    Ball mills give a controlled final grind and produce flotation feed of a uniform size Ball mills tumble iron or steel balls with the ore The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds The feed to ball mills (dry basis) is typically 75 vol% ore and 25% steel The ball mill is operated in closed circuit with a particlesize measurement· The size of the balls used for grinding depends on the size of the material entering the mill; they should be just large enough to break the biggest lump of ore likely to be encountered Balls of 5in diameter are the largest in common use, but they are only suitable for coarse feeds of 1in size or over Balls from 3 to 4 in in diameter are ordinarily employed in mills when the feedBall Mills Mineral Processing & MetallurgyFor small to large scale operations, DOVE Ball Mills are supplied in 17 models, capacity range of (03 TPH – 80 TPH) With over 50 years experience in Grinding Mill Machine fabrication, DOVE Ball Mills as critical component of DOVE Crushing plants are designed with highest quality of material for long life and minimum maintenance, to grind ores to 35 mesh or finer DOVE Ball Mill, Hard RockBall Mill | Ball Mills | Wet & Dry Grinding | DOVE
