Cutting mill:

Assembling the cutting mill head:

Attention!

The blades on the rotor and in the grinding

chamber have sharp edges. Both parts should only be han-

dled when wearing protective gloves.

The ON/OFF switch Pos. A 13 must be to zero and the pow-

er supply plugs must have been disconnected out before

beginning assembly of the cutting-grinding head.

First the three threaded bolts Pos. S 12 (see ﬁg. 2) are

screwed out to the same hight (distance between hexagon

of the bolt and the ﬂat surface on the grinding head is ap-

proximately 2 mm, this corresponds to two turns). Make

sure that the ﬂange piece on the drive and on the head

are clean and free of dust. Abrading both ﬁtting parts with

a slightly oiled rag facilitates assembly. The head is now

pushed onto the drive, while making certain that the parts

do not jam. The threaded bolt ends must ﬁt into the drill-

ings of the transmission cover. Thus the head has be rotated

slightly in a clockwise direction. After the bolts are ﬁtted

in the head is turned until it is stopped by the bolts and so

that the head now stands upright. Now close and clock the

grinding chamber door with the operating knob Pos. S 9 (3

to 5 revolutions are sucient). This ensures that the grind-

ing chamber is optimally aligned so that the door can be

easily opened and closed later.

Now the screw mountings are tightened with the fork

wrench provided. Make certain that the pins are tightened

toward the head (see ﬁg. 3.2).

NOTE: Tighten the pins evenly!

Now the hammer rotor Pos. S 20 can be installed. For this

the ﬁtting key Pos. A 7 is ﬁrst inserted into the groove of

the drive shaft Pos. G 6, make certain that the groove is free

from dirt and dust here as well. The rotor is pushed onto the

drive shaft as shown in Fig. 2, fastened with the disk Pos. S

22 and the cheese head screw Pos. S 21. The countersunk

screw, P 15, is tightened with the Allen key supplied, while

the rotor is held with the face spanner that is included in

delivery. The spanner is positioned so that the pins of the

spanner are inserted into the bore holes on the face of the

rotor. The disc must be turned so that the bore hole in the

rotor is accessible for the spanner pins.

Note! After tightening the cheese head screw with the Al-

len key, turn the blade rotor once (360°). The rotor may not

touch. Repeat assembly if necessary.

Now the ﬁlter Pos. Z 1 that is suitable for the grinding pro-

cedure can be inserted; to do so the ﬁlter is pushed into

the grinding chamber from the front. The ﬁlter and the

ﬁlter holder surface in the grinding chamber must be free

from dirt and dust. Now the grinding chamber door can be

closed and locked with the operating knob Pos. S 9. The

screw mounting of the operating knob is screwed in by

pressing and twisting it into the internal thread on the drive

cover. The ﬁrst turns are easy, if turning becomes dicult

then the door may be closed, but the safety switch is not yet

unlocked. Continue turning until stop (approximately two

revolutions), only then is the safety switch unlocked and the

mill ready to start.

Grinding operation with the cutting mill:

The suitable ﬁlter is pushed in and the door is locked before

beginning the grinding procedure.

Afterwards a collecting pan is fastened to the discharge cone

Pos. S 1 (standard ground joint NS 29). Suitable containers

are e.g. Erlenmeyer ﬂasks Pos. Z 3, round-bottomed ﬂasks,

test tubes made of either glass or plastic. The containers are

to be secured with a ﬁxing clip Pos. Z 2 (see ﬁg. 2).

For heat sensitive materials or with ground materials that have

a very high increase in volume during cut up, it is advisable to

use a erlenmeyer ﬂasks with ﬁlter attached to its second (e.g.

cotton wool, etc.). The ground material is cooled from the air

ﬂow and no excess pressure is created. for very critical ground

materials (very ﬁne powder after being cut up) the ground ma-

terial can also be sucked off by means of a commercial vacu-

um cleaner with a suction tube adapted at the discharge cone.

The powder is then in the vacuum cleaner bag where it can be

removed for further processing steps.

The speed knob Pos. A 12 is turned to the left stop (3000 rpm).

The mill is started by shifting the rocker switch Pos. A 13 to Po-

sition 1. First the green „Power“ LED is lit and then „Overload“

LED lights up brieﬂy before the motor smoothly starts.

The speed can be set by turning the speed knob to the de-

sired speed. A speed up to 5000 rpm is recommended for

cutting-grinding while higher speeds should only be selected

in exceptional cases (e.g. greater energy requirements such

as for dry pieces of wood. The optimal speed must be de-

termined by way of experiment. The higher the speed, the

greater the cutting-grinding power. However, more energy

is introduced into the ground material and thus the thermal

load is increased.

The lunger Pos. S 6 has to be removed from the guide chan-

nel before the ground material is fed in through the funnel

Pos. S 5. Make certain that the tubular side valve Pos. S 8 is

closed. Bulky materials can be simply filled into the funnel.

Metering is carried out by lifting the tubular slide valve.

Bulky material should be fed into the guide channel with the

tubular side valve closed and the plunger must be fitted to

in front of the tubular side valve in order to prevent chunks

of ground material from spurting out.

The plunger may only be pulled out when the motor is run-

ning if the tabular side valve is closed.
