A comminution mill is described that includes a vertically oriented cylindrical housing with an intake chute in a top wall and an outlet chute in a bottom wall thereof. A rotatable shaft with a plurality of radially extending cables is disposed coaxially within the cylindrical housing. A plurality of studs extends inwardly from the wall of the housing to slow and collect materials flowing through the comminution mill. The studs can be withdrawn to discharge materials collected thereon. Slits are provided in the walls of the housing to enable the exit of particulate materials from the housing. A hood is provided overlying the slits on the exterior of the comminution mill for collecting the particulate material. Operation of the comminution mill provides a self-generated airflow and can be configured to separate, grind, and dry materials disposed therein.

Comminution mill with cable impact arms

A grinding mill is described. The grinding mill includes a vertically oriented cylindrical housing with an intake chute in a top wall and an outlet chute in a bottom wall thereof. A shaft is disposed coaxially within the cylindrical housing. Mounting plates are disposed along the length of the shaft. The cables are coupled to the mounting plates with opposite ends of each cable extending radially outwardly from the mounting plates toward but not into contact with an inner wall of the housing. A plurality of obstructing members extends inwardly from the wall of the housing to slow the flow of materials through the mill. Baffles are disposed on the interior wall of the housing to direct materials and airflow. The cables are rotated to contact and grind materials deposited into the grinding mill and to generate airflow through the mill.
