Cryogenic planetary ball mill is mainly applied to ultrafine
grinding under condition of low-temperature requested by materials.
Compared with the artificial injection of liquid nitrogen cooling,
cold-air planetary ball mill is much easier and more convenient to
be operated, it is also cost-saved, and low-energy consumed.
Cold-air planetary ball mill (with air cooling system) is composed
of planetary ball mill and air cooling device. Cycling of cold air
quickly takes away the heat generated by grinding by means of air
conditioning refrigeration principle, and temperature inside the
grinding space can be controlled at 2-10 ℃ according to temperature
difference of working environment. Such a cold-air device can be
also applied to assembly other models like vertical ball mill,
horizontal ball mill, 360 degree ball mill and dual ball mill.
Refrigeration Design
Equipped with refrigeration device equivalent to an air
conditioner.
Good Practicability
Temperature is generally controlled within 5-15 Celsius degree,
mainly used for somspecial materials which are required to be
ground into superfine powder under low temperature process.
Air cooling system
The air cooling system has advantages of simple structure, easy
operation, convenienct maintenance and low energy consumption.
Work principle
XQM series planetary ball mill with air cooling device has four
ball grinding tanks installed on one sun wheel. When the sun wheel
rotates, the tank axis makes planetary movements and the balls in
the tanks grinds and mixes samples in high speed movement. The
product can smash and blend various products of different materials
and granularity with dry or wet methods. Minimum granularity of
ground powder can be as small as less 0.1μm
Air cooling device connected to planetary ball mill with pipes,
blow cold air inside ball mill chamber to lower environment
temperature of mill jars.
Experiment on the following requirements of the Cooling Air
circulating Planetary Ball Mill:
1.The temperature needed to be lower than 50 ℃ during the grinding of
biological samples.
2.The powder will be caked in the process of ultrafine grinding.
3.In some experiments, the temperature should not be higher than 30
℃.
4.The powder will expand during high temperature grinding, which will
lead to explosion experiment
Summary: the circulating cold air ball mill mainly solves some
problems caused by high temperature and chemical reaction in powder
grinding process, and controls the temperature of grinding process
so as to obtain more perfect experimental samples.
The main fileds of Application for planetary ball mill are
- Agriculture
- Biology and Biotechnology
- Ceramics and Glass
- Chemicals
- Construction Materials
- Environmental Research
- Medicine
- Mineralogy and Metallurgy
to name just a few.
Planetary ball mills are available in versions with 2 or 4 grinding
stations. The freely selectable machine settings, comprehensive
range of grinding jars made from top-quality materials as well as
the numerous possible balls charge combinations(number and ball
size) allow individual adaption of the grinding parameters to the particular
size reduction task.
Guidelines for sample amount and ball charge
As a rule of thumb, the grinding balls should be approximately 3 x
larger than the largest sample particle. In addition to the
instrument settings and the ball size, the filling level of the jar
is also of crucial importance for a successful grinding process in
ball mills.
When grinding bulk materials, the jar should be filled with approx.
1/3 sample and 1/3 ball charge. The remaining third is the free jar
volume that is necessary for the free movement of the balls.
If an increase or decrease in sample volume is to be expected
during the grinding process, the filling levels may be changed
according to the range give in the table below (in case of an
expected decrease in sample volume, a further deviation is
possible).
For wet grinding with grinding balls <3mm the ball charge should
make up 60% of the jar volume, while the sample amount should be
30%, Then density of the grinding ball materials is used to
calculate the mass of the required amount of grinding balls.
*Please note: The maximum recommended speed should be considered
when using those grinding ball sizes, please refer to the operating
manual for further information.

Remarks:
Please note: for this TENCAN ball mill, you require two or four
grinding jars of your choice and the corresponding number of
grinding balls. The grinding jar material must be harder than the
material to be ground. In normal cases, grinding jars and balls of
the same material are used. To shorten the grinding time, larger or
heavier grinding jars and grinding balls with a higher density can
be used.
