Technology Strengths,Weaknesses and Critical Indicators

NOTE: There are multiple technologies that that are used as part of integrated manure management systems and yet are not manure management types on their own. The impact of these technologies on their own would be minimal or very difficult to quantify.

General Support & Other:

  • Can be an integral part of many manure management systems
  • Most projects have at least some equipment that supports operations of the main technology
  • This technology is not evaluated on its own, the NEAT Matrix for this technology is neutral unless utilized with other technologies.

Newtrient Comments/Opinions:

Designed to handle difficult solids the Shaftless Screw Conveyor represents an additional component to the Trident line. Trident has a reputation for well built equipment that works as promised and the introduction of this new component allows them to address one more problem that they have seen in the field. At this time the Trident Shaftless Screw Conveyor does not have a 9-point score as Newtrient is not aware of any dairy installations.
