Multifrequency sieve for separation of difficult particles

Separating particles in difficult-to-process materials for processes in the food and chemicals industries can be inefficient and time-consuming. Utilising vibration technology to sieve such materials gives vastly improved performance, and the latest technologies mean even greater productivity is now available.

Patented vibration technology sieve for maximum performance

The Virto X-Line circular range has been specifically designed to handle difficult materials with increased performance over traditional vibratory sieves.

Offered with a single deck (CS) or double deck (CD), the circular X-Line is tailored to suit your specific requirements and is offered in three distinct size models ranging from 650 mm diameter to 1,200 mm diameter and

The CS  uses a patented system developed by the manufacturer known as MFVexcite. This technology converts traditional single-frequency oscillation into a multi-frequency movement. Thanks to this development, the material acceleration transmitted to the mesh reaches 500G, instead of the 5G delivered by standard sieves. This means class-leading performance of up to 99% particle purity in materials that are difficult (or traditionally impossible) to screen, sticky, abrasive or agglomerative.

Manufactured to high quality standards, is offered in stainless steel with many accessories such as motor covers, different types of connections, stands, pneumatic lifting system, clean-in-place systems and with gas purging. All contact parts can be customized with a mirror polish finishing.

Because it uses two motors operating in synchronisation at lower speeds, the CS uses less energy than traditional vibratory sieves, reducing running costs and increasing lifespan.


  • Class-leading screening capacity and efficiency, with 99% particle size purity
  • Gives the ability to screen the most difficult materials, including sticky, abrasive and fine
  • Consumes less energy than standard units, with extended mesh life, for lower running costs
  • Wide range of options to tailor to your exact requirements
  • Reduces process costs by eliminating waste


With operations starting nearly 70 years ago, Cuccolini/Virto Group(  is one of Europe’s largest manufacturers of screening and separation equipment producing up to 3,500 vibrating sieves a year for more than 65 different industries (ranging from fine food, pharma and metal powders to heavy aggregate and mining material) across more than 75 countries.
