عرض المزيدBall 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%.
عرض المزيدAnother benefit of the way the ball end mill is designed is that it can handle very high feed rates, meaning it can mill the material very quickly. This gives it great productivity for use in today's milling machines. The smooth geometry of the cutting tip also translates into lower cutting forces, giving the cutter added strength under pressure.
