Get PriceBall mills are employed in either primary or secondary grinding applications. In primary applications, they receive their feed from crushers, and in secondary applications, they receive their feed from rod mills, AG mills, or SAG mills. Sign in to download full-size image Figure
Feb 13, 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″—1 ”) balls and possibly tertiary ball mill with 20 mm ( ”) balls or cylpebs
Get PriceJan 30, 2018 The ball miller machine is a tumbling mill that uses steel milling balls as the grinding media, applied in either primary grinding or secondary grinding applications. The feed can be dry or wet, as for dry materials process, the shell dustproof to minimize the dust pollution
Get PriceSecondary Mills The standard method for sizing secondary ball mills (usually the overflow type) in AG/SAG circuits follows published mill supplier information with aspect ratios in the range 1:1.5 to 1:2.0, depending upon product sizing and pulp flow, i.e., the highest expected circulating loads (Morrell, 2001)

Get PriceSMALL C. I. W. BALL MILL. The CIW is a Small Ball Mill that’s belt driven, rigid bearing, wet grinding, trunnion or grate discharge type mill with friction clutch pulley and welded steel shell. The 7 and 8 foot diameter mills are of flange ring construction with cut gears while all other sizes have cast tooth gears
Get PriceMaintaining the work balance between the primary SAG mill and secondary ball mill(s) is an overlooked bottleneck, and thus opportunity, in an increasing number of circuits worldwide. As circuit capacities are expanded by ‘releasing’the SAG mill bottleneck, the work is progressively passed on to the downstream ball mills
Get PriceBall mill is the key equipment for secondary grinding after crushing.The Ball mill can be divided into lattice type and overflow type according to different beneficiation methods, and this machine is two lattice-type ball mill

Get PriceDRA Global were subsequently engaged to provide detailed design of Phases 2 and 3 of the project expansion which included design of a new milling building (7.6MW primary and 6.0MW secondary ball mills) and a new flotation circuit comprising 5 x 100m3 flotation cells and associated ancillaries
Get PriceThe mill feed silos hold 1,500 t each. Material from the silos is fed to two primary 9.5 ft x 12 ft Kopper ball mills, which each operate in closed circuit with the secondary ball mills. Primary Mill 1 operates with three secondary mills (i.e., Hardinge 8 ft x 4 ft, Comesa 8 ft x 4 ft, and Comesa 6 ft x 7 ft)
Get PriceNov 18, 2008 Basic principle Ball mill is generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system. There is a specific operating speed for most efficient grinding
