Ball Mill an overview ScienceDirect Topics

William G. Davenport, in Extractive Metallurgy of Copper (Fifth Edition), 2011. 3.5.2.2 Ball Mills. 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 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The

Copper mining Secured recovery Magotteaux

The grinding media cost was reduced by the equivalent of 200,000 USD/year by switching to a lower cost Duromax ® cast grinding ball. The customer indicated that should the plant suffer a loss in copper recovery they would revert to the initial alloy.

Investigation of the laboratory conditions effects on the

Industrial data were obtained from a copper molybdenum mineral processing plant in Turkey. The desired mineral was chalcopyrite with a silicate tailing and a density of 2.85 g/cm3. The plant had a grinding circuit consisting of a primary ball mill (PBM) in an open circuit and a secondary ball mill (SBM) in a closed circuit with hydrocyclones

Analysis of the Effects of Grind Size on Production of

Samples from the ball mill feed were collected for the investigations at the mine laboratory. Laboratory flotation tests were carried out at various levels of grind; namely 15.33%, 19.52%, 28.16%, 39.47% and 51.51% passing 75microns sieve aperture, For each test, timed flotation concentrates were collected at intervals of 0.5, 1, 1.5 and 4 minutes. Natural pH level was maintained for all the

Grinding in Ball Mills: Modeling and Process Control

• characteristics of the grinding media (mass, density, ball size distribution); • speed of rotation of the mill; • slurry density in case of wet grinding operation. Quantitative estimations of these parameters can be found in [4, 5, 23]. An important characteristic of an industrial ball mill is its production capacity

Optimization of mill performance by using

to the volumetric mill filling which influences grinding media wear rates, throughput, power draw, and product grind size from the circuit. Each of these performance parameters peaks at different filling values. In order to contin-uously optimize mill operation, it is vital to obtain regular measurements of the ball load and pulp position. The current way to measure the charge filling degree

Modeling of the planetary ball-milling process: The case

01/08/2016· Among high-energy ball mills, the planetary is a mechanically simple and versatile device for efficient grinding. It is usually made of two or more jars, rotating at an angular velocity ω around their axis (see Fig. 1), installed on a disk rotating at angular velocity Ω.Grinding occurs by impact among the milling media (balls and jars), driven by centrifugal and Coriolis forces, with

CS Mining makes the grade with the Derrick Stack Sizer

The grinding circuit consisted of two parallel ball mills in closed circuit with hydrocyclones. Each milling circuit was able to process at a rate of 35 t/h at a P80 of 120 microns. Solution To improve the grind size fed to flotation, the cyclones on number 2 ball mill were replaced with two 5-deck Stack Sizers® and 100 micron panels. The ball mill closed with the screens was able to process

Comparison of One Stage and Two Stage Classification —

CBI is processing complex copper/zinc sulphide ores. The Cayeli concentrator was commissioned in 1994, with a design capacity of 600 000 tonnes/year. The grinding circuit was a classical rod mill/ball mill combination. The rod mill was converted to a primary ball mill in May 1997. The reasons for conversion were to use mill power more

Load Behavior Prediction in a Tumbling Mill Scientific.Net

mportance of the SAG (Semi Autogenous Grinding) mills for the mineral complexes persuades many researchers to study the behavior of these huge equipments. Laboratory mills and the DEM (Discrete element method) software are the prevalent and reliable methods of modeling the mill behaviors. The former is very costly and the latter not only takes the much time but also needs the very advanced
