Cobalt Steel Ball End Mills with Two Milling Ends. With better heat and wear resistance than high-speed steel, these cobalt steel end mills can run at higher speeds and provide better performance on hard material, such as cast iron, hardened steel, titanium, and tool steel. When one end wears out, turn the tool around for a sharp edge.
frozen charge can drop and damage the mill body or the mill bearings. Air gap supervision (static - on stator and rotating - on rotor) The Ringmotor stator is supported on the floor or on concrete pedestal and the rotor poles are mounted on the mill flange (the rotor is the mill itself). To prevent the rotor from touching the stator, the air gap
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%.
