Mining Industry: What is the difference of ball mill, attrition .Most mills used in mining rely on impact to breakdown rock to a suitable size for downstream processing. The impact can be rock on rock such as in an Autogenous Grinding (AG) mill, rock and a small ball charge (~10%), used in Semi Autogenous Grinding (SAG) mills, balls of various sizes in Ball Mills and less commonly.difference between sag mill and ball mill,Difference Between Sag Mill vs Ball Mill - mech4studyOct 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.
Sep 10, 2010 . equipment available and then evaluating what the expected throughput will be using the largest SAG and ball mills available. The task therefore shifts from SAG mill design, to how many tonnes will the given SAG mill grind in one hour. When the difference between design methods used by different.
Jul 3, 2017 . The voids (or interstitial space) within a rod load are approximately half those in a ball mill grinding load. Rods in place weigh approximately 400 pounds per cu. ft. and balls in place approximately 300 pounds per cu. ft.. Thus, quantitatively, less material can progress through the voids in the rod mill.
The feed size for these mills is limited to the maximum size that can be practically conveyed and introduced into the large mill feed chutes. And the product of the large AG/SAG grinding is either a finished size ready of processing, or an immediate size for further grinding in a ball mill, pebble mill, or a VERTIMILL® or a stirred.
However, the ball load in these mills is significantly higher than that for. SAG mills SAG mills are normally operated with ball loads ranges from. 5 – 18 % volumetric filling while RoM ball mills are operated with ball loads ranging between 25 and 40% volumetric filling. The main difference between the two is that the ratio of.
What's the Difference between SAG Mills (Semi-Autogenous) and AG mills (Autogenous)?. Autogenous mills use the ore itself is the grinding media. Semi-autogenous grinding uses a minimal ball charge in the range of 6-15%, and is primarily used in the gold, copper and platinum industries but also in lead, zinc, silver, and.
With a higher density mill charge. SAG mills have a higher installed power density for a given plant footprint relative to AC mills. With the combination of finer grind and a lower installed power density (based on the lower density of the mill charge), a typical AG mill.
Jul 3, 2017 . The voids (or interstitial space) within a rod load are approximately half those in a ball mill grinding load. Rods in place weigh approximately 400 pounds per cu. ft. and balls in place approximately 300 pounds per cu. ft.. Thus, quantitatively, less material can progress through the voids in the rod mill.
Semi-Autogenous (SAG) Mills: SAG mill is similar to AG mills, but utilizes grinding balls to aid grinding just like ball mills. It uses a ball charge of approx. 6 - 15%. SAG mills are characterized by their large diameter and short length as compared to ball mills. SAG mills are primarily used in the gold, copper and platinum.

SAG Mill - Semi-Autogenous Grinding Mill. A semi-autogenous grinding mill, or Sag mill, is responsible for grinding materials from large chunks into small, usable pieces for processing. The Sag mill is usually part of the primary stage in the grinding process. Pieces of raw or fairly reduced materials are ground into smaller.

ball mills. The rankings obtained from the tests were identical with those from the full BMA test, although the difference between the different grades was not as marked. . Ball mill balls experience a greater number of impacts, but at lower magnitude than SAG mill balls, due to the smaller ball size, and smaller mill diameter.
Nov 11, 2015 . Partitioning the Total Energy Between SAG and Ball Mills. The Bond-based method applied by Barratt involves deducting a SAG mill specific energy consumption, ESAG, from the overall circuit specific energy consumption, Etotal, with the difference being the ball mill specific energy consumption, Ebm. One.
(m)*3.88 length(m)) following two parallel ball mills (5dia.(m)*7lenght(m)). After SAG mill, a trommel screen produces two over and under size materials which the oversize part . variation is between 1.2– 3.7% which is lower than mill ball filling percentage, according to the designed .. differences between metallic balls and.
building the batch mill that facilitates changeable lifters and is equipped with a state-of-the art load cell for force . well. At 80% critical speed, the power draw of the different lifters decreased compared with .. SAB is SAG-ball; ABC is AG-ball with pebble crusher; SABC is SAG-ball with pebble crusher;. SS is single stage.
The combination of HPGR and stirred mill in a single flowsheet without tumbling mills has been demonstrated to be technically feasible. This research focused on the energy and cost comparisons of the existing AG/SAG ball mill circuits with two proposed comminution circuits, including an HPGR - ball mill circuit and a novel.
Jul 31, 2017 . Abstract: The impact behavior between the charge and lifter has significant effect to address the mill . for the ball mills, while the power draw determined by DEM simulation show a good approximation ... and the major difference can be explained by the fact that Bond formula does not consider the effect.
May 1, 2011 . Before the Esperanza order, FL's largest SAG mill measured 38' and its ball mills, 26'. To the average person, the difference between a 38' and a 40' SAG mill is a mere two feet. However, diameter growth has exponential consequences, and the two extra feet of mill capacity required some serious.
