One stage grading process with checking grading operation is the most widely used. The ore is directly fed into the grinding machine, and the optimum particle size for the ore is generally 6-20 mm. Particle checking classifier separates the ground material into qualified products and unqualified products, the unqualified materials are sent back to grinding mill.
The intuitively operated program NIAflow is a simulation software for a smooth process functioning in processing technology. NIAflow Basic, Aggregates and Mining provides its users a menu control which allows most beginners to design aggregate or mining plants almost immediately.
grinding, to single stage crushing and semi-autogenous grinding (SAG) and ball mill (SAB) circuits. This progression has, not necessarily, been accompanied by an improvement in the efficiency of power utilisation in achieving the target grind size, but has seen an improvement in the overall efficiency of mineral processing as

17.7.1 Crushing and grinding. Coal hardness is a key selection criterion for PCI coals. The cost of grinding and of mill productivity is related to the hardness of coal as measured by the Hardgrove Grindability Index (HGI). A high HGI is indicative of coals which are easier to grind, consume less power and have greater mill throughputs.
