Durable Dry Type Mining Ball Mill 900x1800 Semi Autogenous Grinding Mill Semiautogenous mill introduction The autogenous grinding technology was divided into autogenous and semiautogenous according to add the steel ball whether or not in the mill Do not add steel ball is autogenous add a little ball
This semiautogenous mill also called semiautogenous grinding mill or SAG mill is mainly used to grind ores and other particulate matter in different fields like chemical industry mining field metallurgy industry building material sector and so on It is an autogenous mill in nature but it employs grinding balls to assist in its grinding just like in a ball mill
Semiautogenous grinding uses a minimal ball charge in the range of 615 while autogenous grinding uses ore only SAG and AG Mills operate by lifting oregrinding media and dropping it on the operating bed of the mill charge
The designs of autogenous and semiautogenous SAG grindings mills are described followed by the description of their methods of operation in grinding circuits involving crushers and ball mills Methods of estimating SAG mill volumes mill charges feed size and power consumptions and optimum speeds of rotation during operation are described
SemiAutogenous Mill Note the size of the mill Why does the diameter need to be so big 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 AMIT 135 Lesson 6 Grinding Circuit
the mill is used primarily to lift the load medium and charge Additional power is required to keep the mill rotating 813 Power drawn by ball semiautogenous and autogenous mills A simplified picture of the mill load is shown in Figure 83 Ad this can be used to establish the essential features of a model for mill
Oct 12 2017· Today we will learn about difference between sag mill vs ball mill A mill is a machine by which solid or hard materials are broken into smaller pieces by means of grinding crushing or cutting This commutation is an essential part of many processes Various kinds of mills are there with which different material processing takes place
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
Jul 30 2012· Autogenous AG and SemiAutogenous SAG milling has seen increased use in recent years especially in large mineral processing operations These mills typically have a large diameter relative to their length typically in the ratio or 2 or 25 to 1

Semiautogenous mills are more common The AG Mill or SAG grinds primary crusher product and prepares it for final grinding in a ball mill Its product is usually passed over a large vibrating screen to separate oversize ''pebbles'' from correctsize particles The correctsize material is sent forward to a ball mill for final grinding
This semiautogenous mill also called semiautogenous grinding mill or SAG mill is mainly used to grind ores and other particulate matter in different fields like chemical industry mining field metallurgy industry building material sector and so on It is an autogenous mill in nature but it employs grinding balls to assist in its
ball wear These are known as semiautogenous grinding SAG mills In the mining industry all of these types of mills are in use The operation of AGSAG mills therefore involves the use of cheaper grinding media as a replacement for expensive steel balls and rods which greatly affect the wear on liners
machines to the current multistage semiautogenous SAG and ball mill circuits This progression however has not always been accompanied by an improvement in the efficiency of power usage in achieving the target grind size According to the Coalition for EcoEfficient Comminution CEEC
