PURPOSE:To avoid accumulation of a fluid by disposing two rolls in parallel to each other at a suitable space therebetween at the lower opening portion of a hopper and turning both rolls to discharge particles to the outside, so that when the particles are discharged, the particles are kept from drifting in the hopper. CONSTITUTION:Two rolls 12, 13 having the same diameter and length are disposed in parallel to each other at a suitable space therebetween at the lower opening portion of a hopper 8. A branch member inverted V-shaped in section is disposed on the center line of the hopper 8 above the rolls 12, 13. Gears 14, 16, 17 are mounted on a driving shaft of a driving unit 3. When the driving unit 3 is driven, both rolls 12, 13 are rotated in the opposite direction to each other to discharge particles in the hopper 8 to the outside. At this time, control gates 6 disposed between the branch member 5 and both rolls 12, 13 are controlled to discharge the particles equally. In this arrangement, the particles in the hopper 8 can be kept from drifting so that retention or accumulation of particles due to a drift can be avoided. |
