monitor the primary crusher product and feed to the SAG mill. Such . systems can also be used to monitor the effect of crusher gap aperture . plus mantle and concave wear.
The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 8:1. Feed: ROM up to 1.5 m; Product: -300mm (for transport) to -200mm (for SAG mill) Feed Rate: 160 to 13,000 tph
Ball mill： Ball mills are the most widely used one. Rod mill： The rod mill has the highest efficiency when the feed size is <30mm and the discharge size is about 3mm with uniform particle size and light overcrushing phenomenon. SAG mill: When the weight of the SAG mill is more than 75%, the output is high and the energy consumption is low ...

During the primary crushing operation, boulder size feeds from 20 to 100 in. are reduced to secondary crusher sizes of 1 to 20 in. or mill feed size of .5 to 3 in. Many different types of crushers exist with varying designs and crusher processes. The proper choice is dependent on several factors, including the hardness of the material to be ...
Since there are not that many small SAG mill operations of under 2000 TPD, and most sub-2000 TPD mills are built with rod mills and/or ball mills only; the upstream crusher plant needs to have sufficient crushing power to provide a P80 to grinding of typically <1.5″ (40 mm) and often as finely crushed as <3/8″ (9 mm).
Single stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach. When future tonnage is to be increased, the SAG Mill can feed downstream ball milling to boost capacity. Fuller-Traylor SAG/AG …

SAG Mill Circuit Example — Gold Processing SAG mill circuit example for gold processing [image: (135-6-3)] AG/SAG Mill. AG/SAG mills are normally used to grind run-off-mine ore or primary crusher product. Wet grinding in an AG/SAG mill is accomplished in a slurry of 50 to 80 percent solids. 2D and 3D simulations of particles in a SAG Mill
Having been in a few process plants with SAG mills & they are inefficient- as low as 1% - since power costs are becoming a big issue there is lots of research being done ( try googling under SAG Mill efficiency) -technically I wouldn't consider them a 'crusher'- they are grinding mills and some mill people might take offence- note that SAG mills are high …
P80 is the SAG hydrocyclone overflow 80% passing size, µm F80 is the milling circuit feed 80% passing size, µm, fSAG is a calibration parameter for pebble crushing and/or fine feed (typically 1.0 for 80% passing six inch mill feed and when no pebble crusher is present). WiBM is the Bond ball mill work index, unitless
Crushing ratio The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials …
The grinding circuit consists of an SABC circuit, with a SAG mill followed by a ball mill and a pebble crusher to crush the SAG mill trommel oversize material. Primary crushed ore is reclaimed from the stockpile via two apron feeders which can operate individually or in parallel to provide the 385 t/h. The mill feed is conveyed to the primary
SAG mill, AG mill, milling, HPGR, work index, pilot plant INTRODUCTION The resistance of ore samples to breakage (or hardness) is measured ... situations, crushers are more often designed from a crusher index only, which covers a very small reduction range, or using suppliers' charts,
According to the different grinding media and grinding materials, the mill can be divided into: ball mill, rod mill, AG mill, SAG mill, vertical mill and so on.When working, the motor rotates the cylinder through the transmission gear, sprocket or belt, and the centrifugal force generated will bring the grinding media and materials to a certain height and then fall, which will produce …
Morrell Mi (SMC) SAG & ball mill Model. This is a SAG or AG mill plus ball mill model that estimates the specific energy consumption (E SAG) using the equations of Morrell (2004). Testwork Required. The SMC™ test, stored in the "DWT" testwork table (SMC is a Drop Weight Test). Bond ball mill work index.
the SAG mill and pebble crushers provides an opportunity to manipulate the feed rate to the pebble crushers independently of the SAG mill pebble production rate. This flexibility, along with excess pebble crushing capacity, enables the pebble crusher specific energy to be maximised the majority of the time. Pebble

SAG mill liners are different from ball mill liners. the diameter and input size of SAG mill is larger than ball mill. And the grinding media are more less than ball mill. The mining materials need to be a part of grinding media. That means the SAG mill should be hard enough to resist the impact from the mining rocks and not be yield or bend.
