Water turbine - Wikipedia

A water turbine is a rotary machine that converts kinetic energy and potential energy of water into mechanical work. Water turbines were developed in the 19th century and were widely used for industrial power prior to electrical grids. Now they are mostly used for electric power generation. Water turbines are mostly found in dams to generate ...

Progress with Grinding Aids for Vertical Roller Mills

The differential pressure between the inlet and outlet of the mill (ΔP mill) is an important process variable for the testing of grinding aids. ΔP mill reflects the load and the filling level of the mill. At unchanged separator settings, the increase of ΔP mill indicates more internal circulations and more fines.

Progress with Grinding Aids for Vertical Roller Mills

ΔP mill reflects the load and the filling level of the mill. At unchanged separator settings, the increase of ΔP mill indicates more internal circulations and more fines. As a result of the higher ΔP mill, the mill vibration increases (8-10mm/s), which results in a good opportunity to test the effect of the grinding aid.
