Machines
In Progress
We are experimenting with different methods to make film plastics into more dense granules to make it feed into the extrusion machine. We are designing a machine called a agglomeration machine. We have designed a machine based on what we have seen on YT. Plastic is fed into a tub with a rapidly spinning blade on the bottom. It is similar to a very large food processor. The plastic gets chopped to small particles, it also gets very hot due to friction from the spinning blades that start to soften and melt the plastic. The plastic then sticks together like a dough. It is then cooled rapidly, and the resulting chunks of plastic are then chopped to granules in the same machine. Plastic is then discharged out the machine thru a gate in the bottom with centrifugal force. We are able to get the plastic to get hot and turn to a dough in as little as 9 min per batch. We have added in water to rapidly cool the plastic, and we have added in scoops of cooled shredded plastic.

Operation of a commercial style agglomeration machine

Created 1yCreated over 1 year ago
Here a man is explaining in Spanish how he converts PE bags into granules. It appears that the entire cycle time for him is 16 min to process that large tub. I do not know the HP he has in the machine or the blade type and RPM. However it was interesting that he did not add water like the machine operators from China. He also described the plastic turning into a sort of dough. Which I experienced in the operation of my machine. It would run and then over the course of about 30 seconds start to hit the agglomeration point, and turn into a dough. this operator then dumped in a portion of the previous batch of granules, which absorbed the heat, and then the big chunks of now semi solidified material would get chopped up in granules in the machine. Which I did, and got a similar result using shredded foil multi layer plastics. However my machine at this point on the best run so far, lost the key on the shafting, and the pulley spun. Shafting is out for repair
