Virto-Cuccolini vibrating screens: filtration as a versatile solution for multi-sector applications


Virto-Cuccolini’s vibrating sieves are emerging as a transformative influence in a constantly shifting industrial panorama. Clearly showing a significant versatility beyond their traditional role in separating solids and powders, the vibrating screens also offer advanced solutions for the filtration of liquids in different industrial sectors.

Virto-Cuccolini’s sieving equipment has set a new standard in liquid filtration. Their ability to efficiently handle liquid filtration has elevated their status within the industry. Their utility extends beyond solid particle separation, to include essential roles in the treatment scheme of industrial waters and process fluids.

Virto-Cuccolini’s vibrating screens proficiency in filtering solid particles is supported by recent tests which confirm their ability to filter particles below 100 microns, delivering high performance levels without necessitating pre-filtration steps that could otherwise lead to system overload.

Application tests were performed in the agricultural biomass sector for digestate filtration in fertilizers and biogas derivate production; in the alcoholic beverage sector, and also in the produce food production, as a measure to treat waste fluids derived from manufacturing processes. The goal is to minimize wastewater treatment and disposal costs and, where feasible, recycle the filtered liquid back into production lines.

    As we could observe over time, Virto-Cuccolini vibrating screens have always been synonymous with quality as used screens too.

    Among the reasons that customers give for choosing one of our used sieves compared to those of other brands, we have for example the fact that, obviously if well maintained, a Virto-Cuccolini screen can last even twenty or thirty years. We can also confirm this through the requests for spare parts that reach our Aftermarket Division!

    If you are planning to buy a used Virto-Cuccolini industrial sieve, here are some simple recommendations:

    – Check that the identification plate with the serial number is present; it will be useful to require us information where necessary

    – Check the year of production: if it is prior to 2000, it is necessary to check with our Aftermarket Division that the spare parts are still available

    – Preferably, buy our vibrating screens from companies specialized in the resale of industrial used items, because they carry out the necessary checks before their purchase and can advise you on the possible use of the sieve; Virto-Cuccolini’s Aftermarket Division staff can also support you in this verification based on your new application

    – Before starting to use your used Virto-Cuccolini screen, our Aftermarket Division is available to give you the necessary assistance to find out how it should be used, to receive user and maintenance manuals and other advice for the right adjustment

    To contact our Aftermarket Division, write to: indicating the serial number of the screen in question (and possibly attach a photo).

      One of our most well-known quality points as far as our sieves design is concerned is the way we provide that your Virto-Cuccolini C-Line sieving equipment is perfectly sealed, with the aim to avoid product leakage and dispersion inside the sieve.

      Why is sealing so important in sieves’ design?

      There are many reasons for preventing the product from leaking through the seals of the mesh support ring and/or through the deck borders:

      food product may create mustiness in case it gets stuck in some dead-end areas in the sieve

      high-value product could be dispersed if the sealing system is not working properly

      – in solid-liquid separation, a leaking design could cause loss of liquid product, apart from damages caused to the sieve itself or to the surrounding area



      During our 30-year long experience in the ceramic industry – where we had the occasion to learn how to sieve powders, granules, pastes and liquids under particularly challenging production objectives – we conceived our sealings and our general sieve design by taking care that the product is never leaking (of course, if maintenance is done correctly!) or dispersed inside the sieve.


      Maintenance of Virto-Cuccolini C-Line sealings is easy:

      – gaskets (available in silicon, EPDM and Viton) can be easily replaced

      – they are basically of 2 types: one embracing the mesh supporting ring (and holding the mesh cleaning system, when included); and one sitting underneath the deck to protect the mesh in the contact areas

      Sealing is finalized by the active presence of the installed decks and of the external fixing ring so that sealing adherence is made perfect, that dead areas with product residues are avoided, and that – in the first place – the product in the sieving area is never really getting in touch with the sealing area!

      Replacement of gaskets is suggested at least once a year, especially if the replacement of mesh rings is frequent due to the change of cut point necessary to your sieving process.

        Are you planning to include a Virto-Cuccolini sieve within your plant?

        Let’s go through some important tips concerning installation and use within a plant so that you can get out the best from Virto-Cuccolini sieving equipment and avoid later issues.

        A vibrating or tumbling sieve is a piece of equipment which – differently from any other comparable processing equipment – needs to move.

        Of course, a sieve must be firmly installed on the ground or on a suitable structure, studied to exclude resonance phenomenon both when the sieve is running dry or with the product. In case such a phenomenon appears, please consider reinforcing the structure accordingly.

        Apart from the bottom part of the sieve, which hosts fixation holes (in its basement or frame), the rest of the sieve structure is moving during the sieving process by vibration or tumbling.

        Therefore, the sieve needs to be installed in a suitable area in which no other rigid structure is present around the sieve in a position that may interfere with the sieve’ movements.

        Analogously, all inlets and outlets must have a flexible connection, in a minimum measure covering 1.5 times the diameter of the inlet or outlet (i.e. diameter 200 mm requires a flexible connection D200 with a minimum height of 300 mm). This means that feeding and discharging equipment shall remain at a reasonable distance from the sieve. Moreover, flanges are not suitable for connection; nothing shall hang from the outlets but the flexible connection alone.

