The feed hopper (1) is suitable for manual feed of
the sample material by hand and for automatic feed
of the sample material with the DR 100 feed unit
(33) (Fig. 24).
With the DR 100 feed unit (33) , larger quantities of
sample material can be fed automatically. When
feeding large quantities of sample material,
operation in combination with the cyclone separator
(29) and a collection receptacle (30) (Fig. 25) is
recommended.
