Maintain original profiles is of utmost importance to have cement mills operating with highest performance, therefore hardfacing regularly with high wear resistance flux cored wires (IBER 450) is the most flexible and adequate solution for this type of mills. Reverse roller segments could be only a temporary solution.

Before and after: Picture shows hi-chrome roller segments that have been used and rotated. The yellow wear measure template clearly shows the difference of wear on the roller before and after the in-situ hardfacing has been carried out by IBERMILL. The shape and final result will be very accurate, and the profile is as close to the original profile as possible regardless of whether it’s an OK, ATOX or FRM Mill. Typically, the wear rate decreases by 50% (compared to wear rate of Hi-Chrome), meaning that the life time (running hours) of the roller normally doubles.

In case of spare parts availability, hardfacing the roller tires in the workshop and the grinding table in-situ, could be a very interesting solution.

ROLLER PRESS
ON SITE AND WORKSHOP

Hydraulic Roller Press units have been developed for material grinding, anyhow, most of the cement plants use HRP unit before ball mill for pre-grinding, saving energy and increasing capacity. Roller shafts are made of solid forged body or with shrink fit sleeve, provided with a renewable multiple layer of deposit welding. Surfaces must be rewelded when the wear protection layer worn out.
