Milling is one of the major toll services for minerals offered by African Pegmatite, alongside drying and granulation. Processing minerals requires specialised machinery that's suited for the type of mineral being milled. There are quite a few machines for mineral milling and each has a unique specialisation.
Some of our most frequently-used machines include ball mills, hammer mills, Raymond mills, cone crushers, roller crushers, attritor mills, and jaw crushers. Ball Mills This modernized grinder is filled with chrome or forged ballsl, depending on the mineral being milled.
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
