The core function of mini plastic granulator machine
Mini plastic granulator machine is a kind of mechanical equipment that converts waste plastics (such as films, bottle chips, edges and corners) into homogeneous plastic granules through heating, extruding, cutting and other processes. These pellets can be reused in production processes such as injection moulding and blow moulding, significantly reducing raw material waste. According to statistics, more than 60% of the recycled pellets in the global plastics recycling market are produced by small-scale equipment, especially in Asia and Africa, where this type of equipment is popular because of its low cost and ease of operation.This type of equipment is popular because of its low cost and ease of operation.
Comprehensive analysis of the application and purchase of small plastic granulators
1. Working principle and technical advantages
Mini plastic granulator machine usually consists of three parts: feeding system, heating extruder and die cutting device. Its core process includes:
Crushing pre-processing: break down the large pieces of plastic into fragments through the supporting crusher.
Melt extrusion: the screw heats the plastic fragments to a molten state and extrudes them into strips.
Water-cooled pelletising: the molten plastic strip is cooled down and then cut into uniform pellets by a rotating blade.
Technical Advantage:
Low energy consumption, suitable for small batch production (daily handling capacity 50-500kg).
Small footprint, flexible deployment in community recycling stations or small factories.
Compatible with a wide range of plastic types (e.g. PP, PE, ABS).
2. How to choose a cost-effective mini plastic granulator machine?
You need to focus on the following parameters when choosing:
Key indicators:
Motor power: 1.5-7.5kW model is suitable for startups, processing efficiency and energy consumption need to be balanced.
Screw material: nitrided steel or double alloy screw more wear-resistant, life extension of more than 30%.
Temperature control precision: within ± 2 ℃ can avoid plastic degradation, to ensure the quality of pellets.
3. Synergistic application with stretch film equipment
In the packaging industry, mini plastic granulator machine are often used to form closed-loop production chains with stretch film machines and stretch film rewinders:
Waste stretch film is regenerated into pellets by the granulator.
Pellets are reprocessed into packaging film by stretch film machines.
Stretch film rewinders slit and rewind the finished product to improve secondary utilisation.
This combination of modes can reduce the packaging enterprise 30%-50% of the raw material procurement costs, and at the same time comply with the requirements of the EU REACH and other environmental regulations.
4. Domestic and foreign technology comparison and market trends
Domestic technology highlights:
Adopting frequency conversion speed control technology, energy consumption is reduced by 15-20% (refer to the data of China Plastic Machinery Industry Association).
Modular design, easy to maintain and upgrade.
International innovation direction:
German companies introduced AI visual inspection system, real-time monitoring of particle uniformity.
Japan develops low-temperature extrusion technology to reduce the problem of plastic thermal oxidation.
Future prospect of mini plastic granulator machine
With the advancement of global circular economy policy, mini plastic granulator machine will continue to develop in the direction of intelligence and energy saving. Enterprises that combine stretch film rewinding machine and other ancillary equipment can not only improve the resource utilisation rate, but also expand the high-end application market of recycled plastics (e.g. auto parts, 3D printing consumables). Users are advised to give priority to manufacturers that have passed ISO9001 certification when purchasing, and to regularly maintain the screw and heating system to ensure the long-term stable operation of the equipment.
