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
