Ball mill. A typical type of fine grinder is the ball mill.A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.
too much spatter Miller Welding Discussion Forums
what causes exsesive spatter when mig welding? im using a miller 211 and there is a ton of spatter rather large dingle balls too. ive watched videos and they seem to weld with very little spatter and no clean up. when i weld i gota knock off a bunch of dingle balls. how do i dial in my machine like that?
