It is evident that grinding in a vertical stirred mill with a double helical screw is more efficient than that using a pin type stirrer in terms of the product size distribution and the specific energy consumption. It is concluded that the double helical screw design provides better energy efficiency compared to the pin type stirrer design.

Re: Haas minimill FEA. Hi Jag A modern CNC VMC has a stiffness in the order of 150um/N. This is loaded at the end of the toolholder and restrained at the bed somehow. Unfortunately there is not a standard method for the test. Small benchtop mills are <10um/N. Something like a taig is <2um/N.

SMD has a modular design ensuring faster installation and reducing installation costs. The vertical arrangement, on the other hand, allows the drive train to be entirely supported by the mill body which leads to a small footprint and simple foundation. Furthermore, the vertical arrangement does not require any slurry seals or inlet feed pressure.

A verticalaxis wind turbine ( VAWT) is a type of wind turbine where the main rotor shaft is set transverse to the wind while the main components are located at the base of the turbine. This arrangement allows the generator and gearbox to be located close to the ground, facilitating service and repair.
