The chute feeder can be installed on the ground or onto discharge port of ore bin. The chute bottom plates do the reciprocating movement, the movement frequency is 20-60 times/min and the stroke is 20-200mm. Stroke can be adjusted by the eccentric wheel; the eccentric throw is half of the stroke. According to experience of some mine sites, the eccentric throw should no less than 30mm for cohesive ore. The chute width is 2-2.5 times of maximum feeding granularity. The biggest chute feeder can supply ore with granularity less than 500mm. The most common specification is 980*1240 chute feeder, with feeding granularity between 350-0mm, which is the best partner of 400*600 jaw crusher.
