the solutions to the uneven discharge size of there are mainly two main reasons which lead to the non-uniform discharge of ball mill: too much water content or the inner temperature is too high. too much water content occurred when 'full mill', too high temperature caused by 'bag ball'. these two phenomena can make the grinding ability decline. at this time, the grinding sound will be low and deep, the current decline in ball mill. if it

how we discharge the ball mill - strzelnica a ball mill grinds ores and other materials to a typical product size of when the l/d ratio is 2 to 1 or greater, we refer to the mill as a tube mill. trunnion overflow discharge a trunnion overflow mill has an open discharge end. material flows ball mills operate either in open or closed circuit.

rod mills, how they function - mine engineer.com rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. for an equivalent grind, a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore. the rod charge must be maintained in good working condition, and broken and worn rods must be removed. rod mills usually require greater operator attention. it
