The Cross Beater Mill SK 100 comfort is suitable for
coarse and fine size reduction, either in batches or continuously.
It can process medium-hard and brittle materials with a hardness
of up to approx. 6 on Mohs’ scale. The SK 100 is intended
for universal use: from sample preparation in laboratories and
industrial plant, through pilot installations up to preparing
batches in production facilities.
The cross beater mills are
mainly used for reducing the size of:
- cement clinker
- coke
- glass
- gravel
- minerals
- ores
- oxide ceramics
- slags
- soils
and many other similar materials.
The maximum feed size for bulk
goods is 15 mm, for single-piece
feed 20 mm. The final fineness and
throughput depend on the breaking
behavior of the feed material and the
aperture size of the bottom sieve.
Due to the powerful drive it is possible
to achieve a fineness <100 μm in
a single working step in many cases.
The SK 100 comfort is distinguished
by its extra operating comfort and
standard of safety. The grinding
chamber door can be opened and
closed quickly and simply with its
quick-action lock. This means that
changing the bottom sieves and
cleaning the grinding chamber hardly
take any time at all. If the quick-action
lock is accidentally opened then
a safety switch activates the motor
brake, so that the rotor comes to a
standstill in less than 0.5 seconds.
The feed hopper is equipped with access
barrier and splash-back protection.
The cross beater mills are robust
and maintenance-free and compl
with the CE guidelines. Their highquality
finish also guarantees that
the mills will have a long working
life. |

| Size reduction in cross beater
mills takes place by hammering,
impact and shearing effects. The
feed material passes from the
hopper directly into the center of
the grinding chamber, where it is
caught by the cross beater and
ground between the baffle plates
of the cross beater and the
toothed grinding insert. As soon
as the material is smaller than the
aperture size of the bottom sieve
used, it passes through the sieve
and enters the collecting receptacle.
The air drawn in through the
hopper by the cross beater accelerates
the discharge of the ground
material. The airborne fine fraction
is separated off by a downstream
filter system. |
The mill housing is made from cast
aluminum. Depending on the particular
version (see table) the grinding
insert and grinding tools are made
from different materials. The choice
of version depends primarily on the
feed material. Chrome steel is recommended
for hard feed materials,
stainless steel for corrosive ones.
Baffle plates made from steel 1.1740
can be used for heavy-metal-free
grinding.
Bottom sieves made from trapezoid
or round hole sheet are available in
14 aperture sizes. For heavy-metalfree
grinding bottom sieves made
from steel St 1203 are available in
6 aperture sizes.
The standard equipment supplied
with the cross beater mills includes a
stainless steel collecting receptacle
(5 l) and a textile filter hose. The mill
can be attached to a bench or a wall
bracket; however, it is preferable to
mount it on the optional base frame.

The standard equipment supplied with the SR 200, SR 300 and
SK 100 comfort includes a 5 l stainless steel collecting receptacle
and a textile filter hose. By using the filter hose between the mill
and collecting receptacle the flow of air produced by the rotating
rotor is led away and back-pressure is avoided. It also accelerates
the material throughput and ensures a gentle size reduction process.
Instead of the textile tube a ring-type filter made from stainless
trapezoid hole sheet (aperture size 63 μm) can be used with or
without a dust filter unit; this is easier to clean, particularly with
fine dusts, and ensures a higher stability for the collecting receptacle.
If larger amounts are to be processed we recommend the use of
the electromagnetic Vibratory Feeder DR 100 for uniform material
feed and the 30 l collecting receptacle with the corresponding filter
hose.
Mills SR 200 and SK 100 can be mounted on a workbench.
However, it is preferable to mount them on the optional base
frame.
