table :
After alignment, pin and bolt the slide rails to the
foundation.
If no belt guard is included in Alpine's delivery scope,
the drive has to be equipped with a protection
corresponding to the directions for accident prevention.
WARNING
Pay attention to the data given in para. 3.2 and on the
machine.
The maximum speeds should not be exceeded!
Direction of rotation
- Sieve grates:
If the machine is equipped with sieve grates, the
direction of rotation of the beater system employed is
optional .
If the sieve insert of the sieve is a rasp-like sieve,
the direction of rotation of the beater system should be
selected so that the beaters move towards the sieve
apertures and the ground material can pass through the
sieve without deflection.

Fig. 3: Baffle-ribbed grinding track: direction of
rotationin and contrary to the conveying direction
- Triangular-shaped grinding track:
The direction of rotation against the short edge is used
when processing hard, brittle materials.
Generally speaking, this results in a finer product than
selecting the direction of rotation against the long
edge
.
The direction of rotation against the long edge is
preferred for softer, compressible materials which tend
to form deposits. The beater system can either be
directly reversed in the direction of rotation or, if
this is not possible (plate beater system), can be
turned by 180

Preliminarv work
Alpine 11
The machine equipment employed depends on the problem
specification.
If the material to be ground changes or if different
throughputs or finenesses are to be achieved, contact
Alpine for advice regarding a possible modification of
the equipment.
- Check kind and condition (wear) of the machine
equipment.
Pay attention to the accident prevention directions!
Exchange grinding track, beaters, beater system,
studs, stud discs or sieve if necessary.
- When closing the mill door, or when installing the
Cover ring, grinding track, or sieve, clean the sealings
and contact surfaces.
Pay attention to tight fit when fastening these
elements.
- Turn over the grinding media and check for ease of
movement
.
- Check the product collecting system.
Selection of the crrindinq media
- general advice -

315 UPZ - 1122/3E
Alpine 11
5.2.1 Grinding medium
To be chosen according to the grinding fineness:
- stud discs produce the finest material
- the fan beater system with long and short grinding
track is used for the medium to fine fineness range
- beater disc for coarse grinding.
5.2.2 Grinding tracks
By choosing the appropriate grinding track, the grinding
finenessis, too, influenced.
With the baffle-ribbed grinding track, the grinding
fineness depends upon the angle of the baffle ribs (10°
or 30°), the rebound direction and the perforation of
the sieve insert (if a sieve insert is used).
To ensure that the mill is provided with the
corresponding equipment for optimum operation, we
recommend to contact Alpine, mainly in case of a
modification of the problem specification or product
to be processed.
5.2.3 Grinding track variants
The following are available:
Baffle-ribbed grinding track 30° long
Baffle-ribbed grinding track 10° long
with discharge gap (to order)
7.5
/ 13.5 / 23 / 33 and 42 mm
Baffle-ribbed grinding track 30° short with sieve
Baffle-ribbed grinding track 10° long with sieve
Triangular-shaped grinding track with large pitch
Triangular-shaped grinding track with narrow pitch
with discharge gap (to order) 7.5 and 13.5

5.2.4 Sieve
Easily flowable material6 which contain few fines and
have a granular or gritty structure, are optimally
produced by using the beater disc and sieve; for this
application, the speedusually has to be considerably
reduced.
5.2.5 Air throughput
The highest air throughput is used for the fan beater
system; a medium air throughput is available with the
swing beater system, whereas the air throughput is
lowest when using the stud disc and beater disc.
Referring to the equipment of the mill, the air
throughput is approximately proportional to the speed.
For the size reduction of heat-sensitive products, the
fan beater system is ideally suitable.
The high air flow allows an effective cooling of the
product and size reduction media.
The effects of the air throughput on the operating
characteristics have to be tested in every individual
case.
Pay attention to the accident prevention directions!
Start the plant according to the switching-on sequence.
Then start product feed and slowly increase up to the
maximum, permissible load.
Observe the ammeter.

315 UPZ - 1122/3E
Alpine II
5.4 Hode of o~eration
Pay attention to the fact that no foreign matter which
could damage the grinding media is contained in the feed
material.
Note:
Feed the product to the machine as constantly as
possible
- use an appropriate feed rating device!
Check the feed rate by means of the ammeter.
Too high a feed rate might cause blocking of the mill.
WARNING
In case of overload (blocking, stalling), stop the
machine immediately.
Pay attention to the directions for accident prevention!
Open the machine.
Clean the feed duct and the grinding chamber.
Check and clear the cause.
Check ease of movement of the grinding system, pay
attention to eventual damage; repair if necessary.
Close the machine.
Stop the product supply.
Keep machine in operation until all product being in the
machine is ground.
The current consumption decreases to idling value (appr.
40%).
Stop the drive motor.
Stop the plant according to the interlocking scheme.
In case of a longer shut-down period, Open the machine.
Pay attention to the directions for accident prevention!
