Overview
The implementation of this 66 percent increase in capacity via a retrofit of the existing conveyor (with a horizontal length of 255 m and a vertical stroke of almost 44 m) was enabled with the use of high-performance rollers from Rulmeca. The challenge was to increase throughput via a retrofit at minimum investment cost.

Rulmeca designs and manufactures guide rollers for conveyors to limit the possible side-slip of the belt and keep its alignment.
For such large conveyors such as OCC's Rulmeca provided a very wide variety of components which are precisely matched to the particular conveying task. In detail the following components from Rulmeca's bulk material transportation belt roller range in the design of the OCC conveyor were used. PSV1 series rollers (20F, 108N, 323) with a pitch of 1.3 m are used on the carrying side.
Rulmeca's high-performance idlers are crucial for reliable long-term operation of such large conveyors with increased throughput. Compared to simple rollers of inferior quality, they run much more smoothly, and this reduces thermal stress. In addition, they also contribute significantly to lowering overall ownership costs. This is because they have a much longer service life than simple lower-quality rollers, and they also ensure the high reliability of the entire system due to their lower failure rate. These quality products are manufactured from precision-turned components. Especially hardened steels and other alloys ensure that the conveyor belt rollers function optimally over a long period of time and under the toughest conditions. Various protective measures for the bearings and minimal concentricity tolerances are paramount for the longevity of the bulk material conveyor rollers. Rulmeca achieves maximum precision by balancing each individual roller. It is understandable that this has its price. This investment in quality is all the more worthwhile given the higher speed and greater length of the belt.
