Effect of agitator shaft direction on grinding performance

According to the simulations, in the vertical shaft configuration, the motion of the grinding media in the lower section through the vertical direction was inhibited by a too low velocity. On the other hand, the grinding media in the horizontal stirred mill moved more uniformly but with a lower collision energy.

Uses for an Old Lawn Vertical Shaft Motor

Uses for an Old Lawn Vertical Shaft Motor Most mower engines are in the 3-9 horsepower range, providing plenty of power for small projects. A vertical-shaft engine (as opposed to a horizontal shaft) presents a minor design challenge because most engine-driven projects use a horizontal input shaft. But a 90-degree gearbox can handle that.
