ABSTRACT:
A mill suitable for use in an office environment because is constructed to collect particulates produced by the milling process without producing an undue amount of noise by this collection process. An isolation wall substantially eliminates particulate flow from the milling cavity into a motor/control cavity. A positive-pressure air flow through the motor/control cavity further reduces particulate transfer from the milling cavity into the motor/control cavity and draws these particulates into a particulate collection tray.
