other metal parts, with the aim to improve their recycling, through a rectangular X-Line sieve:

    We gladly give you our answer below to make it easier for you to select the type of sieve most suitable for your application, deep diving into the characteristics of the two screening technologies.

    A rotary screen or sieve allows the screening of powder products by pushing the particles through the sieving mesh, using a screw conveyor or a rotating paddles system.

    A vibrating screen or circular screen – or also a tumbler – allows the screening of powder products through the vibration or nutation movement transmitted by the motor or nutation mechanism installed on board. No rotating part is therefore involved in the process and the particles descend by gravity through the screening mesh and following the movement impressed by the machine.

    In a vibrating screen, the absence of rotating parts brings following advantages:

    • maintenance is simpler, since it does not involve rotating parts or their accessories (bearings, seals, paddles or other similar components)
    • cleaning is easier too, because the product flow areas are spacious and easily accessible thanks to the design – completely made of stainless steel – designed to prevent stagnation
    • the mesh is more protected and not subject to stress by rotating parts
    • the noise level of a circular vibrating screen does not exceed 70 dbA, while the rotating parts might be noisier.

    In cases where greater screening precision is required, the circular vibrating screen is also more suitable, because the oversize fraction (that is, particles bigger than required cut point size) remains absolutely separated from the rest of sieved product, guaranteeing greater separation efficiency.

    A circular vibrating screen also has smaller dimensions in height than a rotary sieve. Therefore it can save space in the installation. It is capable, if appropriately sized, to reach high screening capacities. In addition, a circular vibrating sieve can also separate solid particles from liquid products, with a specific configuration.

    Would you like to evaluate the installation of a Virto-Cuccolini circular vibrating screen instead of a rotary screen?
