How to Adjust Ring Die

Adjust the gap between ring die and the roller

Take off the top cover of the pellet machine, unscrew the hollow bolt, you can see two nuts. Screw and unscrew the nuts, then you can turn the roller. Screw the hollow bolt after gap adjusted, connect with oil system. Please pay attention, the gap should be very mall, to make sure that roller “just can turn”. If pellets don’t go out, the problem may be on the gap. Can screw the nuts to the end, and every time unscrew 1/4 or 1/3 circle. Every time can start the pellet machine on 1 second, listen to the sound, if the gap is too small, there will be a sharp noise. Keep trying, until you find the correct gap.

Ps: For production the gap should be as small as possible (under the premise of normal production), when changing roller or changing the ring die, the gap should be adjusted as big as possible.

Change Roller

Take off the cover, take off the oil pipes and unscrew the bolts; remove the nuts and pressure adjusting set, feeding plate, and then the whole hollow shaft can be take out for replacement.

Change Ring Die

Take off the cover and adjust the gap as big as possible, unscrew all the bolts and nuts, remove oil pipes, take out the cover plate with the whole feeding system; release rollers assembly, eject the taper pressure block through the thread hole. Under the ring die in the bearing chamber, there are 3 or 4 holes of 26mm diameter, using jack to raise the ring die from these holes and lift the die by lifting hole. Then put a new ring die in.

When adjust and replace the machine parts, need to keep the machine clean. You can use a vacuum cleaner for removing the remained material.
