In a autogenous mill the ore is fed directly into the mill from either the primary crusher or the mine itself. The size of the rock will be between four and eight inches. It will be this type of mill that will use a stock pile instead of a bin as fine ore storage. The feed is large enough that moisture and freezing won't bother it.

the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. 8.1.3 Power drawn by ball, semi-autogenous and autogenous mills A simplified picture of the mill load is shown in Figure 8.3 Ad this can be used to establish the essential features of a model for mill power.
Intermediate autogenous mills (or intermediate pebble mills) which process a fine crushed product (minus 5/8″ to minus 1″) obtained from an intermediate crushing plant. The grinding media in these mills are rock pebbles of suitable size (3″ to 6″) screened out of the intermediate crushing circuit.
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
MQY Wet Overflow Ball Mill-Jiangsu Baisheng Machinery Ltd.-Introduction Baisheng MQY wet overflow ball mill is a cylinder with small diameter and big length which is revolved by transmitting machinery. Materials are put in cylinder through the feed opening and then thoroughly grinded. The falling course of iron balls and ores can produce huge falling impact and autogenous …
· Gyratory Crusher. Gyratory crushers are similar to cone crushers; they are frequently used in large-throughput primary crushing roles. Typically, they have larger capacities (up to 8000 tph) compared to jaw crushers (up to 1500 tph). Gyratory operate at a slower speed than cone crushers, typically in the range 85 to 105 rpm.
An autogenous grinding mill may receive a coarse run of mine rock feed and discharge it as a finished ground sand or slime product. In order to efliciently break down the rock the mill must provide both impact and attrition forces. ... Crusher mill US2941731A (en) : Precision grinder US2188230A (en) : Crusher US1955960A (en ...

The uptake of Semi Autogenous Grinding (SAG) eliminated the need for crushing plants other than a primary crusher. The use of pebble milling has seen resurgence in the use of cone crushers ...
The ball milling process is prepared by rod mill, sag mill (autogenous / semi-autogenous grinding mill), jaw crusher, cone crusher, and other single or multistage crushing and screening. 【 Ball Mill Manufacturer 】 With more than 35 years of experience in grinding balls mill technology, JXSC design and produce heavy-duty scientific ball mill ...
Primary autogenous mill feed is either primary crusher discharge or run of mine ore, containing material on each size of the screen analysis below the largest piece in the feed. It is subject to the large variations in size analysis normally found in primary crusher products or run of mine ore.

For autogenous mill or crusher design, the numbers are then used in the appropriate computer models, developed by JKTech, and part of the JKSimMet program. WHEN SHOULD I DO A DROP WEIGHT TEST? • For autogenous mill sizing. The DWT is used with JKTech autogenous mill modelling to size the autogenous mill(s) when designing a grinding circuit.
Autogenous mill, pebbles, ore sorting INTRODUCTION A well known natural phenomenon in autogenous (AG) mills is the build-up of pebbles. These pebbles are typically called "critical size material" and occupy a large volume of the mill and thus …
The smaller the crush size, the more rapidly the pebble load will be reduced, so we recommend using a heavy, robust crusher, such as the ® TC series, to achieve higher throughput rates in the milling circuit. * McIvor, R. & Greenwood, B. (1996). Pebble Use and Treatment at Cleveland-Cliffs' Autogenous Mill Operations.
The TITAN Scrubber design is based on the Mill design for high-Attrition power on 30% Charge volume at 60% critical speed resulting in high rate power transfer (Wi) needing only 45-65 second retention time (instead of the conventional 90sec). Attrition power transfer similar to AG Mills (E-Model) work principle.

Autogenous mills are fed run-of-mine ore or primary crusher product that is <25 cm (10″). Inside the mill, large pieces break into smaller pieces a few inches in size. These natural pebbles act as the grinding media the autogenous mill. The main modes of breakage are thought to be impact breakage and abrasion.
SAG Mill Liners. SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. SAG mill is usually used to grind large pieces into small pieces, especially for the pre-processing of grinding circuits, thus also known as primary stage grinding machine.
supported grinding mills up to the largest sizes. SAG/ball mill circuit incorporating pebble crushers and a POLYCOM® high-pressure grinding roll. SAG and ball mill for gold ore grinding. One of three SAG mills with 9.75 m diameter and 2 x 4000 kW drive power. These mills operate in conjunction with ball mills for iron ore grinding in Iran.
Autogenous grinding (AG) and semi-autogenous grinding (SAG) mills use the material to be ground as the grinding media. Autogenous grinding mills use larger rocks to impact and break smaller rocks as the mill rotates. Semi-autogenous mills are basically the same autogenous mills, but with the addition of balls, similar to those in ball mills.
Semi autogenous mill is mainly used in non-ferrous metals, mining, metallurgy, cement and other industries. The semi autogenous mill has the advantages of large crushing ratio, high efficiency, low energy consumption, uniform product size, and suitable for crushing and fine crushing of various ores and rocks
The OreMax is available as a fully-autogenous, semi-autogenous or anvil type crusher. The anvil type units are designated as OreMax - ST/AR machines. The OreMax Pre-mill units are designed for extra-fine crushing and grinding.
The primary differences between these mills are in the ratio of diameter to the length of the cylinder and the type of grinding media employed. Grinding media can be steel rods, steel balls, hard pebbles or the ore itself. Autogenous and Semi-Autogenous Mills Autogenous (AG) and Semi-Autogenous (SAG) milling has seen increased use in recent years,
