Mineral resource crushing is an extremely energy-intensive process, in which the raw material is ground from sizes up to 30 mm on average down to an extremely fine grading range. The specific properties of the material and the processing method determine the technology used: For grinding brittle materials such as limestone, brick, slag, lime, gypsum, and ore, as well as coal, vertical crushers are frequently used in the building materials industry and in coal dressing. Production facilities are getting bigger and bigger – and the higher the output, the more challenging it becomes to ensure trouble-free operation.
In crushing processes for limestone, brick, and coal, the bevel gears used in vertical crushers are not only subjected to tremendous impact loads and environmental loads, they must also exhibit a high degree of efficiency in order to reliably provide continuous power transmission. These stringent requirements require the type of precision gearbox component production that is guaranteed by Klingelnberg machines.
