THE GRINDING CHARGE OF ROTARY MILLS Prof Dr Eng Gh Ene "Politehnica" University of Bucharest ABSTRACT This paper presents the achievemens of grinding charge for the tube mills with balls The author shows charactheristic size of grinding media charge: bulk density porosity filling degree Regarding this last size the
Chromium alloy is the main composition of casting steel ball with diameter of 6 mm to 140 mm According to different chromium content the grinding ball can be divided into three kinds namely low medium and high chromium balls The hardness of relevant balls are HRC≥45 HRC≥50 and HRC≥58 respectively with diameter of 6 mm to 140 mm
The fundamental disadvantage of the ball mill is the relatively high specific grinding energy demand In addition to the ball mill high-pressure grinding systems such as vertical roller mills (VRM) or high-pressure grinding rolls (HPGR) are in use today for cement grinding The specific energy demand of these grinding systems is comparatively
It is also faster to install than a traditional ball mill significantly reducing initial costs Lower operating cost Vertimill is an energy efficient grinding machine They tend to grind more efficiently than for example ball mills with feeds as coarse as 6 mm to products finer than 20 microns
To calculate grinding media charge for continuous type ball mill M = 0 000676 x D2 x L Example - To calculate grinding media charge for a 180 cm dia x 180 cm long batch type ball mill with Duralox 50 mm thick bricks Formula to be used is M = 0 000929 x D2 x L D = 180 - 10 = 170 cms
We have developed a method by which entire production lots are checked for metallurgical integrity keeping rejection to a minimum However products passing this process are guaranteed a maximum of 2% ball breakage in normal and correct mill operating conditions MINMETALS HAND FORGED BALLS 'ZERO CR 2' GRINDING MEDIA 80-125MM (PATENTED)
types of grinding mills (Table 1) Some devices such as ball mills are more suitable for coarse materials These mills use "large" media ranging in size from 20 mm in diameter and up to produce material from about ten microns to mesh sizes Attrition mills are
Rod mills are very similar to ball mills except they use long rods for grinding media The rods grind the ore by tumbling within the the mill To prevent the conditions leading to rod charge tangling the length to diameter ratio is maintained at 1 4 to 1 6 Rod mills accept feed up to about 50 mm (2 in ) and produce a product in the size range of 3000 to 270 mm (4 to 35 mesh)
