With its profound industry experience and technological innovation capabilities, Kitech Machinery has successfully customized a high-performance, small-scale hard plastic recycling and washing line for a Spanish client. This solution, centered on a stable processing capacity of 500-800 kg/hour, achieves efficient conversion from waste plastic to clean plastic flakes, fully meeting the client's needs for continuous, stable, clean, and high-yield plastic recycling production.
During the trial run, the production line underwent comprehensive testing on various small industrial hard hollow bottles (such as cosmetic bottles, detergent bottles, and personal care bottles), demonstrating outstanding performance. Not only did it meet the production capacity targets, but it also showed significant advantages in cleanliness and material consistency, laying a solid foundation for the client to achieve large-scale, sustainable plastic reprocessing.
I. Complete Process Flow
Belt Conveyor → Manual Sorting Belt →Wet Crusher → Screw Conveyor →Flotation Washing Tank → Centrifugual drier→ Storage Silo
Each stage is closely connected, forming a closed-loop processing system to ensure that materials are effectively processed at every stage.
II. Belt Conveyor: Stable feeding and initial metal removing
Equipped with a rubber belt conveyor with metal detection, it can smoothly and evenly transport plastic waste to the subsequent processing stages. The metal detector removes metal foreign objects at the initial feeding stage, effectively protecting subsequent crushing and washing equipment, reducing the risk of accidental damage, and providing a guarantee for continuous production.
III. Manual Sorting Convey: Key quality control points
Despite the increasing prevalence of automation technology, manual sorting still plays an irreplaceable role in ensuring the purity of recycled plastics. Manual sorting can efficiently remove non-target plastic bottles and other mixed impurities, which helps to improve the quality stability of subsequent recycled plastic products, especially suitable for the production of recycled plastic with high purity requirements.
IV. Wet Crusher: High Efficient Crushing
The crusher is specifically designed and developed for materials such as plastic films, small hollow bottles, and PET bottles. Kitech Machinery can customize the rotor structure for clients based on the morphological characteristics of different materials to achieve the best crushing effect. This equipment is widely used in the recycling of plastic films, large plastic pallets, large pieces of plastic scrap, and waste plastic bottles. Considering the specific production needs of customers, it utilizes wet crushing, adding water during the crushing process to achieve fine crushing through the friction between the liquid and the crushed material. The online water circulation tank saves water resources while ensuring efficient and continuous production.
Main Advantages
1. Superior Environmental Performance
Wet operation, through the circulation of water surrounding the crushing process, significantly suppresses dust diffusion, preventing plastic dust from polluting the air. It eliminates the need for additional complex dust removal equipment, better meeting environmental emission requirements. Simultaneously, the water flow can absorb some harmful gases, improving working conditions for operators.
2. Lower Equipment Wear and Tear
During crushing, the water flow acts as a lubricant and coolant, reducing the friction coefficient between the blades and the material, minimizing blade wear and heat generation, and extending the service life of wear parts. Compared to dry crushers, which experience frequent blade changes and equipment overheating shutdowns due to high temperatures and dry friction, wet equipment has lower maintenance costs and greater operational stability.
V. Floating Washing Tank:Efficient cleaning and sorting
The crushed plastic flakes are evenly fed into the washing tank via a screw conveyor. The tank body features a unique design with a sediment cleaning screw at the bottom and a floating material cleaning propulsion roller at the top, enabling effective separation and cleaning of light and heavy impurities. Through the combined action of water flow agitation and mechanical friction, stains, mud, sand, and residual labels attached to the surface of the fragments are thoroughly removed. This equipment is suitable for various common plastics such as PP, PE, and PET, and can be used with a complete cleaning line or independently, offering high flexibility.
VI. Centrifugual Drying and Silo Storage: Ensuring Material Dryness
The cleaned plastic fragments enter a high-efficiency centrifugual drying machine, where a large amount of surface moisture is removed through centrifugal force. The material is then transported to a dedicated storage silo.
The silo features a ventilated and moisture-proof design, maintaining a dry environment for the plastic fragments, preventing mold growth or affecting subsequent processing quality due to residual moisture. This truly enables "ready-to-use" material, providing high-quality intermediate products for granulation, blow molding, injection molding, or direct sale.
This customized plastic washing line from Kitech Machinery not only focuses on processing efficiency and output, but also embodies the concepts of clean production, resource recycling, and stable operation in every detail. It provides our Spanish customer, and indeed the global plastics recycling industry, with a reliable, advanced, and highly cost-effective recycling solution. We are committed to empowering the circular economy through technology, helping our customers achieve both environmental protection and economic benefits.
