Primary Secondary AG Autogenous Grinding

2018. 4. 20.  Automation of primary mills using a combination of mill power and mill sound is recommended to constantly watch the mill operation and adjust the feed rate to compensate for the variables in the mill feed. Secondary autogenous mill feed is normally rod mill product or an equivalent size from a roll crusher or a primary rock mill. Media, sized and removed from the ore stream ahead of the mill, is selected to have the proper size and weight to grind the mill feed. In secondary rock milling

Mill (grinding) - Wikipedia

In materials processing a grinder is a machine for producing fine particle size reduction through attrition and compressive forces at the grain size level. See also crusher for mechanisms producing larger particles. In general, grinding processes require a relatively large amount of energy; for this reason, an experimental method to measure the energy used locally during milling with different machines was recently proposed. A typical type of fine grinder is the ball mill. A slightly inclined or horizontal rot
