Fully Automatic 210 Type Drip Irrigation Belt Three-step Machine, Waste PE Drip Irrigation Belt Special Granulation Recycling Production Line

The 210 type drip irrigation belt three-step machine is a three-stage graded plasticizing and granulation equipment specially developed for waste farmland drip irrigation belts, micro-spray belts and PE hoses. Adopting a three-series extrusion process of main machine, secondary machine and tertiary machine, the complete machine is integrated with non-stop hydraulic screen changing, constant-temperature electromagnetic heating, high-speed friction cleaning, vibration screening and dehydration storage configurations. It specifically solves the industry pain points of drip irrigation belts, such as thin and fragile texture, high sediment content, numerous aging impurities, uneven plasticization and frequent strip breakage of ordinary granulators, serving as the core special equipment for large-scale regeneration of agricultural plastic waste.

Traditional single-step and two-step granulation equipment generally suffers from incomplete plasticization, unclean impurity filtration, high-temperature carbonization and unstable discharging when processing drip irrigation belt materials. The produced particles have poor appearance and low purity and cannot be reused in the secondary production of agricultural pipes. In contrast, the 210 type drip irrigation belt three-step machine realizes progressive melting, exhaust, filtration and fine plasticization through three-stage graded plasticization. Equipped with high-frequency heat-treated screws and an intelligent constant temperature system, it perfectly adapts to the material characteristics of PE drip irrigation belts including low density, high impurity and easy aging. It supports stable mass production, producing dense and transparent recycled particles with extremely low impurity content, fully meeting the production standards of high-end recycled particles.
