Abstract

PURPOSE:To enable pellets nonuniform in shape or size produced in a beginning period of pelletization to be discharged to the exterior and prevent the interior of a pump from being damaged or clogged by connecting a jet pump to the lower end of a cooling water tank through a three-way cock having a draining port. CONSTITUTION:Pellets formed by a rotary cutter 5 are scattered into a cooling water tank 6 provided in the vicinity of the cutter 5. A flow of water fed under pressure by a water pump 11 is supplied through a discharging port 11a and a piping 11f to a jet pump 13. In a beginning period of an operation of a pelletizer 1, favorable pelletization can not be achieved stably. In such a situation, a three-way cock 12 is switched to a draining port 12a, whereby the pellets scattered into the tank 6 are discharged to the exterior through the draining port 12a of the cock 12, together with the water contained in the tank 6. After stable pelletization comes to be achieved, the cock 12 is switched to the side of the jet pump 13, whereby the pellets favorably formed are passed, together with the water in the tank 6, through a suction port 13a to be pressurized by the jet pump 13, and are fed under pressure to the next step.

Along with this movement, the extension portion 3C of the cutter shaft 3 moves up and down, and the vertical position of the rotary cutter 5 with respect to the die 2 is adjusted. On the other hand, when the electric motor 9 is operated to rotate the cylindrical shaft 3d, the cutter shaft 3 whose rotation is restrained by this and the splines 3e and 3f also rotates. Even during this rotation, the distance between the rotary cutter 5 and the die 2 can be adjusted by rotating the adjustment screw γC as described above. At this time, if we connect an ammeter 90 to the electric circuit of the motor 9 and pay attention to the reading of this ammeter 90, we can see that the greater the degree of contact between the rotary cutter 5 and the die 2, the higher the current value.
Adjustment becomes easier.
