“Macrograin range” refers to grains which are larger than 58 µ as per international standards (for comparison: the mesh width of a nylon stocking is approx. 250 µ). Customers often use individually adapted grain specifications in their processes in order to benefit from the maximum performance of the product for their process. Almost all mineral products can be mechanically screened.
We specialise in the ultrafine screening of mineral oxides, particularly Al2O3.
We will be happy to advise you on the further processing or disposal of potential by-products!
