    Rod mills, how they function - Mine Engineer.Com

    Rod operate at lower speed than since the rods are rolled and not cascaded. For an equivalent grind, a rod uses less steel than a because of the lower speed and better contact between the media and ore. The rod charge must be maintained in working condition, and broken and worn rods must be removed.

    Ball Mill Operation. Ball mills ride on steel tires or supported on both ends by trunnions. Girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive. The prime movers are usually synchronized motors. During rotation, a portion of the charge is lifted along the inside perimeter.

    A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either horizontal or at a small angle to the horizontal. It is partially filled with balls. The grinding media are the …

    Grinding in Ball Mills: Modeling and Process Control

    The speed of rotation of the mill determines three basic types of operation modes: slow rotation cascading, fast rotation cataracting and very fast rotation centrifugation. Each type is characterized by a specific trajectory of motion of the charge in the mill and a different impact of the milling bodies on the ground material.
