AG/SAG 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. Because of the range of mill sizes available, AG/SAG milling can often be accomplished with fewer lines than in a conventional rod mill/ball mill circuit. A diagram of types of AG/SAG

Hence from equation 7, to crush to the ball mill circuit feed size (x. 2) in open circuit requires specific energy equivalent to: f x f x 2. 1 W c ic. * 4 2 M x x. 1 (10) For closed circuit crushing the specific energy is: 1* 4 2. 1 2. 1. f x f x c ic W M x x (11) The difference between the two (eq 10 eq 11) has to be provided by the milling circuit with an allowance for the fact that
thyssenkrupp design closed circuit ball mill. Mar, deep learning based system identification of industrial ensp ensp the wet grinding circuit shown in fig consists of one rod mill in open loop one ball mill in a closed loop and a primary and secondary hydrocyclone for carrying out twostage separation raw ore from mines is fed to rod mill along with some amount of water the discharge slurry
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.% ore and 25% steel. The ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclones.
Supervisory expert control for ball mill grinding circuits . Apr 01 2008 #183; 1 Introduction Ball mill grinding circuits are important unit operations in the production of metals from ore The function of the grinding mill is to reduce the particle size of the ore such that the valuable mineral constituent is exposed and can be recovered in the subsequent flotation operation

Selection of Ball Mill is done as per product quality, fineness, nature of raw material, site conditions and specific requirements like:. Open circuit or closed circuit. Slide shoe bearing or Trunion Bearing. Wet or Dry Grinding. Central Drive or Girth Gear Pinion Drive.
circuit (ball mill 2) is the cyclone dilution water flow rate. Attempts to use this for density control were not successful. Because of the high magnetite concentration of the ore it was found that the actual density exceeded the required density, causing the density control loop to become unstable. If the operator did not intervene at this stage, the dilution water to cyclone would close
These 3 data bases cover crushers, HPGRs and AG/SAG/ball mill circuits. In particular the latter data base contains over 120 different operating plants and conditions. To illustrate the accuracy of the model, Figures 13 show measured specific energies from these data bases plotted against predicted ones for crushers, HPGRs and total circuits. How to Use the Model . Inputs to the model are

The circuit comprises a SAG mill, 12 m diameter by m length (belly inside liners, the effective grinding volume), two pebble crushers, and two ball mills in parallel closed with cyclones. The SAG mill is fitted with a 20 MW gearless drive motor with bidirectional rotational capacity. (Reversing direction evens out wear on liners with symmetrical profile and prolongs operating time.) The
The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum chunk size, product size as P80 and maximum and finally the type of circuit open/closed
Ball Mill Grinding Circuit The ball mill is in closed circuit with a sump and three cyclone classifiers. The ore and trim water are added to the ball mill and the outflow from the ball mill goes to a sump where additional water is added. The slurry from the ball mill is pumped out of a sump into two cyclone separators. The underflow from the cyclone is returned to the ball mill. Balls are
The designed ball milling circuit product is 80% passing 150 #181;m. Several large tonnage copper porphyry plants in Chile use an opencircuit SAG configuration where the pebble crusher product is directed to the ball mills (SABCB circuit). The original grinding circuit at Los Bronces is an example: the pebbles generated in the two SAG mills are crushed in a satellite pebble crushing plant, and then are
Ball Mill Operation. Ball mills ride on steel tires or supported on both ends by trunnions. Girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive. The prime movers are usually synchronized motors. During rotation, a portion of the charge is lifted along the inside perimeter.
22/12/2020#0183;#32;Very often in SAG circuits, the ballmill circuit is neglected. In many operations where economics dictate that throughput is worth more economically than the required sace in grind, the focus shifts to throughput so much that the available ball mill power is not used to the fullest extent. Even in those operations where a firm grind target is not adhered to and attainable throughput
