The rule of thumb for mill scale up is approximately 1 √D√d where d is the diameter of the smaller mill and D the diameter of the larger mill So going from a 12 lab scale mill to a 24 mill 1 √24√12 04 so the larger mill may perform as much as 40 more efficiently The inverse will be applicable to scaling a mill down to a smaller diameter...As a leading global manufacturer of crushing equipment, milling equipment,dressing equipment,drying equipment and briquette equipment etc. we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete plant plan.

Apr 01 1988 · Such a correlation is needed for the scaleup design of large ball mills In order to accomplish such a correlation we analyzed not only our own RTD data but also the data of others The data includes mill diameters ranging from 04 to 55 m 13 to 15 ft and lengths ranging from 04 to 98 m 13 to 32 ft with ball sizes ranging from 381 to 762 mm 15 to 30 inches
Very large tonnages can be ground with these ball mills because they are very effective material handling devices Ball mills are rated by power rather than capacity Today the largest ball mill in operation is 853 m diameter and 1341 m long with a corresponding motor power of 22 MW Toromocho private communications
6 PREDICTABLE SCALE UP – Scale up from small to large mills is very predictable Ball milling is one of the few unit operations that actual improve in performance and efficiency with increasing size The ABBE Slice Mill is the same as the product mill and can replicate all mill operating parameters but with very little product
1 Ball mill has a wide range of applications It can grind metal ore and nonmental ores which is suitable for hard materials such as quartz gold ore copper ore iron ore potash feldspar etc 2 Ball mill is also can be applied in the industries such as cement construction materials fireproofing materials chemical fertilizer ore
The balls which could be of different diameter occupy 30 – 50 of the mill volume and its size depends on the feed and mill size The large balls tend to break down the coarse feed materials and the smaller balls help to form fine product by reducing void spaces between the balls Ball mills grind material by impact and attrition
