The purpose of grinders in the mining industry is to reduce the feed material size in order to liberate the minerals from the barren rock. Ball mills are the most common grinding machine employed in the mining industry.
PDF (PC) Abstract: A rapid synthetic strategy through ball milling and recrystallization was successfully developed. Aluminophosphate molecular sieve with AWO topology was prepared by the precursor of two-dimensional (2D) layered aluminophosphate AlPO-IM. Simultaneously, metal-containing aluminophosphate molecular sieves with LAU topology …

This was then followed by separation of the product from the grinding media on a wire mesh. The mill product was then taken to a jones rifle splitter and homogenously separated into measured 100 g samples for sieve analysis. Using the -850 + 300 μm size class material, this procedure was repeated for all the grinding times considered.

The correct sieve tension keeps the material evenly stratified, ensuring good contact with the sieve while avoiding stock from laying on the sieve due to sagging of the sieve cloth. A properly tensioned sieve also flexes less, extending the life of the sieving material. For a purifier, polyester sieve material is the better option.
