1 . A horizontal shaft impactor comprising:
a housing having a feed opening O F ; and
a feed plate defining a lower end of said feed opening O F , said feed plate having an adjustable feed angle.
2 . The impactor of claim 1 , wherein said feed plate is pivotally coupled to said housing.
3 . The impactor of claim 2 , further comprising:
a first plurality of replaceable side plates configured to be removably mounted to said housing, the first plurality of replaceable side plates configured to support said feed plate in a first plane;
a second plurality of replaceable side plates configured to be removably mounted to said housing, the second plurality of replaceable side plates configured to support said feed plate in a second plane angularly offset from said first plane.
4 . The impactor of claim 1 , further comprising:
a curtain, said curtain pivotally coupled to said housing in a first position for pivoting about a first horizontal axis, said curtain pivotally coupled to said housing in a second position for pivoting about a second horizontal axis offset from said first horizontal axis.
5 . The impactor of claim 4 , further comprising a curtain rod removably supported on said housing.
6 . The impactor of claim 5 , wherein said curtain comprises a first opening and a second opening, wherein said first opening is configured to at least partially support said curtain in said first position, wherein said second opening is configured to at least partially support said curtain in said second position.
7 . The impactor of claim 5 , further comprising: an actuator supported on said housing, wherein said curtain comprises a first and second pivot, said actuator being coupled to said first pivot in said first position, said actuator being coupled to said second pivot in said second position.
8 . A horizontal shaft impactor comprising:
a housing having a feed opening O F ;
a feed plate defining a lower end of said feed opening O F ;
a curtain, said curtain pivotally coupled to said housing in a first position for pivoting about a first horizontal axis, said curtain pivotally coupled to said housing in a second position for pivoting about a second horizontal axis offset from said first horizontal axis; and
a curtain rod removably supported on said housing, wherein said curtain comprises a first opening and a second opening, wherein said first opening is configured to at least partially support said curtain in said first position, wherein said second opening is configured to at least partially support said curtain in said second position.
9 . The impactor of claim 8 , further comprising:
an actuator supported on said housing, wherein said curtain comprises a first and second pivot, said actuator being coupled to said first pivot in said first position, said actuator being coupled to said second pivot in said second position.
10 . The impactor of claim 8 , wherein said feed plate is pivotally coupled to said housing.
11 . The impactor of claim 10 , wherein said feed plate has an adjustable feed angle.
12 . The impactor of claim 11 , further comprising:
a first plurality of replaceable side plates configured to be removably mounted to said housing, the first plurality of replaceable side plates configured to support said feed plate in a first plane;
a second plurality of replaceable side plates configured to be removably mounted to said housing, the second plurality of replaceable side plates configured to support said feed plate in a second plane angularly offset from said first plane.
13 . A horizontal shaft impactor comprising:
a housing having a feed opening O F ; and
a first plurality of replaceable side plates configured to be removably mounted to said housing, the first plurality of replaceable side plates configured to support said feed plate in a first plane;
a feed plate defining a lower end of said feed opening O F , said feed plate being pivotally coupled to said housing.
14 . The impactor of claim 13 , wherein said feed plate is pivotally adjustable between at least a first position and a second position.
15 . The impactor of claim 14 , further comprising:
a second plurality of replaceable side plates configured to be removably mounted to said housing, the second plurality of replaceable side plates configured to support said feed plate in a second plane angularly offset from said first plane.
