Thus a semiautogenous and autogenous grinding mill is preferred for grinding in mining industry on account of its extremely high availability rate high throughput and low energy consumption however grinding in such mills bees a plex process as the feed rate and mineralogical properties of the ore dictate the mill properties

grinding autogenous semiautogenous-XinHai Mineral

Semiautogenous grinding uses a minimal ball charge in the range of 615% while autogenous grinding uses ore only. SAG and AG Mills operate by lifting ore/grinding media and dropping it on the operating bed of the mill charge. High impacts from lifting ore and media promote impact breakage which is the primary mechanism for size reduction in the mill.

Autogenous and Semiautogenous Grinding Practices

In the past 10 years, there has been a strong trend toward using autogenous or semiautogenous grinding in mills throughout the world. Autogenous grinding is favored when the ore is quite competent and a fine grind is needed. Semiautogenous grinding is applied when fine crushing could cause severe problems or when ore varies in hardness or competency.

Testing for autogenous and semiautogenous
