Hardinge Conical Mill Capacity
The following conclusions on the work of the Hardinge mill are based on data furnished to the writer by the Hardinge Conical Mill Co. in the form of the mesh cards hereto appended. Energy units (E. U.) and relative mechanical efficiencies (R. M. E.) are computed by the volume method of Stadler. Screen apertures used are the average apertures of testing screens of the meshes given. Card
