More than 40 years ago, HEIN, LEHMANN introduced a revolutionary new concept for classifying materials – the construction of the first Flip-Flow screening machine.
LIWELL® screening machines are the result of a continuous technical development of this concept.
They combine application-oriented practical innovation with the experience of more than 2500 successfully operating machines.
The HEIN, LEHMANN name has become synonymous with the best product of this industry.
Our standard type for normal applications with linear movement of the screen cases – well proven for many years.

Machines of type LF are available as single- or double-deck machines. Single-deck types have a screening surface from 1.25 m2 up to 27 m2, double-deck machines from 2.5 m2 up to 19.4 m2 per deck.

We can also discuss manufacturing of customised sizes.
