Abstract
This invention relates to an improved airflow hammermill assembly for grinding materials. More particularly, this invention relates to an improved airflow hammermill assembly for processing vegetable meals and cereal grains. The improved airflow hammermill assembly incorporates one or more diverging ducts communicating with the hammermill housing to provide a more uniform negative pressure within the housing. The improved airflow hammermill assembly allows increased throughput and energy savings.
Claims15
A hammermill, comprising:
- (a) a housing having an inlet, an outlet, and a plurality of side walls;
- (b) a rotor mounted within the housing on a shaft for rotation about an axis;
- (c) a classification grid within the housing substantially surrounding the rotor and defining an inner grinding chamber and an outer collection zone;
- (d) a plurality of impact members attached to and disposed longitudinally along the rotor within the inner grinding chamber;
- (e) a diverging duct mounted on one of the housing side walls, the diverging duct having a discharge end and an entrance end communicating with the outer collection zone;
- and
- (f) a blower communicating with the housing outlet and the diverging duct discharge end to establish negative pressure within the housing and facilitate continuous flow of ground material out of the hammermill.
