Description: |
| Abstract:
his invention relates to sugarcane mills of the type in which some of the rolls have formed on their surface ridges or teeth with intervening channels so arranged circumferentially around the rolls that when the rolls are geared together the circumferential teeth on one roll project into the circumferential channels i the other roll with which it engages. This type of roll is efficient in that it effectively spits, breaks and crushes the cane and also allows for a free escape of the juice down the circumferential channels of the lower roil on the side of the intermeshing rollers from which the canes enter, and further as the channels are circular the possibility of their becoming clogged by portions of the broken cane or megass sticking therein is prevented by scrapers so carried that they project into the channels; but these rolls are not so efficient as they might be in that the teeth are apt once they have split the portion of cane between them to slip through it without dragging it forward. In. order therefore to overcome this objection and obtain and efficient biting effect on the cane, which will insure a regular forward movement thereof, the roil, according to the present invention, has formed upon its surface series of short zig-zag grooves extending longitudinally from end to end of the roll and so spaced apart around the circumference of the roll that there is always a portion of one of the series of grooves opposite the point where the rolls intermesh.
Claim:
A roll for sugar cane mills having circumferential teeth with intervening channels formed on it's surface, in combination with zigzag grooves extending longitudinally of the roll and arranged to intersect said circumferential teeth at all points circumferentially of the roll. |
