Introduction to the purchasing guide of granulator

1. Use a sub-machine and twin-screw feeding.
2. The reduction gearbox must be good, the gears inside must be heat treated, and the bearings must be adjustable.
3. The gearbox, screw, barrel, machine head and wear parts must be strength-treated, and the service life is guaranteed to be more than 1 year.
4. The main components should be made of standard materials.
5. Purchase the reducer and motor as a set produced by a professional manufacturer instead of those assembled by the granulator manufacturer yourself.
6. There must be a power distribution work cabinet.
7. The most critical thing about the equipment is that the quality of the screw and barrel is good.
8. The washing machine must be in continuous production without stopping to change water and use a cleaning pool, otherwise the efficiency will be extremely low.
9. Heating should be done in sections, and sectioned heating should be uniform and controllable.
10. There must be a supporting waste plastic cleaning machine that uses circulating water and does not need to discharge sewage.
11. High efficiency and energy saving.
12. The length-to-diameter ratio of the machine cannot exceed 20 (16:1-20:1 is appropriate, which means that the screw length is 16-20 times the screw diameter).
13. The model should not be smaller than 100. The larger the size, the higher the output.
14. There must be dual exhausts.
15. The heating power of the granulator flange (die head) is very important and should be designed at 2.5W per square centimeter (cross-sectional area).
