Market Requirements as a Driver of Innovation
In cement production, large quantities of bulk material are transported in all areas of materials handling and storage technology. This is why we are dedicating this issue of the Kalenborn Report to focusing on the linings used in cement works. Read how Kalenborn develops wear protection systems for mill lining and sifter systems in the form of the KALCRET hard compound and the KALMETALL-W hard overlay welded plates and in so doing meets customer demands for longer service lives.
Good Protection is Half The Battle Won
The south of France not only boasts olive plantations and fields of lavender. The region is also home to cement works which present Kalenborn with new challenges. In order to optimise the process of grinding cement, a European cement manufacturer decided to procure a new vertical roller mill. however, as the facility only produces special cement cont-aining a high fraction of granulated slag, the mill is subjected to heavy loading. This places great demands on the wear protection and on extending the lifespan of the facility.
KALCRET – Wear Protection That Can be Trowelled, Cast or Sprayed on
Linings with KALCRET protect plant components and pipes. There are already many successful applications throughout the raw materials industry, for example in mining, in power plants, in the steel and cement industries, and in waste incineration plants. In cement works, the pipes in clinker dust pipelines are lined with KALCRET and in cement grinding KALCRET is used to protect the sifter lining.
A bucket-wheel excavator is responsible for unloading iron ore pellets from the ship and at the same time transports them by conveyor belt to the steelworks. From time to time in the past, the pellets got caught in the wear protection on the bucket-wheel structure. The stray pellets caused additional weight on the bucket wheel and thus disrupted the smooth running of the machine. Here, a solution was needed.
Protect What Keeps us Warm
Kalenborn’s wear protection solutions are also needed in northern regions. At the plant of Estonia’s leading producer of shale oil, oil shale is separated to produce shale oil and shale gas. The plant grinds wet oil shale around the clock and guides the rock via conveyor belts into a flash dryer where it predries. The issue of wear protection in the flash dryer had hitherto largely been ignored. As a result, the plant components were sensitive and only had short service lives. The company asked Kalenborn to develop specific wear protection solutions for the plant parts with a wide range of different.
