Dynamic Screening Technology

Managing Directors, Mr Martin Eves & Mr Patrick O’Toole in conjunction with known screening specialist Mr Ralph Naberg bring to the market a new concept for an extreme energy screening machine. Mr Naberg has more than 50 years’ experience in engineering and vibration screening technology. Mr Eves and Mr O’Toole have over 40 years’ experience in the screening and reprocessing industry in Europe, Australia and USA.

While traditional screening technologies are based on the acceleration of the vibration motion to approximately 3 G-Force, DSS Ltd have scientifically developed the technology to achieve up to 10 G-Force. A combination of expertise, knowledge and high end engineering gives DSS Ltd the ability to harness and control these extreme dynamic forces in the creation of the new SST & MST screening machines.

Our Screening Technology

  • Unique vertical acceleration approaching 10 G-force and three times the vertical acceleration of traditional screens.
  • Three variable speed synchronised drive shafts deliver a high energetic circular motion over the complete screen length.
  • Engineered in single and double deck formats.
  • Low maintenance costs.
  • Simple mechanical functionality.
  • Screen mats to suit the individual customers’ cut size requirements.

Features | Dynamic Screening Technology

Subject to individual product testing, dynamic parameters can be adapted to suit different customer requirements. i.e. different product = different configuration.

Accurate calculation of the relationship between amplitude, speed and inclination slope.

Customer specific pre-set configuration allows for the fine tuning of the machine to best suit individual material requirements.

High screening power means the screening material receives an intense breakdown due to the impact force of vibration. More particles are screened efficiently at an early stage on the deck, giving increased screening capacity.

An understanding of particle movement combined with high energetic screening allows control of the impact/launch points across the complete length of the screen deck without flexing. A traditional screen’s vibrating movement completes one rotation cycle per particle throw, while a DSS screen completes three rotation cycles per particle throw. There is minimal slipping of particles due to their straight vertical contact, thus reducing wear of the screen mesh.

Traditional screens use 2 – 3 motors/drive systems in a combination of ‘with flow & counter flow’ directions to achieve separation and transport of the particles on the screen deck. The new high energy Dynamic Screening Technology achieves a much higher separation of the particles in a ‘with flow’ configuration using a single motor.

The driving mechanism with synchronised drive shafts is separate and not attached to the vibrating machine itself, therefore allowing the screen body freedom of movement without restriction.
