The hammermill includes a housing, a working chamber defined by a polygonal screen, an inlet to the chamber, an outlet and a plurality of free-swinging hammers attached to a driven rotor. Support brackets extend the length of the housing and mount deflectors for eliminating tangential motion of materials being comminuted in the working chamber in the region of the deflectors. Side doors mount screen carriages for movement toward and away from the doors. In a closed position of the door, springs bias the screen carriages into engagement with wear-linings and the support brackets. The doors are pivotal away from the housing for access to the screens and the interior of the working chamber. A bottom screen carriage is movable toward and away from the chamber for access to the bottom screen sections.

The cooler/dryer includes a product inlet having an inlet discharge chute oscillatable about a horizontal axis corresponding to the direction of conveyance of the product within the dryer/cooler. The chute is at an opposite angle to the direction of conveyance and drops product onto a seal plate angled in the direction of conveyance. Through the combined oscillating motion of the chute and the opposed feed angles of the chute and seal plates in relation to the conveyor, an air seal between the conveyor and the seal plate and level distribution of product across the conveyor are provided. A secondary pivoting seal downstream from the inlet prevents air drawn in through the inlet along with the product from passing directly into the cooling/drying chamber.

A roll surface grinder includes a frame mounted on a carriage assembly for traversing movement between opposite sides of the frame in a direction parallel to the axis of the roll subject to grinding. The carriage assembly includes a linear drive system for controlling the transverse back-and-forth motion and speed of the carriage assembly along the frame during grinding. The carriage assembly includes a swing arm pivotally mounted on the frame and pivotal relative to the carriage assembly. The pivot angle of the swing arm relative to the carriage assembly can be adjusted manually to adjust the depth of the grinding.

Roll surface grinder

A hammermill having a polygon profile screen which provides for improved hammer impact and crushing efficiency. Particles in the working zone of the hammermill tend to be accelerated in the direction of hammer rotation. This acceleration lessens the speed differential between the hammer and the particle, which lessens the impact force and crushing efficiency. The polygonal screen inhibits this acceleration of particles in the working zone, due to flow interruptions caused by its irregular shape, thus increasing the particle-to-hammer speed differential and crushing efficiency.

Comminuting screen for hammermills

A manually actuated mechanism for roller mill feed gates that features both fine adjust and quick acting actuation. The mechanism consists of a hand wheel attached to an acme threaded rod, both of which are mounted in a bracket, the rod is attached to a clevis which is attached to a linkage and lever that is attached to the feed gate shaft. The fine adjust and quick action is accomplished by the lever which is spring loaded by tension spring. The lever has a half round acme nut that engages the acme threaded rod. The lever is normally held engaged to the rod by the spring for fine adjust but can be pulled by hand to release the rod for quick acting adjustment.

A feeder for comminuting equipment which combines inlet air and feed in lamina flow to minimize turbulent mixing by minimizing the air and feed convergence angles within the feeder.
