Waterwheel

The horizontal-wheel mill (sometimes called a Norse or Greek mill) also required little auxiliary construction, but it was suited for grinding because the upper millstone was fixed upon the vertical shaft. The mill, however, could only be used where the current flow was suitable for grinding. The geared vertical-wheel mill was more versatile.

A study of comminution in a vertical stirred ball mill.

Although during coarse grinds the media wear was higher in the stirred ball mill than in the tumbling mill, it became less so as grinding proceeded and for a product median size of 4.8 microns it was the same.

Sep 28, 2018Inverse dynamics is a technique in which measured kinematics and, possibly, external forces are used to calculate net joint torques in a rigid body linked segment model. However, kinematics and forces are usually not consistent due to incorrect modelling assumptions and measurement errors. This is commonly resolved by introducing 'residual forces and torques' which compensate for this
