Following is a list of substances that can be ground dry:
Grain, barley, corn, malt, pectin, roasted coffee, bark, roots, nutshells, bones,
ergot, compressed materials, peat, cellulose, pharmaceutical, artificial, fertilizers,
feed materials, spices, resin, potash, seeds, salts, slag.
Tough grinding material must be cooled, for example by adding pulverized dry ice
to the grinding container.
The grinding material must be initially broken down into pieces with a diameter of
1 cm (feed granularity 10 mm, the size of a grain of corn is ideal).
Cutting milling:
The
A 11 basic
with the A 11.2 cutting blade reduces bulky, elastic fibrous and
soft materials with high cellulose content. Mixed goods such as trash must be
free of iron and non-iron metals. The feed material must not be too moist or fatty.
Otherwise the material may adhere to the sides of the grinding container.
Following is a list of some materials that can be reduced:
Leaves, fibre, spices, grain, hops, cardboard, paper, hay, plastics, tobacco, peat,
feed goods, dough and roots.
The feed granularity should be no greater than 10 mm.
For moist and sticky feed material (for example fish, meat), reduction is also
possible by adding water. This prevents the grinding material from adhering to the
walls of the grinding container, and the blades continue to engage the grinding
material.
If water is added, the grinding container should not be
filled to more than 50% capacity. The mill must only
be used in an upright position in this case (must not be
agitated or turned on its head).
Materials that are not listed above should only be
reduced in the
A 11 basic
after confirmation from
IKA
,
especially if there is uncertainty about the danger of
explosion (dust explosion as a result of electrostatic charge).

Useful information
The analysis mill can be used for a wide range of applications. The list of grinding
materials given above is not complete. It is possible to expand the range of
application further by means of grinding experiments with corresponding grinding
procedures and sample preparations.
Impact milling:
The
A 11 basic
with a beater reduces soft, medium-hard and brittle materials
with a Mohs’ hardness of up to 6 (felsite: 6 Mohs; quartz: 7 Mohs). For greater
levels of hardness, the wear and tear on the pulverization tool is very high and
grinding therefore becomes uneconomical. If the
A 11 basic
is used for grinding
materials with hardness greater than 4 Mohs, the A 11.3 beater, which is more
resistant to wear and tear, must be used. This prevents the sample from being
contaminated by bits of the grinding tool broken off by wear and tear.
Everything that breaks, is dry, and does not have a high fat content can be ground.
