The setting of the gap between the push-fit chute and the feed hopper depends on
the maximum particle size of the feed material. It should be about 3 times as large
as the max. particle size.
• Press the ON/OFF switch (DN) on the DR100 .
• Turn on the sample divider and start it.
The DR100 does not start until the sample divider has reached the nominal speed.
The DR100 switches off automatically when the nominal speed of the sample
divider varies too much or drops. If this fluctuation lasts only for a short time (<5s),
the DR100 switches on again once the nominal speed has been reached again
and the feeding process is continued. As soon as you stop the sample divider, the
DR100 stops too and the sample is not fed.
