1. Use a master-slave granulator with twin screw feed.
2. The gearbox must be of high quality, with heat-treated gears and adjustable bearings.
3. The gearbox, screw, barrel, die head, and wear parts must be strength-treated, with a lifespan of at least one year.
4. Major components must be made of standard materials.
5. Purchase a complete set of reducers and motors from a professional manufacturer; do not buy granulator sets assembled by the manufacturer.
6. A power distribution cabinet is required.
7. The most critical components are the high-quality screw and barrel.
8. The washing machine must operate continuously without stopping for water changes; use a washing water tank, otherwise efficiency will be extremely low.
9. Heating should be segmented, and each segment should be uniform and controllable.
10. A matching waste plastic washing machine with circulating water is required, eliminating the need for wastewater discharge.
11. High efficiency and energy saving. 12. The length-to-diameter ratio of the machine should not exceed 20 (ideally between 16:1 and 20:1, meaning the screw length is 16 to 20 times the screw diameter).
13. The model number should not be less than 100; larger numbers result in higher output.
14. Dual venting is required.
15. The heating power of the granulator flange (die head) is crucial; it should be designed at 2.5W per square centimeter (cross-sectional area).
