Plastic Turnover Box Granulator

Product Overview

The plastic turnover box granulator is a single-screw, specialized recycling granulation machine designed for rigid plastic sheet materials. It is tailored for pre-crushed rigid plastic fragments and can directly process various rigid plastic wastes such as HDPE, PP, and ABS, enabling integrated granulation operations. The equipment features a mature and stable single-screw design, producing uniform and consistent recycled pellets with impurity content ≤1% and particle size uniformity ≥95%. It supports 24-hour continuous production, with a capacity range of 100–2000 kg/h and a main motor power of 30–355 kW. As a customized product, the equipment has no fixed price; it is tailor-made according to the customer’s production requirements, adapting to diverse hard plastic recycling and processing scenarios, providing enterprises with an efficient and reliable solution for recycled pellet production.

Technical Principle

The plastic turnover box granulator employs a single-screw extrusion process, suitable for pre-crushed rigid plastic sheet materials. Material can be directly fed into the hopper and then into the barrel. Equipped with segmented ceramic heating bands, it achieves precise temperature control. Combined with the shear friction generated by screw rotation, this ensures thorough melting and plasticization of the rigid plastics, guaranteeing uniform material processing. After plasticization, the material passes through multi-stage filter dies, effectively removing sand, debris, and other impurities, while an exhaust system removes moisture and volatile components, ensuring the purity of the recycled pellets. Finally, the molten material is water-cooled and shaped, then cut into pellets to produce standard-compliant recycled plastic granules. The entire process is tightly integrated, with each step optimized to ensure both high granulation efficiency and superior pellet quality.

These enterprises commonly face the challenge of processing rigid plastic waste. The equipment helps them transform plastic waste into reusable recycled pellets, promoting resource circulation while reducing production costs and improving economic returns.

Applicable Materials and Application Scenarios

This equipment is suitable for a variety of pre-crushed rigid plastic wastes, including HDPE plastic bucket fragments, PE pipe scraps, PP turnover box pieces, ABS/PS industrial edge scraps, PC engineering plastic fragments, and more. In terms of application scenarios, it can be used for large-scale recycled pellet production at hard plastic recycling plants, provide backend granulation support for plastic crushing companies to directly process crushed plastic waste into marketable recycled pellets, enable daily-use plastic product manufacturers to recycle edge scraps generated during production, thus reducing raw material procurement costs, and assist industrial solid waste treatment facilities in converting hard plastic waste into valuable resources, aligning with environmental protection goals and circular economy principles.

Industry Pain Points Addressed

1. Solves the inefficiency of secondary handling after crushing: In traditional recycling granulation processes, crushed rigid materials must be transported to the granulation equipment, increasing logistics costs and extending production cycles. The plastic turnover box granulator directly interfaces with pre-crushed materials, eliminating the transport step and achieving efficient integration between crushing and granulation, thereby enhancing overall production efficiency.
2. Improves the issue of ordinary screws being unable to withstand hard material wear and high replacement costs: Conventional granulation equipment often uses screws with insufficient wear resistance, which quickly wear out when processing rigid plastics, necessitating frequent replacements and driving up maintenance expenses. This equipment features a nitrogen-treated, wear-resistant screw with a normal service life exceeding two years, reducing consumable replacement costs by 40% and effectively resolving this pain point.
3. Alleviates the complexity of equipment structures and the difficulty of routine maintenance: Some granulation equipment has complex designs that demand high technical skills from operators, making routine maintenance and troubleshooting challenging and adding to the enterprise’s operational burden. The plastic turnover box granulator adopts a simple, rational structural design, lowering the maintenance threshold and making it easy for operators to master, thus reducing labor and time costs associated with maintenance.
4.
