VERTICAL MILL

摘要

In the disclosed vertical mill, grinding efficiency is improved because solids such as biomass are ground efficiently. In the disclosed vertical mill, a grinding table (13) is supported so as to be rotated by being driven on a rotation shaft axis disposed vertically inside a housing (11), a grinding roller (18) capable of rotation coupled with the rotation of the grinding table (13) is arranged above and opposite to the grinding table (13), and a roller oscillating mechanism (19) is provided capable of oscillating the grinding roller (18) along the surface of the grinding table (13) and in a direction different from the rotation direction thereof.
