Applications in the cement industry
A hammer clinker crusher breaks down large clinker pieces before they are ground into cement in an enormous ball mill – with the aid of optibelt SK S=C Plus installed with a tight length tolerance without the need for measuring.
In the last step, the cement is packed and stacked on pallets. Here, the optibelt SK S=C Plus guarantees that the procedure runs flawlessly.
Enormous tumbling mills are used for crushing raw materials. The drives move a holding capacity ranging from 40,000 to 160,000 litres.
In order to optimally comply with requirements, increase reliability and minimise the level of stretching, Optibelt V-belts with aramid-fibre tension cord are recommended.
After the materials are ground into raw meal and dried, these are burned to clinker in a rotary kiln at 1450°C.
A cooling process lowering the temperature to under 200°C takes place on the grate cooler in which the optibelt SUPER X-POWER M=S is used in part due to its excellent resistance to heat.

Success stories from our customers
The crusher is equipped with two sets of 20-8V 4250 RP belts. The belt tensioning and the maximum product lifetime of only six months are problematic issues. The necessary maintenance then shuts everything down and production is lost for two to three hours.
The switch to maintenance-free optibelt RED POWER 3 S=C Plus high performance belts means that production is also possible at high temperatures, generating annual cost savings of 5,114 US dollars.
90 kilometres east of the Swedish coast is where the cement manufacturer, Cementa AB, is located. Each year, over two million tonnes of cement are produced there. One of the largest and most modern stone crushers in the world is driven by wrapped V-belts from Optibelt.
In total, 64 low-maintenance and highly durable optibelt RED POWER 3 S=C Plus
8V 5230/13285 mm V-belts ensure that the drive of the stone crusher runs failure-free, even at maximum load.
