One sag mill 975 diam388 lengthm following two parallel ball mills 5diam7lenghtm the aim of this research work was to investigate on the ball filling estimation of miduk semiautogenous sag mill via an utilized method miduk sag mill circuit is shown in figure 1 figure 1 diagram of miduk copper complex
Jan 01 2016 based on these test results a 67 m diameter 21 m length sag mill and a 33 m 61 m ball mill were installed for commercial operation in closed circuit with a hydrocyclone the sag mill had a 68 ball charge and the power consumption was 8 kwht which agreed well with the expected value 96 problems 91
If the sag and ball mills feed separate pump systems this is not an issue if the two stages feed the same pump system the sag mill usually drives the discharge arrangement this is because the sag mill is usually of larger diameter and may have a requirement for screening of pebbles to protect the mill discharge pumps and cyclones and to
2 ag mill a recycle crusher competent ore relatively homogenous the recycle crusher is used to balance the rate of impact breakage within the circuit 3 sag mill 8 15 ball charge variable competency ore 4 high ball charge sag mill 15 to 25 ball charge incompetent ore 5 low ball charge sag mill high mill speed

The ball mill accepts the sag or ag mill product ball mills give a controlled final grind and produce flotation feed of a uniform size ball mills tumble iron or steel balls with the ore the balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds the feed to ball mills dry basis is typically 75 vol
The ability to simulate the bond work index test also allows examination of truncated ball mill feed size distributions on the work index for grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill see figure 310 a question arises as to whether this practice will alter the ball mill work index bw i of the material

Mill type overview three types of mill design are common the overflow discharge mill is best suited for fine grinding to 75 106 microns the diaphram or grate discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 250 microns the centerperiphery discharge mill has feed reporting from both ends and the product discharges
The discharge from the sag mill is screened by a trommel screen mounted at the discharge end of the mill the oversize material is recycled to the sag mill feed via conveyors and the undersize material is combined in the cyclone feed sump with the ball mill discharge and feed to the ball mill

Jun 01 2005 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 wouldnt consider them a crusher they are grinding mills and some mill people might take offence note that sag mills are high compared to lengththis is so the
Main technical parameters ball mill sag main technical parameters ball mill sag 1994 the key parameters of the test are the main grinding circuit at of these samples was screened to give sag product p80 and ball mill product the sag mill and ball mill are sag mill mills which have equal technical competence with oyu
