Rely on our proven track record of SAG and AG Mill superiority. Since the early 1980s, we have been designing and manufacturing SemiAutogenous SAG and Autogenous AG Grinding Mills under the FullerTraylor brand. Semiautogenous grinding uses a minimal ball charge in the range of 615 while autogenous grinding uses ore only.

Autogenous Grinding Explained. Mill length was the primary variable investigated in an autogenous pilot mill circuit. The 5 diameter mill had both pebble ports and wide slotted grates. The plus mill product was crushed in a cone crusher and returned to the mill feed along with the minus plus 4 or 6 mesh fraction.
The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AGSAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
In this training module, we39ll cover the workings of a semiautogenous grinding mill, or SAG mill, that39s designed to be the first stage of a grinding circuit. Ore thats crushed in a primary
AN OVERVIEW OF SINGLE STAGE AUTOGENOUS AND SEMIAUTOGENOUS GRINDING MILLS Brian Putland Principal Metallurgist Comminution Orway Mineral Consultants brian IIR CRUSHING amp GRINDING CONFERENCE 2005 21 March 2005 Perth, WA ABSTRACT This paper discusses the challenges associated with the process design of single stage mills,
Autogenous mills, or AG mills, can accomplish the same size reduction work as two or three stages of crushing and screening. Often used in grinding at modern mineral processing plants, AG mills reduce the material directly to the desired final size or prepare it for the following grinding stages.
Every mining operation has a unique grinding process. Variable needs require versatile grinding equipment. Metso offers flexible autogenous AG mills, semiautogenous SAG mills, ball and pebble mills, as well as stirred mills to fit your needs. Grinding mills, spare and wear parts as well as maintenance and optimization services.
Xinhai efficient autogenous mill can achieve two and three stage crushing, part or all crushing of ball mill and rod mill, it is suitable for the coarse grinding after coarse crushing. Finally, in the actual production, Xinhai efficient autogenous mill improved production efficiency, controlled the cost in the operation, the customer is very
Autogenous Mill Types. There are basically three general types of autogenous grinding mills a. Primary autogenous mills which process directly the total discharge of primary crushers usually set at 6 to 10 open side setting.

An Autogenous Milling defined as used in this study, the term Autogenous milling means a process in which the size of the constituent pieces of a supply of rock is reduced in a tumbling mill
For the mining industry, our semiautogenous SAG grinding mill uses a minimal ball charge in the range of 615 percent. It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. Autogenous AG grinding mills involve no grinding media as the ore itself acts as the grinding media.
SAG is an acronym for SemiAutogenous Grinding. SAG mills are essentially autogenous mills, but utilize grinding balls to aid in grinding like in a ball mill. A SAG mill is generally used as a primary or first stage grinding solution. Attrition between grinding balls and ore particles causes grinding of finer particles.
AUTOGENOUS MILL FEED PREPARATION TO REDUCE UNIT ENERGY CONSUMPTION ABSTRACT The throughput and energy efficiency of an autogenous AG grinding mill are adversely affected by variability in rock size and rock competency. This applies to both fully autogenous and semiautogenous SAG grinding circuits.
