The main applications of the newly engineered vibratory screeners for separation of problematic wet and dry materials include safety screening and sizing classification of ‘difficult-to-screen’ materials, typically in the range between 20 and 500 microns. Screeners have single or double-deck design and come in 2-, 3- and 4-feet diameters. The screeners operate in multifrequency vibratory-impact modes, providing uninterrupted self-cleaning of the meshes, fluidization of powder, and de-agglomeration of powder clusters. It results in higher screening capacity, better separation and more undersize yield especially when compared to traditional and ultrasonic screeners, according to the manufacturer. The units are designed for use with non-tensioned working meshes. Screeners offer simple, cost-saving on-site sieve replacement using pieces of nylon, polyester or stainless steel meshes which simply cut-off from a roll. This feature eliminates the costs and problems that are usually associated with re-tensioning of conventional and ultrasonic fine screens. The systems are simple, easy-to-use, rugged mechanical devices that provide low-cost maintenance and yield improvements. Unlike ultrasonic or conventional separators, the screeners do not contain electronic or pneumatic parts. The Patented powerful de-blinding system is completely mechanical and is activated from the vibratory motors.
