Mar 22 2018 · pin mill configuration. In a pin mill, the particle size is controlled by three parameters: feed rate, rotor speed and airflow. varying these parameters will have the following effects: increasing the feed rate will result in a coarser particle size while reducing the feed rate will have the opposite effect.
bead breakage contaminates the milling product and can clog the outlet of the mill, which can bring production to a standstill. during the formation process, both large and small beads collide with each other and stick together, resulting in the formation of and so-called satellites, as shown in fig.
media bead density has an evident but complex effect on stirred milling performance, depending on stirrer rotational speed and solids concentration. the effect of media bead size on the ultra-fine grinding of quartzite is relevant to the feed size. optimal ratio of media bead size to the median size of a feed is between 150 and 200.
