The use of small grinding media 5 12 mm called Millpebs in regrind mills proved that fi ner grinding can be achieved at lower energy consumption In ball mills energy savings vary from 10 per cent to 40 per cent compared to 25 mm media
Energy Saving Ball Mill Product Introduction A high efficiency and energy saving ball mill with rolling bearing Capacity Up to 160th Product Improvement Cylindrical energy saving grid ball mill is lined grooved ring plate which increases th
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 ative way to make track of mill main drive kW consumption reduction and add makeup charge according to the extent of fall in power consumption
The ball mill grind various ores and other materials either wet or dry There are two kinds of ball mill grate type and overfall type due to different ways of discharging material There are many types of grinding media suitable for use in a ball mill including ceramic balls
The disadvantages of ball mills include their considerable metal consumption and deterioration grinding media as well as a lot of noise Most of the energy useless lost during ball mill operation leading to low it efficiency But even a significant specific energy consumption for grinding material compensates beneficial effect by using mill
Mar 30 2016· The media consumption of processing the raw ore dropped from 08 kgt to 03 kgt equivalent to a 60 reduction With an annual output of 800000 tons of iron concentrate the savings in grinding media alone can amount to RMB 24 million Yuan per year 98 availability

The consumption of the grinding media represents an expressive part of the grinding operational costs it may reach up to 40 of the costs in a mineral processing unit and wear constitutes around 60 of the cost relative to ball mills
A cement mill or finish mill in North American usage is the equipment used to grind the hard nodular clinker from the cement kiln into the fine grey powder that is cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills

Ball Mill is a 56m D x 64m L 26MW Tower Mill is a 25m D x 25m L 520KW Table 2 Mill Comparison of Media Size Power Intensity number of grinding media The ability to use smaller media is probably the dominant impact on grinding efficiency It dramatically increases the grinding surface area and the number of grinding "events"
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 laboratory mill An inductive proximity probe

Grinding media consumption is one of the major operating costs in mineral processing industry it was found that the consumption of media in ball mills during grinding operation can be up to 50 of
grinding media consumption formula for ball mill ball mill grinding ball consumption grinding media steel balls on power requirements and energy consumption of a ball mill With constant mass of the steel balls 20 30 and 40 kg the agitator shaft speed was increased from 10 to of the maximum speed which corresponds to a speed of 50 rpm
than 50 compared with traditional ball mills and the SMD energy savings are far greater than 50 of ball mill energy in finegrinds Media Savings Media consumption is directly related with energy efficiency At a concentrator in Mexico they experienced reduced media consumption from a previous average of 821 gt to 429 gt or a 48
Ball mill rotating speed when grinding ball adding rate remains constant the useful power of ball mill varies with the rotating speed therefore production efficiency will also be influenced Ball mill rotating speed need to be adjusted according to different types of ores grinding media consumption accounts for 6590 of the total
A big majority of people is still using the old Bond equations without asking themselves do 950 gt or 1100 gt of steel consumption in the ball mills make sense When we apply our experience from the last 20 years we see right away that steel consumption in the range of 1000 gt in a ball mill is not correct and that is a fact
The ball mill can grind various ores and other materials either wet or dry There are two kinds of ball mill grate type and overfall type due to different ways of discharging material Many types of grinding media are suitable for use in a ball mill each material having its
NOTE Grinding balls and media are sold on a per pound basis but ATTRITORS and DMQXMills are loaded by volume Therefore the more dense the media the more pounds of media required For instance a machine requiring only 40 lbs of stainless steel may require up to 80 lbs of tungsten carbide
The mill product can either be finished size ready for processing or an intermediate size ready for final grinding in a rod mill ball mill or pebble mill AGSAG 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
