Useful Information - IKA A10 basic Mode D'emploi

The mill can be used in a wide range of applications. The
list of grinding materials given below is not complete.
It is possible to expand the range of applications further by
means of grinding experiments with corresponding grind-
ing procedures and sample preparations.
Impact milling:
The A10 basic with a beater reduces soft, medium hard
and brittle materials with a Mohs' scale of hardness of
up to 5. For greater levels of hardness, the wear and tear
on the pulverization tool is very high and grinding there-
fore becomes uneconomical. If the A10 basic is used for
grinding materials with hardness greater than 5 Mohs, the
A10.3 hard metal beater, which is more resistant to wear
and tear, must be used. This prevents the sample from be-
ing 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. Following is a list of substances
that can be ground dry:
Wheat, barley, corn, malt, pectin, roasted coffee, nutshells,
bones, ergot, peat, pharmaceutical, fertilizers, feed materi-
als, spices, resin, potash, seeds, salts, cinders, tablets.
Tough grinding material must be cooled, for example by
adding pulverized dry ice to the grinding pot.
The grinding material must be initially broken down into
pieces with a feed size of 6 mm (the size of a grain of corn
is ideal).
Cutting milling:
The A10 basic with the A10.2 star knife reduces bulky,
elastic fibrous and soft materials with high cellulose con-
tent. 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.
Working with cooling water:
There are two hose couplings located at the bottom of the handle in order to connect the cooling water. Connect hoses
as following:
- Remove the low part of the handle
- Connect the hoses to the couplings (we recommend hose Ø 8 x 1,5 mm).
- Fix the hoses to the couplings with included clips.

Then, tap water could flow into the device as cooling water from either hose.

Useful information

Following is a list of some materials that can be reduced:
Leaves, fibers, hops, cardboard, paper, hay, plastics, to-
bacco and roots.
The feed granularity should be no bigger than 10 mm.
Note: Materials that are not listed above should only be
reduced in the A10 basic after confirmation from IKA
especially if there is uncertainty about the danger of ex-
plosion (dust explosion as a result of electrostatic charge).
Working with the A10.4 grinding chamber reduction:
When the sample is very light or the sample quantity is
very small (1- 5 ml), the user can insert the A10.4 grinding
chamber reduction into the grinding chamber for grinding
as shown in Fig. 3.