        The sieve is supported by springs; in case the springs are bending or inclined, this means that something is interfering with the sieve stability (maybe some other piping) and a check around the sieve is required.

        Moreover, around the sieve, there must be enough room to allow periodical checks and maintenance. Consider for instance that the mesh supporting ring, whose dimensions are equal to the diameter of the sieve, may need to be disassembled from the machine to allow mesh replacement. With medium and big diameters and depending on the height at which the sieve is installed if not directly at the ground floor, lifting equipment may be needed to carry out this replacement.

        Another important concept to remember is that a sieve can never be used as a buffer. Meshes and their supporting ring are not engineered to support weight, but just a time-limited passage of product through the mesh. Product weighing on the mesh may cause the mesh to relax or even mesh breakage, apart from being a major disruption within the range of allowed vibrations, potentially damaging so the structure of the sieve.

        Should you have any questions concerning sieves installation, do not hesitate to contact Virto-Cuccolini and receive guidance!

          Our Virto-Cuccolini team is used to innovate while daily responding to our Customers’ requests.

          It’s exactly there, where the magic begins: one Customer’s request can indicate a need for what turns out to be a wider group of applications and our team has always in mind the opportunity to push our technology a little further.

          That’s how our Zero Gap Discharge System for C-Line vibrating sieves is born.

          The oversize product might – under some specific conditions – find it a bit harder to overcome some small gap and flow freely to discharge. Or maybe, this effort can create a transformation in the oversize product itself, and change some product features, on which quality and/or the rest of the production cycle is relying for some reason. A particularly valuable product should be even damaged in value and performance by discharge issues.

          Eliminating any gap in front of sieve discharge is therefore giving the chance to improve the sieving process under some collateral aspects like particles shape and integrity of their aspect and features.

          This week we have completed the construction of the first VPM 1200 from our C-Line range with the new Zero Gap Discharge System.

          Watch the below video to see how it works:

              Foundry sands are high-quality silica sands used for foundry casting processes.

              With the aim to supply precision during the casting phase, the granulometry of this sand needs to be homogeneous. After the casting process, sand can be reclaimed and reused.

              And that’s where Virto-Cuccolini’s tumbler comes into play!

              Watch this video to check our sieving process for foundry sand with our T-Line tumbler, the right type of sieving technology for this job! We could create here up to 3 different products with 2 cut points.

              Are you looking for a suitable solution to improve the particle size precision of your foundry sands? Please contact us by using below form and we’ll be happy to assist!

                Meshes are the heart of the sieving process.

                As fundamental as they are, they also happen to be quite delicate and need special care.

                Once a Virto-Cuccolini sieve or screen leaves our factory, meshes are out of the manufacturer’s responsibility exactly as it happens with tires when you buy a new car. A tire puncture can happen to anyone.

                So, we asked ourselves: “How to support our Customers in such a way, that they can learn and apply mesh protection measure easily?”

                We came up with creating this booklet: “Care and maintenance of sieving meshes, the core of the separation process” in 6 languages (Italian, English, Spanish, French, German and Russian), with an overview of all tips and instructions to take care of your meshes.

                Starting from this month of March 2021, this booklet will accompany our use and maintenance manuals to make sure that sieves’ operators are well aware of the care required by meshes within the sieving process.

                And should you need any further support, of course the Virto-Cuccolini team is available for any question! Drop us a line using the form here below and we’ll be happy to contact you.

                  CEO & General Manager

                  Cuccolini Srl – Virto Group

                  December 2020

                  A sieve is an ancient tool, born in agriculture, to easily separate fine products of different sizes through a mesh thanks to the simple shaking with the hands.


                  This simple technology has been transferred to the industrial world to serve the most diverse applications and still has room to spread along with production innovations.

                  From the simplicity of the agricultural sieve, Virto-Cuccolini over time has developed screens with configurations that are always adapted not only to the application but also to the specific context of use.

                  In fact, the range of Virto-Cuccolini screens includes:

                  – 3 different screening technologies to choose from the most suitable for the specific case:

                  – in each product family, models suitable for different screening objectives (safety screening, classification, dedusting, solid / liquid separation)

                  a wide range of sizes in order to satisfy the different capacity requests

                  4 different finishing levels, from basic to food (2 types) and finally to pharmaceutical

                  – an infinite range of meshes in stainless steel, nylon, polyurethane and with meshes from 7-10 microns to 2 cm, depending on the product to be screened

                  several automatic mesh cleaning systems to keep it free from clogging and always efficient

                  different methods of installing the screening mesh, also depending on the maintenance habits of each individual customer

                  more stages of separation in case of classification (from 2 to 4)

                  – variants, tricks and adjustments that allow the screen to be adapted to the behaviour of the product on the mesh to obtain the maximum possible efficiency

                  – some versions with compact dimensions that are well suited to any installation context

                  A Virto-Cuccolini sieve is not “just a sieve”: it is the fruit of the sieving culture developed by Virto-Cuccolini, which not only treasures over 30 years of industrial experience but continues every day in experimentation and development alongside our customers with an experienced team, always open to test new solutions.

                  A Virto-Cuccolini sieve is, above all, YOUR sieve: made just for you, always looking for the best relationship between price and the level of quality and performance you are looking for. Contact us to find out more using the form below!
