    How Speed Of The Ball Mill Affect Grinding Efficiency

    The ball mills of grinding media types, for example, tumbling ball mill, planetary ball mill and stirred grinding media mill are very useful grinding machines used in many fields [13,14]. Further , these mills have been used for activating the mechanical effects as well as the size reduction of materials. The motion of balls in the mill.One of the most efficient devices for micronizing coal is a stirred ball mill. Using the laboratory mill with a relatively high media loading (80 filling), small grinding media (less than 1 mm diameter), and three coals, effects of some parameters such as media size, stirring speed, and pulp density on the grinding of coals have been studied.

  • Effect Of Operating Parameters In Stirred Ball Mill

    Effect Of Operating Parameters In Stirred Ball Mill

    The grinding principle of the rotary ball mill is different from that of the vibration ball mill, which uses the high frequency vibration of the cylinder to grind the materials, and it is also different from the attritor ball mill which uses the agitator to stir the grinding media to grind the materials. The rotary ball mill uses the rotary motion of the cylinder to drive the grinding steel.Al., 2005). In stirred mills there are no free falling possibilities for grinding media, meaning that impact action does not occur. The bead size is small, typically 1 to 6 mm which means a large amount of contacts and high grinding efficiency especially in the finest range, where ball mills are not effective or cannot reach P80 10 to 40 m.

    The size, shape and matching ratio of the grind media can affect the grinding result. Generally speaking, the bigger the mill media is, the finer the grinding powder is. A proper match ratio of grind medias and proper adjustment of rotation speed can get better grinding effect.The stirred ball mill is regarded as one of the most efficient devices for micronizing coal. Using a 13.4 cm batch mill, the optimum operating conditions have been determined in terms of media size, feed size and media type.
