  • High efficiency impact mill
    Patent number: 12138631
    Abstract: An impact mill using hammers to strike particles and reduce their size as the material progresses through a grinding chamber. Baffles are provided in the grinding chamber, adjacent the interior wall thereof, concentrically about the drive shaft of the mill. The baffles are adjacent to the hammers in the area of hammer sweep and form a path for the material using the flow of air through the mill and the swing of hammers to keep material from falling within the mill and remaining in the hammer sweep area. A variable speed motor varies the rate of movement of the hammers to increase or decrease the rate of strike of hammers to more efficiently and effectively reduce the material passing therethrough. The baffles can be retrofit into existing mills and can be created in angular sections with the lining of the grinding chamber for modular installation and removal.
