ATOX MILL CONCEPT
• THE THREE CYLINDRICAL
ROLLERS ARE RIGIDLY
CONNECTED TO A COMMON
CENTERPIECE
• THE GRINDING PRESSURE IS
EXERTED HYDRAULICALLY
THROUGH THREE PULL RODS THROUGH THREE PULL RODS
ATTACHED TO THE OUTER
END OF EACH ROLLER SHAFT
• THE ROLLER ASSEMBLY IS
KEPT CENTRED ON THE
GRINDING TABLE AND
PREVENTED FROM ROTATING
BY THREE TORQUE RODS
ATOX MILL
ROLLER LOADING ARRANGEMENT
• SIMPLE, LIGHTWEIGHT LOADING
ARRANGEMENT ENSURES THE
LOWEST POSSIBLE INERTIAL
REACTIONS TO GEAR AND
FOUNDATION PARTS
• AS THE GRINDING FORCES ARE • AS THE GRINDING FORCES ARE
TRANSMITTED TO THE
FOUNDATIONS DIRECTLY
THROUGH THE TABLE AND PULL
RODS, THERE IS NO NEED FOR
HEAVY ROCKER ARM/MILL STANDS
• THE MILL BODY AND SEPARATOR
ARE SUPPORTED INDEPENDENTLY
FROM THE VERTICAL LOADS OF
THE GRINDING SYSTEM
ATOX MILL
REPLACEMENT OF WEAR PARTS
• SEGMENTED WEAR PARTS FOR BOTH ROLLERS AND TABLE ALLOW USE OF THE MOST WEAR RESISTANT MATERIALS WITHOUT RISK OF CRACKINGOF CRACKING
• ROLLER SEGMENTS CAN BE REVERSED ENABLING HIGH MATERIAL UTILISATION TO BE ACHIEVED ALSO IN CASE OF UNEVEN WEAR

The picture illustrates a "red river"
in the left hand side of a Folax
cooler.
The transport direction in the
picture is from right too left.
The picture was taking from the
man door just after the first grate
more or less corresponding to the
end of the recuperation zone.
“Red River”
In the right hand side of the cooler
(bottom of picture) some big lumps
of clinker can be observed. The
combination of lumps and fine
clinker is a nightmare as big lumps
leaves you with a high clinker
temperature, the red river are
mechanical damaging and both
destroy the heat efficiency.
The location was a cement plant in
Canada, before the first grate was
converted to CFG. Now the cooler
has been converted by CPAG
