Abstract:
This invention has reference to grinding- mills, and relates more particularly to sweep-mills in which the grinders have their operating-surfaces arranged at about an angle of forty-five degrees. In order to grind corn and other grains, it has frequently been found necessary to set the grinders quite close together. Otherwise the grain will drop down from between them before being properly ground and crushed. Such grinding is faulty and incomplete, and in addition thereto the grinder-surfaces, owing to their close proximity and in many instances actual contact, soon become so worn as to be useless, putting the millowner to the expense of renewing them.
Claim:
The combination with vertical cone grinding surfaces, of a vertically and horizontally adjustable retainer supported below and adjacent the exit-space of the grinding-surfaces. |
