Correct use
• Use
The A10 basic is a batch mill that allows for both impact milling and cutting milling.
Impact milling:
For use with hard, brittle material, dried material or material that is brittle because of cold (for example grain,
coffee, etc.).
Here the grinding material is reduced by means of a
beating rotor. The grinding material is thus broken up.
The granularity of the final product is determined by the
duration of the grinding, the level to which the container is filled and the physical properties of the material
being processed.
Cutting milling:
For use with soft, fibrous grinding material (for example
hay, paper, etc.).
Here the grinding material is cut by means of a rotating
blade. In this case as well, the granularity of the final
product is determined by the duration of the grinding,
the level to which the container is filled and the physical
properties of the material being processed.
Intend use: Tabletop device
WARNING

• Range of use (indoor use only)
- Laboratories - Schools
- Pharmacies - Universities
This equipment is suitable for use in all areas except:
- Residential areas
-
Areas that are connected directly to a low-voltage supply
network that also supplies residential areas.
The safety of the user cannot be guaranteed:
- If the instrument is operated with accessories that are
not supplied or recommended by the manufacturer
- If the instrument is operated improperly or contrary to
the manufacturer’s specifications
- If the instrument or the printed circuit board are modified
by the third parties.
The mill is not suitable for grinding
wet material with too much water.
Otherwise, the water may leak from

Useful information
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 grinding 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 therefore 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 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. 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 materials, 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).
Following is a list of some materials that can be reduced:
Leaves, fibers, hops, cardboard, paper, hay, plastics, tobacco 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 explosion (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.
®
,
Cutting milling:
The A10 basic with the A10.2 star knife 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.
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.
Fig. 3

Fig. 4
Then, tap water could flow into the device as cooling water from either hose.
17
Page 6
Note: only water (max. 40 °C) could be used for coolant
and water pressure should less than 1 bar for the instrument. After the grinding, please ensure the cooling water
is completely empty from the cooling chamber.
Cooling with tap water is usually sucient for substances
which become hot as a result of the grinding operation
and thus are given to smearing or those that produce oil.
The grinding chamber may only be filled halfway especially when samples containing oils and similar materials
are ground.
Note: Moisture in material that is ground may evaporate
because of the material temperature increasing. Then, the
evaporated moisture will condense and flow out from the
drain hole at the bottom of the instrument.
This could prevent the motor from damage of moisture.

Please follow the safety instructions.
Crushing causes the mill feed to heat up. This may not always be desirable as the mill feed can change when heated (e.g. increased oxidation, loss of moisture, evaporation
of volatile components, etc.).
It may only be possible to crush mill feed which is viscous
or has a high fat content by embrittling using coolants.
The A10 basic offers following cooling processes:
First put the feed product into the grinding pot and then
add crushed dry ice.
Thoroughly mix the dry ice with the mill feed.
Only attach the chamber cap when the dry ice is completely vaporized, otherwise high pressure may build up in
the grinding chamber.
Please note that the mill feed heats up again extremely
quickly during grinding (it may reach room temperature
again after approximate 10 seconds of grinding). You may
have to repeat the process several times if the product is
not adequately ground after one cooling process.
Fig. 5
If more refrigeration is required, the ground matter should
be cooled prior to being put into the grinding chamber.
Grinding dust may also leak out from this drain hole during grinding process.
