the filter which you ordered.
The delivery quantity for the cutting-grinding head includes: a cutting-
grinding head with three built-in bed knives, built-on door, tabular slide
valve and funnel, as well as three screwed-in attaching pins, a plunger, a
blade rotor with three mounted rotor blades, a cheese head screw, a disk
and the filter which you ordered.
Important information
The MF 10 analytical mill is a continuously operating universal mill. It
makes it possible to use two different grinding methods which cover the
greatest range of all grinding tasks occurring in the laboratory.
Impact grinding:
Application for hard, brittle and/or dried materials or ground materials
embrittled as a result of cold (e.g. grain, coffee, coal, etc.).
In this case, the ground material is cut up by means of rotary beaters and
comminuted on the grinding surface attacherd to the blow bars. The gro-
und material is broken and ejected into a suitable collecting pan by
means of corresponding filters. The feed dosage provides for optimal
dosage so that the mill can work at the optimal operating point. The grin-
ding chamber is locked so that it is dustproof, the collecting pans are
attached with standard ground joints. Thus the loss ground material is
kept to a minimum.
Cutting-Grinding:
Application for soft fibrous ground material (e.g. hay, straw, plastic
waste, paper, wood, etc.).
In this case, the ground material is cut between rotary blades and stan-
ding blades attached at the grinding surface. The ground material is con-
veyed into the collecting plan by means of filters here as well. The feed
unid (guide channel) makes it possible to load awkward, bulky material.
The cutting loads mean that less energy is introduced into the ground
material and thus results in less heat generation. This keeps ground
material loss to a minimum.

Proper use

The area of application for the universal mill is very extensive, the list of
materials which are capable of being ground and indicated here is not
exhaustive. The scope of application can be extended furtherby grinding
attemps with the respective grinding method and setting the appropria-
te grinding parameters (rotor speed, filter hol diameter, sample prepara-
tion 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 greater hardness the wear on the grinding tools is much higher and
grinding is therefore uneconomical. Anything can be ground that breaks,
is dry does not contain very fatty materials.
The following is a selection of substances drying to grind:
ley, corn, malt, pectin, roasted coffee, nutshells, bones, ergot, coal, char-
coal, coke, peat, ash, cellulose, drugs, artifical fertilizers, refractory clay,
feed, spices, glass, resin, potash, cores, salts, cinders, stones and soil
(bauxite, gypsum, limestone, dry clay, mica, graphite, pumice stone,
gneiss, magnetite, heavy spar, sandstone, brown iron ore, etc.)
The scope of application can be further enhanced through embrittlement
of the ground material (e.g. with dry ice and/or liquid nitrogen). Tough
ground material must be cooled, e.g. crushed dry ice put into the grin-
ding funnel.
The ground material must be coarse-crushed into maximum 10mm
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, fibrous, cellulose and soft
materials. Mixing materials such as various types of waste must be free
of iron and non-ferrous metals. The feedings may not be damp and grea-
sy, as they will otherwise stick to the grinding surface and filter.
