While the overall aim is to reduce particles to a desired size, the grinding process can in general be conducted in two different ways – dry or wet.
In the mining industry, dry grinding plants are primarily used when the downstream preparation process requires dry material, or in order to save valuable water resources. Grinding equipment from thyssenkrupp Mining Technologies is successfully in operation all around the world, grinding and drying gold ore, iron ore, iron ore concentrate, limestone, cement clinker, lime and coal as well as other mineral raw materials throughput capacities.
Wet grinding in contrast involves the use of liquids/water to process the material. The feed material is dispersed in the liquid. The resulting slurry is then circulated in the mill where it is ground with ?? solid grinding media. Wet grinding is commonly used when the target size of the material is very small. However, wet grinding is one of the most energy-intensive production stages and therefore has a substantial energy-saving potential which is realized by our thyssenkrupp Mining Technologies mills.
