Conventional HEIN, LEHMANN screening machines offer the ideal solution for all standard applications. The bolted/welded construction with unbalanced shaft or unbalanced motor drive keeps the maintenance expenses low and provides a long service life.

The well-proven construction is also approved in detail:

  • Cross bars extensively machined to bore-hole gauge result in a low-tension structure.
  • All types of screening panels from our own manufacture provide an optimal combination between machine and screen medium.
  • Extensive utilization of standard parts and an intentional avoidance of more complex designs enable low-cost maintenance.


UK_DD_seitlich_Lupe_b4a5aBoth, single-deck as well as double-deck screening machines are available as circular or linear oscillating screening machines.
Possible panel variants are e.g.:

  • Wire cloths
  • Harp screens
  • Polyurethane screen panels
  • Exchange systems
  • Wedge wire screens

The construction sizes start with approx. 3 m² up to approx. 16 m² per deck. Special designs, such as units with dust protection, complete the program.

DUK_DD_seitlich_Lupe_a9924Especially the DUK design series in particular offers solution options for even higher efficiencies and capacities, also in case of difficult to screen materials:

  • A double-shaft drive results in a more uniform oscillation mode over the entire length of the machine
  • Operating frequencies adjusted by means of a frequency converter enable an exact adjustment to the operating conditions
  • Higher accelerations cause a more intense screening output than in the case of conventional screening machines
