  • Fine grinding of silicon wafers designed experiments

    Fine grinding of silicon wafers designed experiments

    Three process parameters are chosen to study their effects and interactions: 1. Wheel speed: the rotational speed of the grinding wheel. 2. Chuck speed: the rotational speed of the chuck. It is the same as the rotational speed of the workpiece (wafer). 3. Feed-rate: the feed-rate of grinding wheel (spindle) towards the wafer. read more

    Coal comminution and sizing ScienceDirect

    Jan 01, 2013 Coal breakers, crushers and sizers. There are a number of breaking devices commonly used for reducing the topsize of ‘run-of-mine’ coal. These vary in their capacity and ability to deal with very hard, soft, or sticky coals, and in some cases they can also reject coarse rock that contaminates the coal. 9.2.1. Rotary breakersConventional design read more
