  • Modification Of Ball Mill For Efficient Work Finland

    modification of ball mill for efficient work finland. the peripheral discharge type of ballrod mill is a modification of the grate type and is recommended where a free gravity discharge is desired It is particularly applicable when production of too many fine particles is detrimental and a quick pass through the mill is desired and for dry ball mills are generally used to grind material inch and finer, down to the particle size of to microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced.
