TRADITIONAL DRY SCREENING MACHINE

Derrick® Dry Sizing machines have been providing the industrial minerals industry solutions for fine dry screening application for over 60 years. Traditional Derrick dry sizing machines have utilized high speed, low amplitude, vertical elliptical motion to solve countless difficult mineral sizing challenges. Derrick’s commitment to pioneering technology has resulted in the recent evolution of dry screening technology to include dry sizing machines designed to utilize true linear motion to achieve higher capacity with small floor footprints, to include dry sizing machines that utilize an alternate parallel-to-flow screen panel tensioning system (“Front-to-Back” tensioning) to achieve higher capacity within the traditional Derrick machine footprint and to include a new series of Derrick Polyweb® urethane screen panels to provide long life, anti-blinding surfaces. Numerous machines can be found worldwide screening silica sand, iron powder, nickel powder, crushed glass, coal, polyethylene pellets/resins and many other materials.
