The variable frequency drive allows the operator to adjust hammer tip speed while requiring minimum idle time. It is hypothesized that lowering the tip speed of the hammers should result in a larger particle size when using the same screen hole diameter, thus allowing for more flexibility in particle size with any given screen size.
