Autogenous Mill SpringerLink
Autogenous mill is a type of grinding equipment that crushes material by mutual impact, grinding and peeling effect among material grains. In 1880, cylindrical One of the workhorses of the minerals industry is the autogenous grinding (AG) mill and its derivative the semi-autogenous THE MODELLING OF SCRUBBERS AND AG MILLS, WHEN

A Semi-autogenous (SAG) Mill utilizes steel balls in addition to the natural grinding media. T he addition of balls (typically 6 to 12 percent by mill volume o f 100 mm diameter or 125 mm diameterautogenous mills, many of the concepts are general and apply to any form of comminution. There is a continuum where one type of tumbling mill technology bleeds into the next: Pebble milling is a type of grinding that we won’t be covering; it is a type of secondary autogenous grinding similar to ball milling.Autogenous and Semi-autogenous Grinding Circuits

Autogenous Grinding Process SpringerLink
The process in which steel balls of 5–15% volume are added into the autogenous mill to enhance the autogenous grinding efficiency is called semiautogenous grinding. Based on practical experience, the size of steel ball should be 100–150 mm, for too small size will bring unsatisfactory result, and too big size will likely damage the lining Crusher product is typical feed to a ball mill using large diameter balls but not much grinding of 20-25 mm ore can be accomplished in an autogenous mill. Autogenous plus Pebble Mill are an excellent technique if the ore is uniformly hard and competent but it has not been popular because the porphry copper orebodies do not Autogenous Grinding & Semi Autogenous Grinding Circuits

Semi-autogenous grinding (SAG) mill liner design and development
SAG mill liner development draws primarily on practical experience from SAG milling operations supported by computer-based modeling of charge motion in SAG mills and on established good design practice. Liner design needs to respond to the process aspects of mill liner action that are critical to good SAG mill performance, i.e., the impact To date, CITIC HIC has cumulatively produced and delivered over 1,550 mineral grinding mills, with a total installed power of 3,900MW. Our large-size grinding mills hold a market share of 85% in the domestic mining market, and have been exported to more than 50 countries and regions. This means that we are a world's leading manufacturer andGrinding Mills Mineral Processing Equipment CITIC HIC

Steady-state and dynamic simulation of a grinding mill using
Autogenous Grinding (AG) is one the most important mineral processing assets in the comminution circuit, and its production performance directly impacts on the circuit throughput. Understanding the key parameters impacting the AG mill throughput is critical to reducing the operational variability and to improve throughput predictions.The special characteristics of the Autogenous mill are stated, and a suitable type of model for the mill is presented.
