Abstract
A wood chip classifier and classification system in which chips are separated into a plurality of fractions according to chip size in an apparatus having an automatically adjustable hole spacing for first removing from a sample chips in the fraction smallest in size, and subsequently removing therefrom fractions containing chips of progressively larger size. A particularly suitable apparatus includes a rotating drum for receiving chips on the inside thereof, with the perimeter of the drum being formed from a plurality of spaced rods, and the spacing between the rods being adjustable.
Claims9
A chip classifier comprising;
- a drum for receiving a volume of chips on the inside thereof;
- said drum including a plurality of rods defining adjustable spaces at the perimeter of said drum, each of said rods having a longitudinal axis, said spaces enabling chips of predetermined thickness to pass from the inside of said drum through said spaces to the outside of said drum;
- drive means for rotating said drum;
- and
- an adjustment mechanism controlling the radial position of at least some of said rods defining adjustable spaces at the perimeter of said drum for varying the thickness of chips passing from the inside of said drum to the outside of said drum by varying the size of spaces defined, said adjustment mechanism including means for moving the longitudinal axis of at least some of said rods along a substantially radial path.
