Size Distribution of Grinding Media (Balls) in a Mill
At high speed, they are in the centre This applies to all types of grinding media, eg pebbles, ball or rods This segregation is a result of the fact that at low speed, the force of gravity is stronger than the centrifugal force, so that the grinding media move around the core of the charge The relative movement of the material being ground is greatest at the top of the 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 smallscale tests are applied to this task A plant media sizing methodology, and industrial case studies, are provided BackgroundBall mill media optimization Metcom TechCurrent ball milling theory suggests that grinding capacity is influenced by the size of balls charged to the mill In selecting the appropriate ball charge, the first objective is to determine that ball size which will grind the coarse particles most efficiently This size should be the largest ball size charged to the mill The second objective is to provide the correct ball size distribution to Grinding Media 911Metallurgist

20/02/2017 Grinding by use of nearly spherical shaped grinding media is termed ball milling Strictly speaking, such media are made of steel or iron When iron contamination is detrimental, porcelain or natural nonmetallic materials are used and are referred to as pebbles When ore particles are used as grinding media this is known as autogenous grinding13/02/2017 If finer grinding is wanted two or three stage grinding is advisable as for instant primary rod mill with 75—100 mm (3″—4″) rods, secondary ball mill with 25—40 mm(1″—1½”) balls and possibly tertiary ball mill with 20 mm (¾”) balls or cylpebs To obtain a close size distribution in the fine range the specific surface of the grinding media should be as high as Ball Mills Mineral Processing MetallurgyGrinding is the process of achieving particle size reduction through attrition and compressive forces at the granular level The grinding media in a ball mill is typically steel or ceramic balls of varying sizes, depending on the feed size, work index of the ore and the size reduction and distribution required in the dischargeBALL MILL AND BALL CHARGING SYSTEMS AUSTRALIA BHT Group
