Flip-flow screens, also known as flip flop or elastic mesh screens, are machines designed to efficiently screen sticky, wet, and other difficult materials. Flip-flow screens are used in a number of industries to separate everything from aggregate and minerals to inhomogeneous recyclables, construction waste, and...

Material Recovery Facilities (MRFs) play a vital role in waste management, scrap processing, and the recycling industry. MRFs specialize in separating, sorting, and ultimately preparing recovered materials for sale to an end buyer. However, increasingly strict international regulations have made recycling contamination a growing concern for...

Properly sizing a screen requires consideration of key material and machine characteristics, along with desired product specifications. The interplay of these factors will determine the proper machine for the application, the screen media and the efficiency of the machine. Mechanical screening is much more complicated than...
