6.8 Continuous feeding of source material
The volume of continually fed source material may not
exceed the volume of the inserted collecting vessel.
To feed larger quantities of a free-flowing source material, use the vibra-
tory feeder "LABORETTE 24".
n
Set the feeder on a stand next to the variable speed rotor mill so
that the end of the channel is located above the funnel.
n
Connect the devices by plugging the connection cable supplied with
the LABORETTE 24 control unit into the connection socket on the
back of the PULVERISETTE 14 premium line.
If the motor is overloaded, the sample flow is interrupted.
As soon as the source material contained in the grinding
chamber has been processed and the motor runs at nominal
load, the sample flow is resumed.
The flow of source material on the feeder is regulated via the PULVERI-
SETTE 14 premium line.
The flow of the source material out of the funnel onto the channel of the
LABORETTE 24 channel has to be adjusted according to the flow proper-
ties of the source material.
n
Set the distance between the funnel and the channel by changing
the height of the funnel so that the "right" amount is fed.
n
If too much is fed, the feeder switches off automatically too often -
slide the funnel somewhat downwards.
n
If too little is fed, the load display remains in the lowest range - slide
the funnel somewhat upwards.
