The cost of replacement of the metal worn from the ing surfaces of the balls and liners of a mill often represents a considerable fraction of the cost of operation of the plant and so is of some real economical importance. In spite of this importance, however, the amount of information in availe on this subject is amazingly small and, unfortunately, is insufficient to form the basis of

Dec 08, 2009· Re: how to estimate the wear rate for Ball mill. Most practical way to by measuring empty height and calculating the % volumetric filling of grinding media.Alternative way to make track of mill main drive kW consumption reduction and add makeup charge according to the extent of fall in power consumption.
An online calculator lets you calculate Top Ball Size of Grinding Media for your mill. Use this Equation & Method to properly grind your ore.
plant ball mill’s grinding efficiency (Fig. 1). The functional performance parameters “mill grinding rate through the size of interest,” and “cumulative mill grinding rates” from both plant and small-scale tests are applied to this task. A plant media sizing methodology, and industrial case studies, are
In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in case”. Well, this safety factor can cost you much in recovery and/or mill liner wear and

Ball Mill Grinding Media Wear Rate. Again this signal fits correctly with a filling degree estimation based on ball additions and a ball wear rate of around 40 gkWh Again this demonstrates that the Sensomag is able to finely and continuously follow the evolutions additions of grinding media level inside a running ball mill.
Jul 01, 2016· 2.3. Wear of grinding media. One of the major problems regarding the use of ball mills is to balance the size distribution of grinding media into the mill, which is determined by the speed of consumption and rate of replacement,as the wear of the grinding balls requires
Mar 15, 2015· Fig. 2 shows the self-wear curves of different grinding media in water versus time. The lines marked with s (A1 and B1) are the results in rapid pot mill, and those marked with circles (A2 and B2) are in vertical stirred mill for media A and B, only the wear-rate curve of media C in rapid pot mill is examined.
A common used equation to compute the wear rate is (Archard,1953). V i =k i F s. where F is the normal load, s the sliding distance, V i the wear volume and k i the specific wear rate coefficient. Index i identifies the surface considered. The k-value is given in m 3 /Nm or m 2 /N, sometimes in mm 3 /Nm. From design view the wear displacement h

- Ball top size (bond formula): calculation of the top size grinding media (balls or cylpebs):-Modification of the Ball Charge: This calculator analyses the granulometry of the material inside the mill and proposes a modification of the ball charge in order to improve the mill efficiency:
media shape and mill power. The objective of this dissertation was to investigate how media shape affects grinding. Ball size distribution inside an industrial mill was analysed in terms of shapes and sizes. Load behaviour, mill power and breakage as affected by media shapes were studied in a pilot oratory mill. An inductive proximity probe
Aug 30, 2019· 1 Calculation of ball mill capacity. The production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of the ball mill, in addition to the nature of the material (grain size, hardness, density, temperature and humidity), the degree of

Ball Mill Size as a Replacement. Grinding media wears and reduces in size at a rate dependent on the surface hardness, density and composition of the ore. Ball wear is directly proportional to surface area per unit mass and thus inversely proportional to ball diameter. Other factors include: Speed of mill rotation; Mill diameter; Mineral density;
