Flexco is an internationally leading specialist for mechanical conveyor belt fastener systems, belt cleaners, belt trainers, impact beds and drum coatings. An application engineer at the company explains the situation: “Our customer, who operated a conveyor system for cement clinker, was constantly having problems with belt misalignment.” This was not only causing major losses of clinker, it was leading to premature wear. And that endangered the operation of the belt and the efficiency of the entire system. When material accumulates in the rollers of such systems, they jam, creating tension in the belt and at the fastening points. If the belt tears, the system comes to a stop. Production ceases until the conveyor is up and running again. That costs money, and the safety of the system cannot be guaranteed.
The cement manufacturer’s service technicians had to perform frequent maintenance and repair the belts by means of vulcanization – usually after only four to six weeks. In vulcanization the ends of the belts first have to be prepared and afterwards the connection has to harden – a process that takes four to six hours. During this whole time the system cannot run. Another problem was that when the belt wandered it pressed against the supporting structure, which acted like a saw. Owing to this wear, the operator had to replace the belt every 14 to 16 months – an expensive matter.
The cement manufacturer tried out a number of belt trainers from different providers in order to reduce its costs. But none of the systems was able to correct the belt misalignment. Finally the company turned to Flexco. “We took a close look at the application and recommended our PTEZ series,” reports Flexco’s application engineer.
