High efficiency autogenous mill can realize the second and third stage crushing and screening, and part or all crushing and grinding of rod mill or ball mill. Low power consumption, no dust pollution, less auxiliary equipment, easy production automation, and stable particle size.
In this case, Xinhai efficient autogenous mill solved these problems effectively. 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
Autogenous (AG) and semi autogenous (SAG) mills have been used for over 20 years for the coarse grinding of diverse ores (including gold, copper and iron ores). They offer advantages with regard to capital costs and operating expense compared to the secondary and tertiary crushers used in conventional size reduction systems.
AUTOGENOUS MILL FEED PREPARATION TO REDUCE UNIT ENERGY CONSUMPTION ABSTRACT The through put 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 semi autogenous (SAG) grinding circuits. In this paper we focus on an approach to
Intermediate Autogenous Grinding. Autogenous grinding tests were run in a 10 ft x 4 ft Rockcyl mill. The principle of prepared feed and media was utilized to determine how coarse a feed could be commercially fed to a rock mill.
Our mining mill has advantages of stable running, longer service lifespan, high grinding efficiency, reliable performance, convenient maintenance, and such. And our mining mill mainly falls into autogenous mill, semi autogenous mill and overflow mill. Technical description
SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. A SAG mill is usually a primary or first stage grinder.

17/03/20160183;32;Question what is an Autogenous mill? An autogenous (AG) mill is a grinding mill used in the minerals processing industry. It is shaped like a huge drum on its side and spins rapidly to carry ore to the top using centrifugal force. Gravity assist
Autogenous and semi autogenous mills are designed for grinding or primary crushed ore and are the most widely used in concentrators globally. Ball mills Ball mills are typically used for secondary and/or tertiary grinding to prepare the material for downstream concentration processes. Rod mills Rod mills are mainly used for primary grinding of crushed ore with a particle size range up to 50 mm
The highest throughput grinding circuits in the mining industry use autogenous grinding (AG) or semiautogenous grinding (SAG) mills. An AG mill is a tumbling mill that uses the ore itself as grinding media. The ore must contain sufficient competent pieces to act as grinding media and preferably be high specific gravity which, for example
An autogenous mill is a mission critical application found in the concentrator section of a mine. The mills primary task is to grind ore into a suitable size for the next step in the concentration process. There are many different types of mills; ball mills, rod mills, SAG (Semi Autogenous Grinding) and autogenous mills. In a ball mill
