The safety of the user cannot be guaranteed if
the appliance is operated with accessories that
are not supplied or recommended by the manu-
facturer or if the appliance is operated improperly
contrary to the manufacturer’s specifi cations or
if the appliance or the printed circuit board are
modifi ed by third parties.
This device is suitable for use in all areas, except
industrial areas.
• Use
The area of application for the universal mill is
very extensive, the list of materials which are ca-
pable of being ground and indicated here is not
exhaustive. The scope of application can be ex-
tended furtherby grinding attemps with the res-
pective grinding method and setting the approp-
riate grinding parameters (rotor speed, fi lter hol
diameter, sample preparation e.g. cooling).
Impact grinding:
The hammer mill crushes soft, medium-hard and
brittle materials to approximately. Mohs hardness
6 (feldspar: 6 Mohs, quartz: 7 Mohs). With gre-
ater hardness the wear on the grinding tools is
much higher and grinding is therefore unecono-
mical.
Anything can be ground that breaks, is dry does
not contain very fatty materials.
The following is a selection of substances drying
to grind: grain, barley, corn, malt, pectin, roasted
coffee, nutshells, bones, ergot, coal, charcoal,
coke, peat, ash, cellulose, drugs, artifi cal ferti-
lizers, refractory clay, feed, spices, glass, resin,
potash, cores, salts, cinders, stones and soil (bau-
Correct use
xite, gypsum, limestone, dry clay, mica, graphi-
te, pumice stone, gneiss, magnetite, heavy spar,
sandstone, brown iron ore, etc.).
The scope of application can be further enhan-
ced through embrittlement of the ground ma-
terial (e.g. with dry ice and/or liquid nitrogen).
Tough ground material must be cooled, e.g.
crushed dry ice put into the grinding funnel.
The ground material must be coarse-crushed
into maximum 10 mm chunks beforehand.
Note: With abrasive materials (e.g. stones or
glass) it will be necessary to clean the dosing
sluice repeatedly because settles grinding dust in
the guides and it thus rotating the dosing sluice
is no longer is possible.
Cutting-Grinding:
The cutting-grinding mill cuts up bulky, elastic, fi -
brous, cellulose and soft materials. Mixing mate-
rials such as various types of waste must be free
of iron and non-ferrous metals. The feedings may
not be damp and greasy, as they will otherwise
stick to the grinding surface and fi lter.
The following is a list of the materials that may
be processed: Leaves, fi bers, spices, grain, hop,
wood, pasteboard, paper, hay, straw, plastics, to-
bacco, peat, feed, pasta, roots and branches, etc..
The scope of application can be further enhan-
ced through embrittlement of the ground mate-
rial (e.g. with dry ice and/or liquid nitrogen).
Bulky material is metered with the tubular sli-
de valve, the feed grain size should not be not
greater than 15 mm. Bulky materials (e.g. plas-
tic bags) are metered by means of plungers, but
the pieces should not be too large (e.g. pieces
of fi r wood: max. diameter 10 mm, max. lenght
40 mm; pieces of foil: max. width 30 mm, max.
lenght 100 mm).
