Flip Flow

The new “Flip-Flow” elastic mesh screens type SN-FF with polyurethane meshes are designed for the screening of problematic materials. This could be due to excessive mois-ture, low density or materials with a tendency to get caught in the meshes. In particular materials which cannot be screened efficiently with other technologies such as rotary screens, conventional vibrating screens, etc.

Equipped with a sub resonant frame that amplifies the vibration of the main frame, resulting in acceleration on meshes of up to 50 G.

The screening surface is made of high density polyurethane panels. These panels are mounted on separate modules which vary in size depending on the product to be screened and mesh opening needed.


For some applications where different types of screening is required, the “Flip-Flow” can be combined with different types of screen surfaces either on the same machine or as a set of two machines. With the advantage of separate machines being the ability to combine different vibration frequencies and amplitudes appropriate to each screening surface and product.

Screening with a “flip-flow” is usually combined with these other types of screening media:

  • Conventional metal mesh
  • Rigid polyurethane panels
  • Metal bars
  • Holed plates


The applications where these screens are used are becoming more numerous but include among others:

  • Urban solid waste
  • Used tires recycling
  • Biomass
  • Metals
  • Used cars recycling
  • Expired food
  • Expired drugs
  • Construction waste recycling
  • Glass recycling
  • Slags from incineration
