Aggregates Screening

MAKE AN ENQUIRY

Virto Group’s diversified product portfolio has a strong history of fulfilling the needs of many clients that offer aggregate and quarry products to the construction industry. Both of our product lines, Cuccolini and ScreenX have many case studies for particle separation of materials in these aggregate industries including sand, crushed sand, quartz sand, crushed quartz, limestone flux, calcium carbonate, crushed limestone, dolomite, granite, marble, clay and more.

It is renowned across all aggregate industries that the most common reason for lost production is the blinding and pegging of the mesh on screeners due to the dry aggregate materials becoming wet from humidity or rain. This has traditionally been solved only by waiting four or five days for the material to dry out because conventional screeners cannot separate below 5mm due to high natural humidity content . However, Virto’s unique ScreenX line of industrial sieves has proven its ability to overcome this due to its multifrequency vibrating technology that transfers up to 500G of acceleration in to the mesh which causes it to self clean and deagglomerate fine, sticky and humid material.
