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.
From a control point of view a ball mill grinding circuit represents an interconnected multivariable system with strong interactions among process variables.
Generalized Predictive Controller for Ball Mill Grinding Circuit in the Presence of Feed-grindability Variations Sivanandam VENKATESH1 . the bottom and is re-circulated into the ball mill for further grinding thus forming a closed circuit. The manipulated variables viz. feed
Describe the components of ball mill. Explain their understanding of ball mill operation. Explain the role of critical speed and power draw in design and process control. Recognize important considerations in ball mill selection. Reading amp; Lecture. In ball mills steel balls or hard pebbles to break particle based on impact and attrition.
Apr 25 2016 In a simple grinding circuit there will be a ball mill and a classifier. Some circuits especially in large mills have more units or two or three stages of grinding but whatever is said here will apply to the complicated circuits as well as the simple ones. The two types of ball mill in general use are the grate mill and the open-end mill. Most manufacturers make both kinds; the difference between them is that the grate mill
The ball mill has higher circulation load it generates only 30 -35 of actual fines you require to be called as product. If your product size needed is 100 passing 45 micron then the ball mill total discharge material will contain normally 30 of 45 micron. The rest is oversize which has to be ground again.
Dec 22 2020 Gold plant ball mill circuit operation. Very often in SAG circuits the ball-mill circuit is neglected. In many operations where economics dictate that throughput is worth more economically than the required sacrifice in grind the focus shifts to throughput so much that the available ball mill power is not used to the fullest extent.
According to different operation process ball grinding mill can be divided into continuous ball mill and batch ball mill. The feeding and discharging process of the continuous type ball mill is continuous which can be produced in open or closed circuit grinding applications such as cement ball mill ceramic ball mill.
In a ball mill circuit the output can be defined as the production rate of fines of the circuit. As for any output ball mill circuit output is a function of both its inputs and efficiencies. There are two inputs to a ball mill circuit the ore fed to the circuit and the power delivered by the grinding mill.
The mill used is a tube mill or ball mill.. In the open circuit mill the mill shell has a length of about 4 to 5 times of its diameter to obtain a prescribed fineness and the shell outer wall is sprayed with water to prevent the. and process control then extends into the field of hardware including equipment improvement and.
Apr 08 2021 A That is not something you can control like adjusting a ball mill. Most of the mines target a particle size and they control that. For example you set 150 microns and the plant will run around 150 microns. The decision is based on how much the costs are to
In a mining plant or processing mill they have a big grinding circuit for crushing raw material these are usually Ball or SAG mills. Inside these SagBall mill are big steel balls that grind ore via an impact process. In simple terms these hard metal steel balls get to the top of the rotating chamber and fall down crushing the ore being .
Opportunities for improved mill control based on the data from the on-line monitor are also discussed as well as the implications in terms of mill processing and maintenance performance. Recently a CSIRO monitor was also installed on a ROM ball mill and analysis of the vibration sensor data from this installation is currently underway.
straightforward as taking the CUF as total ball mill feed forward circuit mill feed can be obtained via a good survey and mass balance. Once the laboratory has completed the size distribution analysis of the ball mill feed CUF for the standard reverse circuit and ball mill discharge the CSE calculation is
The secondary milling circuit at Waterval UG2 Concentrator had undergone a circuit change with the commissioning of the IsaMill a horizontally stirred mill in parallel with the secondary ball mill. The operation treats the PGM bearing UG2 ore type and produces a final concentrate enriched with PGMs.
Jan 14 2009 Abstract A self‐optimizing high precision sampling fuzzy logic controller for keeping a ball mill circuit working stably and efficiently is proposed in this paper. The controller is based on fuzzy logic control strategy and a fuzzy interpolation algorithm is presented to improve the control precision.
The inference from this observation was that breakage of coarse rocks is limiting the circuit at the SAG mill. In consequence the ball mill appears starved of feed. Applying an in-house model of the power that can be drawn by an overflow ball mill showed that the installed ball mill is incapable of drawing the power available from the motor.
Jul 08 2016 The throughput capacity and efficiency of a SAG mill are affected by the significant recirculated load derived from over-size discharge product critical size pebble discharge that is screened out and may be stockpiled or requires secondary crushing prior to re-introduction to the SAG mill feed. Where the SAG millball mill circuit is the bottleneck in the processing plant the pebble circuit
Mar 20 2020 In this blog you can read there are multiple reasons for measuring density in the grinding circuit. In most sites a ball mill is used for grinding and a hydro cyclone for classification. The slurry needs to be continuously monitored and controlled. Density meters efficiently help operators to monitor and control the grinding circuit optimize it and prevent process failures.
These features distinguish stirred mills as fundamentally different from both ball mills and Tower Mills as demonstrated by Tables 1 and 2. Table 1 Typical Power Intensities of different Grinding Devices Table 1 Power Intensity of Different Grinding Devices Ball Mill is a 5.6m D x 6.4m L 2.6MW Tower Mill is a 2.5m D x 2.5m L 520KW

Feb 20 2019 On top of this many companies treat different parts of their mining operations as independent units. Its not uncommon for a large mine to have independent planners looking after blasting primary crusher throughput secondary and ball mill grinding as well as the concentration plant.
2.1 Pengertian Ball Mill Ball mill merupakan salah satu jenis mesin penggiling yang berbentuk silinder yang berfungsi dan digunakan untuk menggiling material keras menjadi material yang sangat halus. Mesin ini biasanya digunakan dalam proses pembuatan cat keramik semen kembang api batu bara pigmen feldspar dan serbuk material
