High-End 125 Type Granulator, Small Fully Automatic Plastic Recycling Granulation Equipment with High Profit

In the fields of small-scale plastic recycling, sample modification and scrap recycling, a structurally stable, precisely temperature-controlled and low-energy-consumption 125 type granulator serves as the core essential equipment for small processing factories and new material R&D enterprises. Many small granulation devices suffer from wear-prone screws, uneven heating, high noise, troublesome screen replacement and uneven pelletizing, resulting in failed trial production, high defective rates in mass production and frequent equipment shutdowns. Our newly upgraded high-end 125 type granulator adopts industrial-grade wear-resistant accessories, dual-group constant temperature heating, variable frequency speed regulation system and national standard electric control configuration, forming a fully closed-loop automatic operation process from extrusion, filtration and cooling to pelletizing and material storage. It perfectly adapts to small-batch, high-precision and high-frequency granulation production scenarios.

This 125 type granulator features five core advantages: wear resistance and durability, constant temperature plasticization, low noise and energy saving, simple operation and regular finished products. Different from ordinary low-end small granulators, all core extrusion components are treated with nitriding reinforcement, featuring high hardness, wear resistance and high temperature resistance. They are not prone to strain, carbon deposition and deformation during long-term processing of waste plastics, modified plastics and plastic scraps. The dual-mode heating system balances heating speed and temperature stability, and the variable frequency speed regulation adapts to the extrusion speed of different materials. It can stably produce high-quality recycled plastic particles with uniform appearance, no black spots and no bubbles, which is very suitable for start-up granulation factories, material sample testing and small-batch customized production.

The equipment supports a wide range of raw materials, including PP/PE films, plastic scraps, crushed flake materials and modified mixed plastics. It is widely applied in small plastic recycling processing plants, new material laboratories, edge scrap recycling of plastic product factories and modified particle trial production. With a high degree of full-process automation, it can be operated by a single worker. Featuring fast startup, low failure rate, low production threshold and short payback period, it is a highly cost-effective main granulation equipment in the current small-scale plastic recycling industry.

1. Complete Equipment Technical Parameters & Accessory Functions and Values

125 Type Granulator Main Host: Equipped with 225 type hard-tooth low-noise reducer, it delivers large transmission torque, stable operation, low noise and no slipping or power loss, which is more suitable for long-term heavy-duty extrusion working conditions than ordinary reducers. It is fitted with a 125×2800mm nitrided screw and a 159×2800mm nitrided barrel with overall nitriding treatment, which greatly improves surface hardness, material wear resistance and high-temperature oxidation resistance. It effectively prevents screw strain and barrel carbon deposition and greatly extends service life. Powered by a 37KW special main motor with sufficient power and stable extrusion pressure, it ensures uniform material plasticization. The heating system adopts a combined set of 60KW electromagnetic heating and conventional heating coil, featuring fast heating, wide temperature control range and good heat preservation performance, balancing energy saving and plasticization effects to adapt to the melting requirements of different plastic materials.

360 Type Automatic Screen Changer Head: Equipped with a large filter area screen with a diameter of 310mm and an adjustable 2.2KW-6 head motor, it boasts strong impurity interception capability, which can effectively filter sediment, black spots and impurities inside plastics and improve particle purity. The electric screen changing design eliminates the need for shutdown and disassembly for screen replacement, greatly reducing downtime, improving production continuity and solving the industry pain point of frequent screen blockage and shutdown cleaning for small granulators.

Stainless Steel Cooling Water Tank: With a specification of 4000×350×260mm, the whole tank is made of stainless steel, which is corrosion-resistant, rust-proof and keeps water clean. The sufficient cooling tank length enables uniform and full cooling of extruded plastic strips, ensuring uniform hardness, no deformation and no adhesion of plastic strips, laying a foundation for subsequent precise pelletizing and avoiding uneven particle length and adhesion agglomeration.

180 Type Alloy Rotary Cutter Pelletizer: Adopts high-hardness alloy rotary cutter with wear resistance, impact resistance, flat incision and no chipping. It produces no burrs or broken materials during long-term pelletizing. Matched with a 3KW variable frequency speed regulation motor, it can freely adjust pelletizing speed according to extrusion speed, adapting to the production of particles of different specifications with accurate speed regulation and stable operation, delivering uniform and regular finished particles.

Stainless Steel Storage Bin: Made of 201 stainless steel with rust-proof, dust-proof and easy-to-clean features. Equipped with a 2.2KW fan motor, it realizes automatic air supply, dust removal and air-drying storage, which can effectively remove floating dust and trace moisture on the particle surface, ensuring dry and clean finished particles and improving particle storage quality.

National Standard Distribution Box (Including Inverter): Adopts full set of national standard electrical components and special inverter, featuring smooth speed regulation, stable start-stop and perfect overload protection. It can effectively protect motors and transmission parts, reduce equipment failure rate, ensure safe and compliant power consumption, and bring safe and worry-free operation for new users.

2. Core Product Features
3. Reinforced core components via nitriding: The overall nitrided screw and barrel are wear-resistant and high-temperature resistant, hardly worn or carbonized during long-term processing of mixed materials and recycled materials, with extremely low operation and maintenance costs.

7. Full-automatic continuous production: Automatic screen changing, cooling, pelletizing and dust removal & storage form connected processes, enabling full-line operation by a single worker.
8. Equipment Working Process

Pre-treated materials are fed into the 125 type granulator feed port → materials are melted and plasticized by constant temperature heating of screw and barrel → high-pressure filtration and impurity removal via head screen changer → plastic strips are extruded at a constant speed → water cooling and shaping in stainless steel water tank → precise pelletizing and forming by variable frequency pelletizer → dust removal and air drying by fan → material storage and discharging in stainless steel bin. The whole process is closed-loop automatic without manual intervention, with stable and coherent production rhythm.

4. Application Fields

Widely applicable to small and medium-sized plastic recycling processing plants, new material R&D laboratories, plastic product enterprises and edge scrap recycling enterprises. It can perform recycling granulation and sample production for PP/PE waste films, crushed flake materials, plastic scraps and modified mixed plastics.
