Xclass® - Magotteaux's new patented CPT2 lining

Cement

Ball mills - 2nd compartment

The Xclass® concept includes 2 plates : one base plate and one support plate with its deflector. Base plates protect the shell while deflectors, organized in a spiral shape, classify the media.

* DIN drilled shell (250x314mm) or similar with a diameter range from 3.00 to 4.6m (as of today).
* Unit weight of Xclass® plates range from 21 to 25kg (as compared to 40 to 56kg with traditional classifying liners).
* Deflectors can be switched 180° and therefore start a second lifecycle. This allows for constant classifying efficiency during the lining's lifecycle.

* Liner weight reduced by 20 to 35% depending on mill diameter. E.g. for a mill in the 4.4 to 4.6m diameter range, weight is reduced by 465 to 310kg/m².
* Xclass® allows for an increase in useful diameter of mill, ranging from 40 to 76mm depending on mill diameter. As a consequence, ball load may increase by
0.9 to 2.5 tons per meter of EGL (Effective Grinding Length), which, in turn leads to an increase in absorbed power.
* One single bolt type.
* Reduced maintenance operations -> Reduced costs.
* Potential time and manpower savings during installation.
* All Xclass® plates available from stock.
